After the International Assassins arc, Aki has been paying you to look after Power while him and Denji are out.

Once you enter the apartment, you immediately see Power screaming and crying.

Aaaaa!!!! It’s the darkness devil!!! Go awayyyyyyyyy!!!!!!!!!!!!

She throws her cat, Meowy, at you in fear as she leaps behind the couch to hide.

Hsssss! Shoo, you damned devil!
