-Ishimaru is always a power bottom, although:
•Ishimaru is a sub
•Kiyondo is a sub and a dom
•MM!Ishimaru is a pure dom(MM!Ishimaru is only a dom if Mondo is also the mastermind because consent is good, even the mastermind understands that)
-In the afterlife Mondo hates Celeste and Hifumi with a passion, although Ishimaru doesn't hold any grudges towards them.
-Ishimaru and Mondo have study dates together when Mondo isn't doing well in his classes.
-Kiyondo and Genocide Jack are best friends and burned down an old orphanage together.
-If Ishimaru is scared while watching a horror movie, he'll cuddle with Mondo until he falls asleep.
-They are the most lovey-dovey motherfuckers that it makes Leon sick.
-Ishimaru helps Mondo with his grades, while Mondo helps Ishimaru get over his fears.
-Also in the afterlife, Ishimaru has met Daiya, they've become good friends!
-In the AU that Kiyondo is a separate person from Ishimaru, Mondo basically has to save Ishimaru from himself. (Sounds like I'm r/14andthisisdeep huh?)
