Celica A. Mercury/Biography
Celica grew up and enrolled into the Mage's Guild on Ishana, becoming a student with average grades. In 2100, the Black Beast arose from Japan and the Dark War begun. Shuichiro was blamed for its appearance and he disappeared, presumed dead. Celica and Konoe grew much closer, but her sister's relationship with their father did not mend, leading to the sister bickering over the subject countless times. She became good friends with Trinity Glassfille, Konoe's best friend.
Konoe was chosen to become one of the Ten Sages - Nine. After the Canonization Ceremony, Celica and Trinity found the newly appointed Nine exiting the Ishanan Cathedral. Although Celica was disheartened that her sister had now changed her name, she was pulled into a giant embrace by Nine and told that no matter what, they would always be sisters, and that they would always love each other. Celica decided that they could celebrate by getting lunch together at the cafeteria.
At the cafe, the girls met Kazuma Kval, and Celica took an immediate shining to him, begging him to allow the group to sit with him. He allowed it, and Celica's happiness shone through the cold remarks that Nine was constantly dropping to the boy. As she ate spaghetti bolognese, Celica listened to Kazuma talk about classes. Before she could finish her food, Nine dragged her away and told her to stay away from him; Celica retorted and they bickered until a nearby television burst to life and ran the news that a Japanese survivor has been found. The sister's stopped in their tracks, but Kazuma fell ill - Celica attempted to help him, but her hand was smacked away and the boy ran to the infirmary.
Nine soon felt an unusual presence in downtown Ishana, so the trio of girls went to investigate. They found Kazuma in an alleyway next to a destroyed cobble road. She saw the boy was injured and offered to use her healing sorcery to recover his wounds but was rejected. Instead, the girls walked him back to his dormitory.
Together with Trinity, Kazuma, and Nine, Celica enjoyed a caramel cake and lemon tea in a cafe. She told the boy about her sister's incredible sweet tooth, telling him that her sickly sweet coffee is something she needs to relax her mind. She was then interrogated by her sister over her failing grades in lightning sorcery, but boasted of her ability to levitate for long distances. When Kazuma brought up Shuichiro, Celica and Nine began to have another one of their fights over the man, and both knocked tea over Trinity, causing her to greatly scold the two of them for their behaviour. Kazuma then ran away.
Celica was called out by Kazuma to the edge of Ishana. He dripped poison into her ear about Shuichiro possibly surviving in Japan, using the other survivor had been found recently as part of the persuasion. She learned that the survivor did not think he had been stuck within Japan for six years, but rather two because of a time distortion near a cauldron. Although hesitant, Celica learned that civilians could visit Japan, and it was not just a militarized zone. Excited, Celica also learned that there was a small hole in Ishana's barrier that she could escape through.
The young mage ran home and quickly wrote a letter addressed to Nine, Trinity, and Kazuma that told them that she would be going to find Shuichiro, but would return. She then excited through the barrier and used levitation sorcery to take her to a port that could ship to Japan. When she arrived, she stayed at a local hotel before making her way to the harbor. As she climbed a mountain to get to the port, Celica got lost, but she found a young man with a bright red jacket slumped against a tree. She immediately began to tend to him.
Celica took the man into a nearby shack and tended further to him. When the man finally awoke, he introduced himself as Ragna the Bloodedge, and Celica explained about her sorcery. She learned that he was suffering from amnesia and could not open his right eye. Together, they set off towards the nearby port town, with Ragna accompanying on the chance that clues towards his memories might be there. En route, they were ambushed by seithr-mutated dogs after Celica had left them lost with her terrible directions. Ragna defeated them, but Celica healed the dogs back to health, having felt sorry for them.beastkin. The creature, who introduced himself as Mitsuyoshi, fought against Ragna, and the two battled until Celica stood between them, demanding them to stop. Mitsuyoshi told them of his objective - to head to Japan and capture Shuichiro. Shocked, Celica told him that Shuichiro is her father, and begged to know why her father was being hunted. She learned that he was likely responsible for the appearance of the Black Beast, and convinced Mitsuyoshi and Ragna to accompany her to Japan so she could find Shuichiro. Together, they made their way to the port town.
