I can’t tell if Kagari is really helping or if she‘s actually making things worse
It might also just be that it gets worse as Ageha gets older, in which case keeping Kagari around is probably a good idea
In other news, I guess Ageha drew the short end of the stick; most people who can see ghosts get the power to fight them, and then we get stuff like Bleach and Jujutsu Kaisen
Ageha just gets a spooky ghost wife, which I guess isn’t that much worse
