For comedic effect, watch Dan show up next chapter, and be braindead enough to be immune to the power, but still does whatever she wants because she's a woman.
Though he did supposedly get a girlfriend, though I almost kind of want to bank on her being the "girlfriend" (like if she got out earlier and he was her test target.)
Well, we already knew that the hero belt doesn't offer charm resistance, otherwise our boy wouldn't have had so much problems with Mira's second form. A charm user, like mother like daughter. Oyakodon incoming for Haru?
Also seeing as her ability is captivation, I lowkey bet my nutsack that he's gonna snap out of it because Mira transforms back and he's overwhelmed by the cuteness or smth.
...yeah that belt didn't seem to help at all. Why NOT just give it to Mira's dad and have him do science on it so everyone can get to benefit if it can't actually stop the mindcontrol?
