Ragna The Bloodedge

Ragna and his siblings were first found by Jubei in Relius Clover's workshop, where they were experimented on. Their "mother" was the 5th Prime Field Device. Jubei decided to save the three, gaining several wounds in the process, and left the three with Celica A. Mercury. Ragna grew up in her church along with his younger brother Jin Kisaragi and his younger sister, Saya.

Ten days after arriving at Celica's church and sometime before Relius and Terumi destroyed his young life, Ragna was forced, along with Saya and Jin, to go foraging for strawberries with Celica to make jam. Unfortunately, they ended up lost thanks to Celica's navigation. Despite this, they soldiered on, with Ragna carrying Saya and Jin complaining about the distance. Ragna noticed something wrong with Saya as she detected the presence of someone, but he dismissed her worry and claimed it was likely a rabbit; eventually, the smell of strawberries lead the search to a close. Sunset loomed and Ragna stood back in the kitchen as Saya and Celica made strawberry jam. He laid the table with Jin when asked, but was offered up Saya's jam to eat. Even though the jam itself looked akin to black sludge, Ragna still consumed it once prompted. He was knocked unconscious as a result.


Jin was dependent on his older brother, and frequently demanded a high level of affection and play time from Ragna. However, Saya became very ill and Ragna decided to care for her. Jin became jealous of this and began bullying Saya, causing Ragna to spend even less time with him. Jin was driven mad by the Nox Nyctores Mucro Algesco: Yukianesa, and learned of his future. Yuuki Terumi used this to convince the boy to burn down the church, while Ragna was out gathering water. He rushed home to check on his family within the burning home, but was instead confronted by Jin, who was possessed by Terumi. The two cut off his right arm and Terumi proceeded to mock Ragna, killed Celica and then kidnapped Saya to use as a vessel. He soon blacked out from the pain and shock of losing his arm. Ragna woke up as the rain put out the fire and heard Saya's music box in the wreckage. He cried out until he fell unconscious again.

Ragna tried to crawl out from the wreckage and find help some time after, but couldn't manage to prop himself up to stand. Rachel Alucard appeared before him, looked into his eyes and saw that he wanted to live. She offered Ragna the Azure Grimoire which, once he touched, saved him. The new Grimoire took the shape of a human arm and replaced the arm that had been severed. Rachel then took Ragna to Jubei, who agreed to care for him. Jubei became both his caretaker and his trainer, teaching him proper sword fighting and how to control and use the Azure Grimoire. Out of respect for him, he started calling Jubei "Master." At some point with Jubei, Ragna was introduced to both Taokaka and Torakaka.
