Why the hell did teenage me buy into the dumbass rumor that Mahiro from Kiryu was a middle schooler in Curse and MADARA? What pre-teen lets Yuuga write him a song themed around Nakadashi (I don't think I should have to explain what that is lmao)
In your defense, a lot of bandmen do start super young (e.g. La'Mule's drummer was 16 when he joined), but I think middle school (12~14) is probably way too young to be even allowed to be taken out of school.
I actually sat down and tried to figure this out with a hardcore Hina fan. We deducted if he was 14 in Madara, he'd be around 38ish. I understand asians don't age, but this is genuinely confusing...!
