Jin Kisaragi/Biography

Heart to Heart, Remix Heart
At the Academy, Jin met Taro Sasaga'e and Akane Teruhiko, becoming close to both as all three of them were roommates, and all had joined the student council. In his second year, Jin won the Torifune Festival's martial art tournament, becoming its 'Izanagi' for the year. He largely neglected his duties, however.

After having saved the girls from pit they fell into, Jin was seen again in the Torifune Festival of that year. He won the tournament again, this time it being 'rock-paper-scissors'. Jin also introduced Tsubaki to Taro and Akane, having frequently mentioned her in the past. Jin also met Kajun Faycott and Mai Natsume, with the former working alongside him as the 'Izanami' of the year. Jin also helped judge during the sports festival and was confused when Team Remix Heart managed to bring back the Conversion Grimoire - he talked to Estella McKenzie about the incident.

The weather system that manages Torifune eventually broke down, returning the city to its natural state of perpetual cold. Taro accidentally shoved Jin into Team Remix Heart, causing them to slide across the icy pavements until they hit Akane's igloo and were sent careering into the distance, landing at a beach. Jin refused to use the Golden Angel that Kajun had provided, and they waited until they were picked up by Torifune officials. In the meantime, they had fixed the Regulation Grimoire, and brought the weather system online. Days later, Jin felt Ragna's presence in Torifune.

Because Taro had kissed Mai, he took on Noel's "death dinner" cooking, sending him, Jin, and Akane into a bedridden state. Remix Heart, bar Noel, looked after the boys, and Jin joked that Mai couldn't possibly be in love with an "idiot" like Taro. He was introduced to Shiori Kirihito, although he was never made aware that she was an assassin hired by Kisaragi members to kill him. He was gifted some porridge by the girls, but Taro quickly ate some of it before Jin could even taste it. However, Jin felt Ragna's presence on Mai, and Yukianesa's influence began to take hold. Hypnotised by the Nox, Jin wildly attacked Mai while Taro attempted to stop his movements. Noel soon arrived, using the Arcus Diabolus: Bolverk to temporarily distract Jin, allowing for Cypher Albar to intervene and knock him unconscious - Jin was carried back to a different dorm, as he had destroyed the one he had been staying in.

Thanks to the Yukianesa incident, massive icebergs had been created around Torifune, and Jin was ordered to help manage them with everyone else who was involved. He watched Taro battle Shiori in eating shaved ice and was not pleased when a Torifune panda attacked Tsubaki. While bathing with Taro and Akane, Jin watched as the former was gifted an Ars Magus sealed letter and could not open it. Taro begged for Jin's help, but he refused.

Jin was soon gathered to help break Mai out of an alchemy induced coma, but he and the other students present were ensnared in the trap laid by Cypher. Taro saved Jin and Akane from the alchemy barrier created, and watched as Mai not only awoke from her coma, but also battled Cypher one-on-one. When the professor teleported away with Shiori and Mai, Jin took control, ordering everyone present (Taro, Noel, Tsubaki, Kajun, Chachakaka, Estella, and Makoto) to gather all the strongest Ars users to create a barrier of Ars Magus that would stop Cypher's plan of creating a Burning Red Grimoire - he also ordered Akane to evacuate the student body. They succeeded. Jin was told that Cypher was nowhere to be found after both Mai and Shiori were rescued from the lower levels of Torifune, and he wished to speak with Chachakaka, but she relented. Jin, with the rest of the student council, was then swamped in paperwork surrounding the event.

Later that year, Jin graduated.

Spiral Shift, Variable Heart, Determination
In the aftermath of the war, Jin was promoted two ranks, becoming the youngest Major in the NOL's history, and Jin went to his medal ceremony in the 2nd Hierarchical City of Iwatsuchi with Taro.

Variable Heart
Kagura told Jin about the whereabouts of Meifang within the 11th Hierarchical City of Shinatsu, ordering the Kisaragi heir to arrest her on grounds of treason. He willingly went, travelling to its cauldron and reunited with Mai, also meeting Bell. Upon entering, he froze solid one of the many Fuzzy as snow began to fall in the enclosed space. He talked to the Colonel, letting her know that he was going to cut her down, remembering the deaths of the Ninth Squadron, Grimwood's execution, and Karenjina's torture. The two began fighting while Mai battled the numerous Fuzzy. Eventually, Mai launched her Legacy Weapon, the Gallia Sphyras: Outseal towards Meifang, puncturing a large hole in her shoulder - Jin followed up by freezing parts of her, yet it was not enough to take the Colonel down.

