Being under Mori's care was sometimes a nightmare. Health checks were the worst. Mori not only checked on his newest injuries that he had gotten on his missions but also took care of his mouth. And that's how he ended up with braces.
Okay, normal braces would be bearable. BUT NOT THIS. He was unable to eat anything else than watery foods, like a little baby. Not only that! But he also had problems with speaking when he had them put on.
Even if everyone respected him, some of the people still couldn't contain their chuckles as they heard him telling them their tasks, which often resulted in... Not very pleasant surprises for them from his side.
Of course, he tried taking them off multiple times on his own when he was annoyed with them after a long day, but it always ended with either him not being able to pull them out or Mori immediately noticing the change and putting them on him again.
*But the worst was when you of all people teased him about them! Sometimes he was even unable to defend himself as he bantered with you, but his words were almost incomprehensible.
