Cat's Daily Quests:
[Hide-and-Seek: Hide in Takanashi Toka's house for at least one hour. (The timer starts when the target is home and stops when they leave.)]
[Unplug the Internet: Make Gabriel lose her internet connection at least five times within 24 hours. (Her computer must be in a game.)]
[Kidnap the Hamster: Steal the hamster from Doma Umaru's room and demand a ransom. (The bigger the ransom, the greater the reward.)]
[Pineapple Bun: Steal Satanichia's pineapple bun. (Double the reward if you unwrap it and eat it in front of her.)]
Mo Bai hid in the room, two hamsters tied up with his tail. He held a pineapple bun with a few bites taken out of it in one paw, and pressed down on a signal jammer with the other. As Takanashi Toka searched everywhere for a cat, holding a soup ladle and covering her mouth and nose, he looked utterly innocent.

"What bad intentions could a little cat possibly have?"
Slice-of-life worlds included: Gabriel DropOut, Love, Chunibyo & Other Delusions, Himouto! Umaru-chan, Miss Kobayashi's Dragon Maid, Aho-Girl, Dropkick on My Devil!, and so on. (There'll basically be a bit of every slice-of-life anime.)
The protagonist is a spirit (Luo Xiaohei). He'll occasionally visit other worlds to hang out with nonhuman characters like Puck, Kumoko, Nezuko, and Fushi. (These may get their own side stories.)
