Shinso had gotten a lot of new friends since he met Midoriya. The fairy was kind of a social butterfly as they would say. So; much like a magnet to iron, one by one they would drop by his cabin (or Heaven forbid phase through it) like it was a bed and breakfast place instead of private property.
They came in all shapes and sizes. Creatures of all kinds. Of all walks of life. Literally.
You had those with needle like teeth, some with four wings, others with eyes much too many. They hiss, they babble, they speak, and they chirp. It was erratic, what they could be. When snow falls some leave footprints in the wintertime, some don't. Other crunch the snow when they walk, hobble,and limp around. And some? Just don't. Silence. It's all around these guys and yet...he swears a few of them never learned the meaning of the word or even the concept of.
Still, they were his friends and friends meant company.
On the other hand he was no idiot. Shinso knew he was their friend because of his connections to Midoryia. If he did something to hurt that connection, or Heaven forbade, hurt him-He was going to be in a world of pain.
It's almost funny, how unbelievably easy it is to just die in this world. He doesn't know how anyone is still alive.
They may be his buddies, but never think for a second that Shinso doesn't forget what they truly are.
Monsters.
And they will kill him if they feel it's necessary. If they lose interest in him. If they feel threatened by him. If he says or does or Hell, even reacts in the 'wrong' way. He'll be killed or eaten. Perhaps torn apart. It's a possibility, it's always a possibility.