After securing an inn with Ragna and Mitsuyoshi, the three of them had dinner together. The beastkin soon left to gather intelligence, and the young mage went out to the harbor to gaze at the sea and stars. Ragna soon joined her, and Celica explained her family to him, talking about Nine's status as one of the Ten Sages and Shuichiro's numerous scientific awards. Lamenting on how she left Nine back on Ishana, Celica straightened her back and the two of them began walking back to the inn. She briefly lost track of Ragna, but still managed to find her way back.
The following morning, the trio travelled to Japan, catching a boat from the harbor to the country. Mitsuyoshi acquired transport from the United Nations, leaving Celica stunned and in awe of his position in the world. Ragna, Celica, and Mitsuyoshi sat in the back of a pickup truck as they were ferried around the barren wastelands that had once been Japan. Celica in particular was hopeful that in close to 100 years that the land might be fertile again, earning a chuckle from Mitsuyoshi as he lamented over the state of his country. Eventually, they found the Seioudai Sampling Laboratory where Shuichiro once worked and that Celica recognized from a visit in her childhood. Together, the trio entered the building, searching for the man but finding nothing. Once in the courtyard, they were attacked by a Remnant of the Black Beast, and Celica was helpless as she watched both Ragna and Mitsuyoshi give all their might to combat against it - they lost. The Remnant faded away, although Mitsuyoshi lost his eye from the encounter; Celic desperately tried to heal him, but the wounds could not be healed with her sorcery. They were met by a young vampire, Rachel Alucard, who offered them the chance to save him. Celica and Ragna took up the offer, and the former was shocked as the runes of teleportation sorcery flashed underneath them.
Inside the Alucard Castle, Celica and Ragna were ordered to stay in the parlor by Rachel as a butler carried the bloodied Mitsuyoshi into the inner sanctum of the Castle. Soon enough, both of them were introduced to the master of the Castle - Clavis Alucard, and his butler, Valkenhayn R. Hellsing. Clavis told Celica that he was the one who ordered the capture of Shuichiro, and she listened to his explanation on the discovery of the Susano'o Unit, the cauldrons, and Shuichiro's pursuit of the creation of a Kusanagi. Left to process the revelations set before her, Celica and Ragna were guided to the second floor by Valkenhayn as they were offered a place to stay for the night.
Later that evening, Celica found Ragna in the Castle's hallways. He expressed his worry about her after hearing about what Shuichiro had done; regardless, Celica told him of her resolve to still find her father, and the two agreed to continue on their search for the scientist. Clavis gave them a map for the First District and they ventured out to Japan one more. Now in the Kantō region, Ragna and Celica ended lost on a ragged trail thanks to Celica's direction. Ragna attempted to snatch the map away from her, but was interrupted by powerful sorcery attacking him. Turning to see the person who shot the sorcery, Celica turned pale as she saw it was Nine, with Trinity close behind.
Celica quickly jumped in front of Ragna to prevent Nine from hurting him. Both Nine and Celica entered into an argument about the man, with her older sister jumping on the offensive and immediately kicking Ragna when he interrupted their conflict. Celica began crying, and the situation was only diffused when Trinity offered them all tea. Nine and Celica, however, continued to argue, although this time it was about Shuichiro and the latter's search for him. The argument ended as Celica's resolve to search for her father swayed both Nine and Trinity into joining the search, and the new group travelled towards the First District.
Upon making it to the District, Celica was amazed by the technology used there. They soon discovered an elevator, and Trinity noted how the area was protected by alchemy. As they descended down into the depths of the area, the elevator suddenly began to rumble and violently stopped. Ragna created an exit, and quickly pulled Celica up to a safe footing alongside Trinity and Nine. He was unable to gain any good footing, and fell as Celica screamed out his name and helplessly stretched out her arm. The three girls made their way to where Ragna fell, and saw Hakumen. He barely spoke to the women before leaving. Celica quickly ran to Ragna's side, healing him of his injuries; reunited, the group continued to search in the facility before coming across a cauldron and an entrance to an unexplored room.
Gaining access through Ragna's brute strength and Nine's electricity, the group entered the laboratory. Hung high above them was the Kushinada's Lynchpin. Nine quickly read through the nearby research notes, becoming noticeably agitated as she did so, telling Celica it was all in Shuichiro's handwriting. Nine threw the papers onto the ground and began stomping on them, and Celica tried her best to save the documents from her sister's wrath. Upon inquiring on her sister's outrage, Celica was told that the device could defeat the Black Beast.
