Can't stop won't stop making OCs

I briefly talked about these dudes (the first 4 at least) in a comment once and finally I could put my very strained relationship to art aside for a while to properly draw them out. First 4 are a group, consisting of Samyan, Kikuko, Hirohito and Tatsuya, last 2 are their rivals, half-ukrainian twins called Viktoryia and Maxim. More info in the comments so I won't clog the feed.