Jin lost sight of both Mai and Meifang as the former created a Phantom Field. The Colonel was defeated and Jin left with Taro pursuing him. He was reunited with Akane and Taro for a brief moment aboard an Ars Magus vessel.

purgatory hell
Not long after his promotion, Jin was given a book called the "Biographies of Heroes". He looked at the book, and felt disdain towards it, mentally remarking that most of his biography had been vastly dramatized; regardless, he signed off a check-sheet to say that the book was acceptable for publishing. Jin was interrupted by Noel, who handed him a letter telling him that she had been placed under his command as his secretary. This greatly annoyed him, and he dismissed her before losing his temper at Yukianesa.

The following day, Noel handed him a letter from NOL headquarters. The letter detailed that Noel was to be deployed to the 13th Hierarchical City of Kagutsuchi and to watch the Grim Reaper - Jin learned here that the Grim Reaper is in fact Ragna the Bloodedge, his long-lost brother. The Major began to maniacally laugh to himself before leaving his office, making his way to Kagutsuchi and abandoning his post.

"A major of the NOL hailing from the Kisaragi family, who earned the title "Hero of Ikaruga" by ending the Ikaruga Civil War. Although he is supposed to be faithful to the NOL, one day he suddenly ignores his orders and heads to the 13th Hierarchical City of Kagutsuchi."

BlazBlue: Calamity Trigger - Part 2
On the 30th of December, Jin found himself within the district known as Roningai. Here, he was found by Bang, but the major failed to recognize the ninja. Bang attacked in vengeance for Tenjo but Jin defeated him, having used Yukianesa to freeze parts of the district. He refused to kill the ninja, remarking that he was not worth the effort of killing. As he left, Jin began to mutter; each breath dripping with lust for Ragna's death. The following day after having crossed over most of Kagutsuchi, he came across Noel who had been ordered to apprehend him and bring him back to headquarters. He ran towards her with Yukianesa drawn, swinging at her but barely missing. The two fought, but Noel was saved as Hazama created a smokescreen for her to escape.

Jin finally made his way inside the Kagutsuchi NOL branch, finding it was empty. He expressed a brief joy for it being so; it would mean no one would interfere with him battling Ragna. Soon enough, his brother arrived, and Jin drew Yukianesa, rushed towards Ragna and clashed against Aramasa. Throughout the fight, Jin's unbridled laughter illuminated the Cathedral, yet he was not strong enough to defeat Ragna. Eventually, Jin was beaten and sent unconscious, his last thoughts being on how cold his hands were. He was found by Noel and Hazama - the latter had him detained on an Ars Magus vessel hovering around Kagutsuchi's airspace.

Continuum Shift
"An Ars Magus of the 4th Thaumaturgist Squadron with the position of major, known as the "Hero of Ikaruga" due to his victories during the Second War of Ars Magus. Despite being treated for injuries from the previous incident, as if being led towards something, he heads for the Kagutsuchi branch of the NOL."

Chrono Phantasma
"Although praised as the Hero of Ikaruga, Jin Kisaragi has split from the NOL due to certain events. Released from Yukianesa's curse through the Power of Order and having received Jubei's teachings, Jin heads towards Ikaruga."

Central Fiction
"A captain of the NOL, from the famous Kisaragi family. Although he was supposed to be faithful to the NOL, one day he suddenly ignored his orders and left for the 13th Hierarchical City of Kagutsuchi. Only he remembers that he once held the title of Major and was hailed as the "Hero of Ikaruga.""

The fight against Ragna had seriously injured Jin and he had no recollection of it afterword. He was unable to move, and even Celica’s healing sorcery was not enough to heal his wounds. Celica left after some time, and Tsubaki visited him. He explained his relationship with Ragna, and his earliest memories to her, including the day he cut Ragna’s arm off under Terumi’s influence. They were interrupted by Noel, whom Jin had sent for earlier, and Tsubaki left. Noel told him what happened in the fight, and he ordered her to find Ragna before Tsubaki would. Trinity Glassfille was watching, and he spoke to her after Noel had left; they formed a pact, and Trinity, using alchemy, made his body able to fight again, although at the cost of him being unable to ever fight afterwards. Jin was later absorbed into the Embryo but the Power of Order prevented his memories from being altered.

Part of his pact with Trinity was to find Platinum the Trinity, which he attempted to do inside the Embryo. He found his way to the Monorail in Kagutsuchi. Much later on, he would find Jubei, and they discussed the latter’s distorted memories. Jin left his mentor to go and investigate the strange world they were in. He was teleported to Ikaruga by Nine, and instructed to defeat Izanami to claim a part of the Azure. Jin trusted Trinity’s instinct to go to Kokonoe to complete both their goals.

