Kemoteto Yakuza project is the direct spin-off of the cancelled PanelTetro project, made by the same artist kbh_kazuhisa

collectively ''Kemoteto Yakuza'' is a gang of 4 inner-criminals with some badass-looking, as the main characters are Kazuhisa, Reddy, Takayama, and Hideki, also for some reason they have much rivaly with The Bad Guys gang, making them located in Shibuya, Tokyo (Japan) counterparts

and yep, they are much efficient than them(?)
