Celica A. Mercury

Celica Ayatsuki Mercury, sometimes known as the Sister, was the younger sister of Nine the Phantom. She was an excellent user of sorcery and magic, being one of the few people in existence capable of exceptional healing sorcery. After surviving through the Dark War, Celica became a nun, looking after Ragna the Bloodedge, Noel Vermillion, and Saya before being brutally murdered by Yuuki Terumi. A copy of her soul when she was a young woman was made material by Kokonoe and she died shortly after watching Nine sacrifice herself.

Celica has been the wielder of both the Nox Nyctores - Deus Machina: Nirvana and the Ex Machina: Minerva. She made her debut in BlazBlue: Phase 0 before appearing in BlazBlue: Chrono Phantasma. Celica was made playable in BlazBlue: Chrono Phantasma Extend and is one of the main protagonists of XBlaze Lost: Memories.

Central Fiction
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 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.

In Kazamotsu, Celica found Ragna. Reunited, they travelled together to Yabiko to find Kagura, Noel, and Kokonoe. The young mage told him of her dream for everyone to be happy and they eventually found Yabiko together. 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.

They arrived at the 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.