With barely any time left, Jin and Trinity found Platinum, whose existence was on the verge of disappearing. He perceived both Luna and Sena, recognizing them with the Power of Order. The measure was only temporary, so Jin resolved to help Trinity make it permanent. The three of them broke into a Sector Seven facility and escaped with information pertaining to Platinum’s body. He allowed Carl to help Trinity with modifying Platinum’s body so they could exist within the Embryo.

After finishing the maintenance and saving Platinum, the trio left Carl and were found by Jubei, who warned them of the eleventh Nox Nyctores. They travelled to the Kaka Village first to drop off Platinum so she could materialise the Hihiirokane, which Jin concluded could outright kill Terumi. Later, Jin travelled with him to Yabiko where they found Celica, Noel, Ragna, Kokonoe, Kagura, and Rachel discussing how to break into Nine’s workshop. He told Kokonoe it was impossible to naturally enter the workshop. The following morning, Jin was part of the strike squadron sent to Nine’s workshop. There, he listened to Nine’s explanation of the world, the Prime Field War, her desire, and why she created the Corpus Sepulcro: Requiem. Although he believed her a threat to Order, he could not attack her because it would drain his body far too much. He watched Ragna defeat the sage, and attempted to fight off both Izanami and Nu, who had come to kill them all. He could not fully fight, however, and was teleported away after watching Nine die to delay Doomsday and stop Izanami from moving for a week – he was also forced to leave Jubei behind.

Jin and the others were teleported to the church that he grew up in, leaving him shocked as to how it could exist, even within the Embryo. While the others went inside, Jin and Ragna talked about how it could possibly exist before deciding to go to the nearby river – both completely calm and not at one another’s throats. They returned to the church to sleep, and had breakfast together with Celica and Noel. He left the building and talked with Rachel, Trinity, and Ragna about the situation at hand and agreed to “play house” for the time being. Jin also listened to Noel perfectly describe his childhood through Saya’s eyes, calling it “impossible”. The hero later listened to Trinity’s request to stay inside Yukianesa so she could help him to defeat Izanami and Terumi, and he complied. The following morning, he watched Celica finally die, and the group teleported back to Yabiko – it’s unknown how her death affected Jin.

Jin would be reunited with Tsubaki, Kagura, and Kokonoe back at the Yabiko branch, and also met Hakumen. He listened to Noel, learning that she holds one half of Saya’s soul, and agreed to be sent within the Embryo’s frozen space-time to deal with Requiem and Izanami, being taken there by Lambda-11. Inside, he was separated from the others, being stranded with Kagura. They were found by Azrael, who shifted space-time to fight them in the Colosseum. After watching Kagura fight the Mad Dog to a near stalemate, Jin intervened, using "Artic Dungeon" to freeze him, and the two became the first pair to ever defeat Azrael. Jin left Kagura behind to rest and travelled onwards to find Requiem.

The final part of Doomsday began to occur, leaving Jin and Trinity stranded in the White of Nothingness. They soon ventured to find the others and Amaterasu. He eventually did, finding Tsubaki, in her Izayoi form, alongside Hakumen battling Nu. He watched Ragna defeat both Nu and Hakumen, and then Terumi breaking Hakumen’s soul and taking the Susano’o Unit for himself, becoming Susano'o once more. Jin watched him snatch Noel and transport both himself and the Amaterasu Unit outside of the Embryo. He learnt from Trinity how to escape the Embryo to follow them and journeyed with Ragna to the Kagutsuchi cauldron to do so. There, he saw Hazama jump into the Boundary and found Rachel. With Ragna, Trinity, and Rachel, Jin jumped into the cauldron, ending up on the exterior of the Embryo.

Outside the Embryo, Jin and Ragna fought against Susano’o, although the hero had reached the limits of his body after perceiving the God using Order. Ragna dragged Terumi out of the Unit, and Trinity transferred him into the Susano’o Unit with Hihiirokane, and he slashed down both his brother and the God, although both were dragged into the Gate. Terumi was killed by the Grim Reaper, and when Ragna exited the Gate, he fought against both Jin and Noel, taking their dreams. Trinity took Jin out of the Susano’o Unit. Jin began crying into his brother’s arms, knowing this would be the last time he would ever see him. Together with Noel, who had now reclaimed all of Saya’s memories, they returned to seithr.

In the new world created by Ragna, Jin forgot about his brother, and was last seen at an NOL ceremony where Homura presided – both Kagura and Hibiki were also present. True to Trinity’s deal, Jin is now incapable of ever fighting again in his life.
