Atsuhiro Sako AKA Mr. Compress, member of the League of Villains and snazzy dresser. He’s helpful. He’s powerful. But, why is he a villain? Well, it looks like we won’t learn Mr. Compress’ true motivations anytime soon in the manga, but why let that stop us? Let’s take what we know about our favorite marble master and come up with some theories on why exactly Mr. Compress is a villain.
First things first, it was never stated Mr. Compress admired the hero killer, Stain. So, we can assume he joined the League under different circumstances. Next, Mr. Compress is a showman. He loves showing off and seems to be at home performing for an audience. Another clue could be him wearing a mask. Sure, the police know his identity now, but either he was trying to keep it a secret in the beginning or the mask is part of his act. You know, I’d say it’s a little of both. The mask is part of his act and he also wanted to keep his true identity a secret. If true, that means Mr. Compress was a well-known figure, either on a national or local level.
We also know Mr. Compress is well versed in using his quirk. He knows its limits and when best to use it to catch people off-guard. And, while we don’t know his official age, Mr. Compress carries himself and talks to the younger Leaguers like he’s a seasoned professional. Based on that, I’d say he’s over 30 years old.
