An idea I had is to have Syahata loses all her weapons. Then she goes into a supermarket and has to use things from the supermarket such as ( A broom for melee , soup cans and other things she can throw then pick up). She would get all her weapons back after the area.
The enemies that would be there are a mother like enemy ( she could summon smaller enemies that would attack for her.)
Another enemy that has no relation to my last paragraph could be a frog that has a 🅿️enis as a tongue
