One boy will stop at nothing to be the world's strongest... not even challenging the transcendent arts. After settling things with the human-demon hybrid, Matthias begins to piece together a theory about what occurred during the long years before his reincarnation in the current era. The severe regression of magic civilization and appearance of devastars seem to hint at the possibility of space monster involvement. If Matty's theory is correct, he'll need to craft a transcendent weapon to deal with the very monsters he felt underpowered to fight as Gaius!
