So Carl is basically "using" Relius? That makes so much more sense, even if its completely false.
So lemme break down the events so I can understand: Main events that happen.
Hakumen kills Terumi, and he takes Trinity with her.
Most of the cast join in Kagura's coup and force out Tsubaki and Jin does his thing.
Kagura was a disciple of Bang's master and wants to put his son, Homura, on the throne
Saya is possessed by Izanami, the god of death.
Take-Mikazuchi is unleashed and Nu fuses with it.
Ragna, Jin, and Noel beat the shit out of it, and they rescue Nu.
Bang, Makoto, and Tsubaki fight off Relius, and Bang activates Retenjou and eliminates seither.
Izanami makes Ragna's grimoire go out of control and mutates him into a beast and then disappears.
Is this accurate?
