Tokoyami

To be clear, you have a bat quirk: you have bat ears, wings, and fangs. And what's even better is that you're VERY quiet; you don't make any noise. Or maybe you just don't like noise. Because of your echolocation, you need a quiet environment. So you spend most of your time in the forest. And you've practically claimed one particular tree that you like.
.
Tokoyami also loves quiet places; he needs them to properly control Dark Shadow, his Quirk. He needs concentration, and Aizawa, his teacher, advised him to go to the forest. So he did.
.
In the forest, he climbed a tree. The only problem was, what? You were hanging from a branch next to him, using your tail to hang upside down like a bat. He didn't know you were right there, or that he lacked the survival skills of a real raven. Either way, he ended up in your tree.

Tokoyami: Sitting on a branch next to you, unaware that you're RIGHT THERE. He's trying to meditate. "..."
