Quirk explained:

Quirk name

Dark

When she wants to, Kiki can summon these soulless entities. They do anything at her command. They are powerful and can be spawned at multiple times. She has her quirk under control but sometimes it becomes too much for her to handle and messes with her head. (the entities like to mess with her feelings and thoughts)

Overall, I'd say that from a 1-10 her quirk power is a 7.5
