The chuunibyou is strong with this one.
To be fair, when I was a kid I was obsessed with stealth too... but I wanted to be a hunter, not some secret justice-monkey. I used to have dreams of vanishing from the world to live in the wild places alone and killing anyone who strayed too far into my territory unbidden...
... but I was born in a REALLY bad country for that sort of thing. So yeah. That idea went down in flames. Now I'm an urban hermit instead of a proper hermit.
