Ayumu

Ayumu's seen some shit, and as a result can see and interact with ghosts, gone selectively mute, and is generally non-expressive save subtle changes. He has a tendency to keep to himself as it can take him an exceptionally long time to grow comfortable enough with new people and situations to verbally communicate. He's slowly working on dealing with his selective mutism with a little help from friendly spirits he encounters since the dead feel much less threatening to him than the living.
