What are Walter Staff?

They are staff members who act as playmates for everyone at Walter Park, especially those in trouble. ──
On the surface, Walter Park is a fun place, but it was originally built as a facility for demons in their Evil Cycle to release stress. Because of this, dangerous areas still exist if you go too deep. Example: Kararagi Street ─────────
