- Pariston: Hiroki Takahashi (Actually Hisoka in the 99 version) - Cheadle: Ikue Ôtani. (Pikachu, Tony Tony Chopper) - Alluka: Maaya Uchida. (Takanashi Rikka in Chu2Koi, Amatsuka Mao in GJ-bu! Iki Hiyori in Noragami) - Mizaistom: Akio Ôtsuka. - Piyon: Tomoka Kiriyama. - Kanzai: Ryôta Ôsaka. - Tsubone: Ikuko Tani. - Amane: Marina Inoue. - Kaito: Uki Satake. (Actually she voiced Podungo Lapoy, one of Kaito's friends, it's the one with dark skin, white hair and she's also really tiny. Also she did QT in Space Dandy)

I don't know about the rest because I don't even remember who they are, but the four I just mentioned are really good choices, especially Alluka and Pariston.
