This wasnt suggested but I know you all wanted it ;)
Toko wont go anywhere unless komaru is there with her.
Komaru usually has to talk to someone else for toko cuz she doesnt like to talk to people
Toko is VERY clingy (though she denies it)
Komaru will literally pick up toko randomly for no reason but fukawa doesnt atop her she usually let's her get her way
Genocide jack gives komaru pet names or other nicknames you call your significant other (sexy, baby, cutie pie, etc.)
Gj (genocide jack but shorter since I'm lazy) becomes more dominant
Komaru is sorta scared of Gj even though she knows she wont harm her
