ah yess, chuunibyou MC like manga Kage no Jitsuryokusha or Konosuba. but MC's personality is like manga Jibun no koto o shujinkouda to shinjite yamanai, pretending to look cool on the outside, but actually being really lame inside welp, for sure, sooner or later MC will end up becoming overpowered
Definitely one of the more entertaining "chuuni" satires I've seen. It's difficult to run with the premise for too long, though. Sure, there's enough tropes to work with, but you'll have to get clever with the meta to keep reader interest. Hoping to see some weird, unconvential ways his delusions both help and hurt the situation.
This has at least 5 layers on it. He thinks he's strong but he's painfully aware that he's mediocre, and he's ACTUALLY mediocre, but because of his own self awareness he's actually pretty good himself.
Difference between this cringe lord and Cid is that Cid doesn't need plot armor to continue his larping. This guy does. First guy to fact check his "toughness" will just kill him (remember the guards who interrogated Cid than tried to kill him? Put this guy instead) which means he will need to have the biggest plot armor imaginable (aka bad writing) going forward or this story won't even last 5 chapters.