Moments later, Shuichiro himself appeared, gaunt from his captivity in the First District. Celica ran towards him, tears in her eyes, but their reunion was cut short as Nine commanded her to get away from him. She revealed that all of his research papers were not just on the Lynchpin but on how to merge Celica with it, and that her soul was ultimately the catalyst required for its activation. Nine pushed her father against the wall with a powerful shockwave, and Celica rushed to his side, seeing sanity slip from her father's mind as began to die, all while crazily exclaiming his achievement of having surpassed Relius Clover. When he finally died, Ragna held Celica as she uncontrollably sobbed into his jacket.
Mitsuyoshi appeared from the shadows, having listened to the conversation that transpired. He began to argue with Nine over what to do, being in favour of Celica sacrificing herself if it meant saving the world. Celica helplessly watched as the two battled over her fate, but had enough and ran between their battle. Both Ragna and Trinity helped to end the conflict diffuse, and the group attempted to reconcile and talk rationally through the situation.
Trinity prepared tea for the group, and Celica sullenly drank it, still reeling from the death of her father and the revelation that she could end the war. She told the group that she was willing to die if it meant saving the world, and expressed her heartfelt love for everyone she had met. Ragna interrupted her, and told them all that there was another way - if he charged into the Black Beast. Celica, nor the others, understood what he meant, but he revealed to her that he had a younger brother and sister, and that he did not want Nine to experience losing a sibling. Ragna playfully ruffled her hair before Nine and Ragna went to talk in private.
The ground began to rumble and the Black Beast itself had appeared. Celica stayed with Nine and Trinity as her sister cast a circle to teleport them out of the area. Ragna gave her his jacket and promised to come back for her after his encounter with the Beast. Mitsuyoshi also stayed behind to help Ragna in his effort, and Celica waved at them both before being teleported away, desperately clinging to the jacket he had given her.
Now again in the Alucard Castle, Celica learned that Clavis had passed away while they were in Japan, and that Rachel had become the new head. Mitsuyoshi finally returned some time later with Ragna's sword; Celica healed him as he gave her the sword and apologised, stating that Ragna had been swalllowed whole by the Beast. She wiped his crying eyes and embraced Aramasa, the sword of the man who sacrificed himself in her stead.
As the months passed after Ragna's disappearance, Celica returned to Ishana and continued her studies. Nine had assembled a team of warriors to combat the Black Beast, including herself, Hakumen, Mitsuyoshi (who had changed his name to Jubei), Trinity, Valkenhayn, and a man called Yuuki Terumi, who bore a remarkable resemblance to Kazuma. All that Celica knew of Kazuma was that he had disappeared from Ishana, seemingly unaware that Terumi and Kazuma were two souls sharing the same body. The group of warriors that included Nine would be known to history as the Six Heroes. In her free time, Celica polished Aramasa and fixed Ragna's jacket to the point of complete restoration.
In August, 2107AD, Celica daydreamed in the courtyard of the Mage's Guild. She dreamed of being in a pure white space, in front of her a singular mirror; she shook herself awake from the vision and saw silver hair in the distance. She called out "Ragna" to the figure, but when the figure turned around, it was Hakumen atop one of Ishana's hills. The two briefly talked, and Celica remarked that Hakumen and Ragna had a similar presence. Hakumen asked her if she meant Ragna the Bloodedge, but Celica was unfamiliar with his title, only knowing Ragna's given name. Abruptly, Hakumen left to find Nine, and Celica cheerfully jogged after him, attempting to follow his large strides.
Hakumen and Celica were found by Nine and the other Heroes, who immediately embraced her younger sister. She explained that she was with Hakumen and tried to persuade Nine that it was her fault for his absence. The atmosphere was soured by Terumi's arrival and he attempted to start an argument with Hakumen - Celica broke the confrontation and attempted to grab Terumi's arm, but he did his best to avoid her, something that Celica had noticed some time ago. The group disbanded when Seven and Eight reprimanded Nine for bringing them inside the Mage's Guild. Celica was about to leave with the others, but Seven grabbed her arm and demanded that she stay. Eight began to insult Nine's companions for not being human, and Celica stood up for them, telling Eight that they were risking their lives for the world and that they should be treated with respect. Both Seven and a stunned Eight then asked Celica if she would cooperate with their research, but Nine answered before Celica could register the question - no. Nine dragged her younger sister away from the two Sages and Celica begged her sister for information on what they had been talking about; Nine dismissed this by telling Celica that they were trying to use a failed weapon.
