I've said it before and I'll say it again: Mai likes burning himself. It's pretty faint here but you can see the line of discoloration on his arm where he pressed an iron into his arm. Why did he do this you ask?
Well, because he felt like it. Actually, he felt like making a happy face with the pointed end of the iron, the line on his arm that you can see here was the smiling mouth of his iron-face, with the eyes above it having faded over the last few years..
