, who's basically a Tsugaru counter part. Fans have given him a shy, timid personality. He also has second personality named Nanashi who's sometimes seen wearing a purple yukata. He's depicted as Sakuraya's other self who's more darker. None the less they're both the same person just different personalities. The image is from Yasuda’s artbook

P-420 (Psychedelic 420)
was basically the prototype to Delic, later fans further developed him by drawing him with firearms.
Fans created a blue version of P-420 named V-420 (Virus-420)
Who's basically an anti-form of P-420 or Virus 138's match.
Vi is v-138 (virus-13 cool

Other then that they're not known as popular because they're both pretty much fanbased and sadly that's all I know about them.
