Here's a fact about Mob Psycho 100 that has been confirmed by multiple sources

Kameda draws Reigen butt-first

first he draws the butt, then the back, then just expands outwards from there

... im shocked but not surprised.

for any new mp100 fans, it is 100% true, got to see it with my own eyes at his CRX 2019 drawing panel

...I was planning on rewatching mob sometime anyway but now I feel like I need to check how often the composition has reigen facing away from the 'camera' unnecessarily

gotta check if the butts match