The sisters entered their favourite cafe, seeing Jubei and Trinity waiting for them. Celica greeted them both, but her hopes of having tea with all the Heroes together was crushed. She giggled and watched as Nine flirted with Jubei, causing the beastkin to become flushed and embarrassed. This interaction made Celica happy for her sister as she noticed that this was the first time Nine had allowed herself to become close to anyone who wasn't Trinity. The atmosphere was once again soured by Terumi's arrival; once he left for the other side of the cafe, Celica attempted to lighten the mood, but accidentally pulled at Jubei's tails - he flipped the table, sending Nine's thick coffee all over Trinity and her glasses. The sisters immediately began apologizing, knowing that they had incurred the young woman's wrath.
When the group left the cafe after Trinity's long rant, Celica and Nine bid the others goodbye. The sisters walked together back to their home, and Nine promised that she had a surprise of sorts for her younger sister, and that she would have to follow her into her workshop, a location that Celica hadn't visited since she was a child. There, Nine introduced Celica to a tall doll that would become her bodyguard while Nine was away on business concerning the Black Beast. Nine chanted a spell that bound the doll to Celica, and introduced her creation as the Deus Machina: Nirvana. Celica took Nirvana's hand and vowed that they would get along before the new formed duo went to prepare dinner. Celica was made aware by Nine that the research that Seven and Eight wanted Celica to be a part of would likely result in her death.
Celica attended her classes the following day. Nirvana was forced to stay in an office until her mistress' classes were over. As they walked back home, Celica was approached by Seven and Eight. Although she was without Nine, Celica stood up for herself, telling them both that she would not participate, a statement which was backed up by Nirvana taking a firm stance between the two parties. Both mage and doll left the Sages behind, with Celica deciding that they go to the local bakery to buy breads for dinner.
Nine insisted that Celica join a war council with the Six Heroes since she was worried about Seven and Eight's plans. Within the meeting, Celica was bored, not understanding most of what was being said and feeling as if she did not belong with such a group of amazing people. She leaned on Nirvana's arm and the doll attempted to pat its mistress on the head, reminding Celica of Ragna. The meeting was interrupted by Rachel as she teleported into the room, shocking Celica so much that she tipped out of her seat. She noticed a look in the vampire's eyes when she said that she could not intervene in the world - it reminded Celica of Rachel's father, Clavis. Rachel told the group that the Beast would appear wherever Celica was because Ragna's soul was sleeping within it. That night, Celica returned home and clung desperately to the Aramasa and Ragna's jacket. She told Nirvana that she would become bait for the Beast, and that she would attempt to convince Nine the following day. That night, Celica dreamed again of a white room with a singular mirror.
It took Celica some time to convince Nine that she should be bait for the Beast, but her older sister finally relented so long as both Nirvana and Hakumen were there to protect her. She, alongside the other Heroes and battalions of newly trained Ars Magus wielders, were deployed to a desert in Eastern Europe. Standing beside Hakumen and Nirvana, the knight asked her if she felt scared, something that she confessed while trembling. He attempted to comfort her, reminding her again of Ragna. Hakumen was curious, and asked if they shared any kind of resemblance, catching Celica off guard. She told him that they were both blunt, have a similar attitude, get into arguments with Nine, and that their history is completely unknown to her. The knight told her that she reminded him of someone he once knew; he then vowed to protect Celica at all costs. Happy, she bounded to his side, but their moment together was cut short as the Beast appeared in front of them.
Celica screamed out Ragna's name to the Beast after locking eyes with it. Hakumen jumped to protect the girl and engaged the Beast in battle. Celica was helpless and watched as the battle unfolded between the Beast and humanity; Nirvana attempted to pull her away, but she refused to leave her position. Several lights started glowing underneath Celica's feet as Seven and Eight appeared beside her. Nirvana covered Celica with her arms, but the girl's power was being drained out of her by the circle which summoned Gigant: Take-Mikazuchi. She was knocked unconscious, but the summoned weapon managed to repel the Black Beast for the first time in the entire Dark War. Nine ran to her sister and cradled her.
