Kaneki
– his s/o would probably need to reassure him that they’re okay doing things on their own.
– His s/o likes teasing him that they see him better than most. Because they understand his personality so well.
– Kaneki may have once tried to break up with them during his Shironeki! phase, for their safety. “Breaking up with a blind person is just cruel,” they wheedled, and he laughed as he realized how much he’d miss them.
– Even if it’s selfish, he’s gonna stick with his s/o forever.
Eto
– She can’t resist teasing them on occasion by moving furniture.
– Her s/o occasionally taps her with her walking stick in retaliation. It’s all in good fun.
– despite her nonchalant act, Eto cares a lot. She once tried to use her kagune to heal their sight. She was devastated when it didn’t work – and by that, I mean she went unusually silent for an hour.
Tsukiyama
– He immediately buys them the largest, floofiest service dog imaginable.
– He then convinces Mirumo and the Tsukiyama household to start training service dogs.
– He really loves giving his s/o the widest breadth of sensory experiences to make up for their lack of sight. Especially gustatory. 😛
Ayato
– he was originally afraid to bring it up lest he come across as tactless.
– to which his s/o replies that his tactless nature is part of his charm.
– He’s confident in their abilities to take care of themselves, but he also can’t bear to think of CCG ever coming near them.
Amon
– He’s mildly overprotective, and this is a sort of conflict at the start of their relationship.
– Eventually, he checks himself when he realizes his s/o is actually hurt.
– They love hearing his tales of heroism and activities. Once he becomes a kakuja, they hunt him down themselves after never believing he died at Anteiku.
– They become a Team to be Reckoned with as they spy on Aogiri and CCG alike.
