...After an unexpected fight, the Imaginary Crew ends up inside a newly-opened club. But little is known to anyone outside the Crew about what is hidden underneath...
Just in case if anyone's wondering about the colorful character, I'll leave this block of text here, especially since the guy that I originally tried to reply had his inbox filled up, preventing him from getting the message. Might as well spread the words:
: Rainbow Dash?
Well, almost. The character's name is "Spectral", and the names of all three guys of the Imaginary Crew (main characters) may be fully revealed soon. On a not so related note, I had been lately contemplating an intro for the Dokuroshima series which is possibly where it would happen as part of the visuals, kinda like in K-On (except with metal/punk-ish music in the background).
As for the character's design, it is, indeed, heavily influenced by Rainbow Dash (and perhaps a bit from other, non-MLP characters), but during future installments, due to character development, his design will slightly deviate from that.
