BlazBlue: Phase Shift 1

BlazBlue: Phase Shift 1 (ブレイブルーフェーズシフト1) is a light novel written by Mako Komao, published by Fujimi Shobo and illustrated by Katō Yūki. It was released in April 2011.

Description
The story revolves around Kazuma, a young student of the Magic Association that looks like Hazama. Celica apparently dislikes him and feels uncomfortable being around him. It seems that he is actually not human, and was created by Relius Clover to act as a new body for Yūki Terumi (who it seems loses his previous body whenever the Black Beast appears and vanishes). Terumi does not take over the body, rather he needs to form a mutual pact with Kazuma to fuse with him.

To try and stop that, Mitsuyoshi's younger brother, Tomonori, goes after Kazuma to kill him. He arrives too late and Terumi has already obtained the body. Terumi uses Ouroboros to kill Tomonori, but then gets defeated by Mitsuyoshi and Valkenhayn, and is sealed away by Clavis Alucard until the Great Dark War, when Konoe disregards the potential danger and unseals him. She uses a restricting compulsion spell on him called "Mind Eater'" that basically makes him a puppet that has to follow her orders and help them defeat the Black Beast.

Synopsis
AD 2106. The world is in chaos from the threatening Black Beast. At the Magic Association-governed island Magic City Ishana, a student Kazuma lives a normal life. But when he meets Yuuki Terumi by chance, history receives a new Phase Shift.

"If you can get the Blue, you can take back whatever you want. Things you lost, things you forgot, whatever."

Is that the prelude of destruction? Or a gospel of salvation…?

Within the light and darkness of the Boundary, hope and despair blend together. The curtain for a new episode of BlazBlue's official story has been raised!
