and why is it Hiro?
Makoto from Shool Days takes my vote. I got the series recommended and did not enjoy it at all but pushed through because I was promised the pay off would be worth it. By the time ‘stuff’ happened I honestly felt like he deserved it and was just glad it was over.
Other than that, Yukiteru from Mirai Nikki was pretty bad too. And most controversal, I disliked Mikado from Durarara - he was good in the beginning, but he peaked during the first Dollars meeting where he send the mail to everyone. After that, it was just downhill for him.
Mirai Nikki is much better if you think of Yukki as a minor side character that happens to be the motivation for the actual main character.
His character makes sense, but it isn’t interesting. So trying to give him the mindspace of an mc is just an exercise in disappointment.
