Were you looking for Seraphic Radiance, the boss character?
Seraphic Radiance is the most powerful fusion in the game.
It is an entirely optional and potentially missable fusion, that requires certain conditions to be met before it be acquired;
- Yuri must have every fusion monster (including Amon)
- Must have collected the Rebirth Stone found in the Ancient Ruins.
Defeating them will allow its use as a fusion.
It requires 64 Sanity Points to fuse with.
Fortunately no Harmonixer has yet to fuse his soul to create this being, for its very appearance signals the apocalypse.
In the year 1913, Earth Sage Dehuai used the Reverse Demon's Gate Invocation to summon the Seraphic Radiance into his world. Yuri Hyuga attempted to fuse with the creature at that time. Unfortunately, he failed, and the Seraphic Radiance ravaged Shanghai.
Later, when Yuri is returned from the darkness, he finds the Seraphic Radiance still within him, sealed away out of fear of its power. After battling with the creature as well as himself, he is finally able to control it.
