Okay, I’ve said this in DMs but I still believe that Chikage does eventually have to leave Mankai. And when he does have to leave, he does one last roll for Itaru (Itaru doesn’t know it of course) and it’s a fucking godly roll and Itaru’s obviously overjoyed.
Itaru then kisses or hugs or whatever Chikage and then later on when he finds out that Chikage has to leave, Chikage says “Glad one of the final moments that we had together was great” and Itaru questions what if it wasn’t great, cause he doesn’t want to think of the impeding
Event and he’s trying to stall and Chikage just shrugs. “That’s just life. One final gift from your cheat Senpai”
