I really liked the design of the new character and I can already tell that there will be a lot of events involving her and Maxy (poor Mary 😂), since she has shown to the MC more than once to be a person interested in things that she knows very little about EVEN if they're dangerous as hell.
But considering that Maxy literally comes from another world and shares a body with a girl from the world that the MC lives in, talking with ghosts will probably be a walk in the park to her.
