How about the Sakamaki and Mukami brothers’ s/o letting them hang upside down from her finger while they are in their bat forms?

Admin Mawile: (*´・ｖ・)

Shuu: He’s extremely likely to fall asleep there, and you might want to keep one hand ready to catch him when that happens. 

Reiji: It’s rather undignified to cling to you like he’s some kind of pet, and you’ll probably be sternly punished later to prove he’s still in charge. 

Ayato: He can’t stay in one place for long, and quickly migrates from your finger, to your shoulder, and eventually to your chest. 

Kanato: He’s a very prickly little bat, and intentionally pokes you with his claws just to see you squirm. Your pained faces are just too cute. 

Laito: Once he’s back in human form, he’ll have all kinds of nasty jokes to make about the incident, but he’s surprisingly quiet and still as a bat. 

Subaru: He’s very flustered by the whole thing, and tries not to look at you for too long, hiding behind his wings just to avoid it. 

Ruki: He doesn’t like feeling so small next to you, and will only perch for a moment. You can’t start thinking he’s anything less than your owner. 

Kou: He’s not fond of being in his bat form, and even less fond of you being so large and strong compared to him. He does not hang there for long. 

Yuuma: He’s big for a vampire bat, and you may not be able to hold him up for long. He doesn’t perching, though, and will stay as long as you can take it. 

Azusa: He’s happy to do anything that puts him close to you, and is very willing to snuggle up in your hand instead of hanging from it.
