Opera-san from m!ik/wtdsik and illumi from hxh are really similar.
I feel like Illumi has traits that aren’t spoken about as much in the HXH fandom. like i feel if you two were married, he would come up to you and be like “you know (child’s name or killua) said that if you don’t kiss me that they’d hate you.” And you can just tell he wants some kisses but is too embarrassed or ask. I feel like he’d joke but you can’t tell if he’s serious or not with the stonic face.
With this, i feel Opera-San from m!ik/wtdsik is similar to Illumi in a way. Extremely powerful, stonicnface, joking with that same stonic face. Like they’d be similar to Illumi by saying “Iruma kun said if you don’t kiss me, he’ll hate you.” Leaking a sort of aura similar to bloodlust but harmless, and then if you say something like “no he wouldn’t” to either of them, they would just be like “hes my (brother/child) how would i not know?” Or opera-san would be like “wow so are you saying i’m lying, i live with iruma-kun 24/7 how would i not know.”
I also feel like those two would often ask for affection in discreet ways, you’re laying in bed next to them and they suddenly rub up closer to you, trying to hint at it. Or after a long day of work, you may just be sitting in the edge of your bed and they come and just lay their head on your lap. Opera-san definitely purrs, no doubt.
