Goblin Slayers is literally weaponized-autism in a fantasy setting, I am dead-serious about it.

The dude's life revolve about one very specific hobby that other peoples find weird at best, downright insane at worst, but he is just so so god damn good at it. He has literally zero-social skills, wouldn't be able to flirt or notice someone flirting with him if his life depended on it, probably wet-dream about killing goblins and the rare time he bother talking to peoples is always about something related to slaying goblins. Even his fucking name his just indicating of what his obsession is.

Goblin Slayer is a very rare case of an absolute sperge, spagethi-spilling social weirdo of a character being a complete badass despite (or rather, because) of it.
