you mean fuu-chan's dad? didn't he die?
No, he's a different person and yes he did. Fuu-chan is Futatsugi. Yotsuha's friend. We haven't see Yotsuha's dad yet.
Do you want spoilers? Because we do now
No thank you, I'll wait.
Okayy
It makes my blood boil. It's been awhile. I like stories like this but I gotta read them sparingly. The mastermind hasn't been revealed but it's definitely Yotsuha's dad. In some way, for some reason, her and Uichi ruined his life or whatever fantasy he curated for himself. He used the watch to go back in time to destroy them. His one mistake so far was losing the watch and Yotsuha finding it. I don't know if Mitsuha actually knows of the watch's power but he has seen enough of Yotsuha's dad to know he is a dangerous demon, even more than their mother. Praying for Uichi, Yotsuha, Futatsugi, and Mitsuha's happiness. They deserve it. I hope they get him. And end him. He at least needs to die. Please author.