As the Dark War ended, Celica became a nun, with her church being built by Nine and Jubei. It was erected over the sight of the Beast's death, and Celica greeted her sister and Jubei as they visited - they were soon to be wed. Celica offered them tea given to her by Trinity, and learned that they wanted to hold their wedding at her church. Overwhelmed with happiness, the three sat down to tea together to discuss the ceremony.
A mage who lived during the Dark War, and the little sister of the Six Heroes' Great Mage "Nine." By nature, she excelled at restorative sorcery and innately had an unconscious ability to surpress seithr, so Kokonoe summoned her into the present era as a "Chrono Phantasma." Equipped with an Idea Engine created by that same Kokonoe, the automaton Minerva waits together with Celica for a reunion with Ragna, who challenges his new trial with resolve.
A mage who lived during the Dark War, and the little sister of the Six Heroes' Great Mage "Nine." By nature, she excelled at restorative sorcery and innately had an unconscious ability to surpress seithr, so Kokonoe summoned her into the present era as a "Chrono Phantasma." Awakening in the unfamiliar city of "Kagutsuchi," she wanders with Minerva at her side and searches for one important to her, Ragna.
Jin was seriously injured from his fight against Ragna, and Celica tended to his wounds, staying close to his side. She did her best, but left to report to Kokonoe afterwards, bumping into Tsubaki and suggesting that she visit Jin to cheer him up. She was soon taken inside the Embryo with Minerva. 
She found herself in Orient Town in the 13th Hierarchical City of Kagutsuchi with Minerva. She came across a wanted poster of Ragna, and chirped to Minerva that they would find him and Kokonoe in the city.  Through Celica’s direction, they ended up in Bascule where they met Naoto Kurogane, he asked them for directions and described Raquel Alucard to them, although the young mage thought he was describing Rachel. They decided to travel together throughout the city.  She, Naoto, and Minerva were teleported to Ikaruga and heard Nine’s voice telling her to kill Izanami to claim her piece of the Azure. Worried for her sister, she immediately went to try and find her. 
Finally arriving at Yabiko, Celica explained to Naoto about Nine and the Dark War. She asked more about who Naoto was looking for, and began to realise that they may not be looking for the same person, and her own careless nature made her lose him in the crowds.  It took her a while to notice she had lost him, but she was soon enough distracted by finding Carl and Nirvana, the former with distorted memories. Because of said memories, Celica accidentally offended the young boy, and he ordered Nirvana to attack, but she relented as she, like Celica, knew the truth. Although upset that she had offended Carl once he left, she went on to try and find Naoto with Minerva reassuring her that she said nothing wrong.  Celica went ahead to assess the situation of the people’s distorted memories of Ragna, only managing to get inside the branch because of Minerva’s directions.  Hibiki found her, and they went together to Kagura’s office  – Kokonoe explained to her that she unable to find Celica because of the teleporter malfunctioning due to the mismatched coordinates of the Embryo.  She was upset with her niece’s decision to send Tager to capture Ragna.  She reunited with Ragna once he was brought back to the branch, and listened to Kokonoe’s explanation of the existence of the Corpus Sepulcro: Requiem, also learning that Nine’s transformed her father’s workshop into her own. 
She was later part of the strike squadron sent to Nine’s workshop. Celica watched as her sister beat Jubei throwing him at her and the others. She listened to her explanation of the world, the Prime Field War, and why she had created Requiem. Celica held Jubei as Ragna fought Nine, and rushed to her sister’s side when she was defeated.  Izanami arrived, and began assaulting the group and Celica watched as her sister used the Radiance of Extinguishment to activate Requiem and bind Izanami – she watched as her only sister died saving her, and was teleported out of the workshop using her sorcery to force Rachel into using hers, greatly reducing the time she had left in the world. church, although Celica was unconscious. Minerva carried her inside to a bed.  She awoke the following morning and made everyone breakfast and tea despite feeling generally odd.  Celica gave her permission for Minerva to takedown Requiem even if it meant her dying.  She watched the stars with Ragna later the night, and talked about Nine and her sacrifice. The following morning, Celica began to pass on, telling Ragna, Noel, and Jin that she was proud of them all before she finally died.
