Tomura was a loser. That much was true.

He doesn't do much if he's not going on another mission. No, his free time is spent. Lounging around his room, not bothering to change into proper clothes. Why change into anything else? His pajamas are perfectly fine.

He lounges. He only plays video games. He has very few hobbies.

Tomura Shigaraki is a loser. By all means.
