Nah.. for this particular one, I don't believe Akutagawa is dead. I wonder if Fukuzawa dies/absorbed by ame no gozen, the restriction on Atsushi ability will be lift up, right? Maybe he'll lose control and cause a small damage onto Fyodor or ame no gozen? Then Akutagawa using his ability restrain him and that's how their 'gatai' version is born?
