The "actually there should be 4 victims" still bothers me a lot. The end of this arc hinted that Yoshie (ayano's and yuzuki's mother) could be the mastermind behind all recent katabuchi's "event". Because if it's true then the reason she asked yuzuki to reunite with her sister is to be the fourth victim right? since she also has branch family blood in her and the cursed child is still below 13 years old (I think). Also Yoshie's cry at the end can be implied that she's sorry to send yuzuki to be the fourth victim. Please someone tell me if I missed something. Or maybe I'm just thinking my as off because it was showed they all lived happily. Damn this manga hella good.
