I know that it might be just a little thing to throw us off but I refuse to belief akechi is dead especially after the post credit scene. Tbh I never believed he was dead from the start because they never explicitly said it. They closest they got to saying he died was when ryuji mentions how he thought hard even though he knew he was gonna disappear. Now I know nothing about P5 Strikers, I don't know a single thing except the it's Canon (I think it is at least) but I really hope that when I am able to play that he's in it because to be honest I really liked akechi. Not from the beginning but his character ark was amazing when it got to shidos Palace onwards. I just really hope they bring him back whether it be in P5 Strikers or and different P5 game. Maybe even P6 (whenever that happens).
