He was stalked by someone who hurt Mafu both physically and mentally. That's why Mafu kinda has depression, but he's coping better with it nowadays. But he can be pretty moody and revert to someone quite gloomy as seen in his tweets and in his namahousous, like in his Hikikomoronai Radio eps with Soraru.

He was often bullied during childhood by others. We don't know the true reason behind the bullying, but it's pretty personal to Mafu anyhow.

But he has great friends, like Amatsuki, Luz, Urata, and especially Soraru, who helped him in the past during that time. Like seriously, Mafu said something about Soraru standing up to the culprit who caused 'the incident' and made that stalker promise not to hurt Mafu ever again. Now the two of them are pretty close ever since then.
