Happy Halloween! God this was so long to draw... So you I don't think you know most of these guys, so from left to right (on the ground XD):
-Dimitri, he's a vampire, no costume
-Clingy Venus and Mars, planets, they're just dressed for a classy evening or somethin'...
-Sabrina, neko, dressed as Mina(Dracula), I did my best XP
-Kai, neko, dressed as Dracula...
-Neptune, planet, has accessories of Neptune the god (probably convinced by Moon)
-Taro, star, no costume but has Phamda, his mutant Fly trap who actually eats birds
-Sun, well, the sun, messing in his sister's hair
-Moon, the moon, wearing bunny ears
-Earth, planet, has a witch hat
-Pluto, ex-planet, one belt to look crazy.
Left to right(ceiling)
-Jake, kitsune, stalking Kai as always
-Uranus, planet, no costume, he's an assassin because all the anger he stocked up from being teased (his name is Uranus, c'mon) pushed him to do so.
Yeah, so that's it, all of these guys wishing you a happy Halloween, except maybe Uranus, but hey. Now, goodnight.
