>>3552578>>3490856I still think that Polka looked best that one time she got a tail. It gives her model a balance to her hat, as well as making her silhouette closer to her. I know the OP says that it glitches out turning white instead of brown sometimes, but... do anyone really care? I even think that her tail sometimes being of another color adds another funny layer to her character. It should comeback, at least some times.
Touching this subject, I think a little polish to all models could do a lot of good. Towa for example, could get her tail; Choco have one and it looks pretty good. It's very close to her own. It ties them up as the only demons of the cast.
Bonus/extra costumes would bring some hype, even if little. Watame samurai, or Watame Witch would make the crowd scream. Couple it with a good BGM and you have gold on the fight. Rushia Rosada it's also a very distinctive costume that could be added.
About new characters... at this point OP limiting himself to one per week could keep the flame going. We have: Ankimo, Listener-san, Miofa, Loli-Chama/RedHeart... plenty to pick from, before the Holostars invasion.
