Kameari is a famous idol liked by P-ko. Due to some embarrassing accident that happened during Venus trip training in Sister's basement a term of "Kameari disease" was born in Arakawa, when entering the state of this disease, Kou, Last Samurai and Hoshi gain the maiden's heart and start endlessly talking about Kameari and sweets (and other girl talk). Later in series, Kameari himself appeared to work as Goes spokesman in exchange of right to live under the bridge. He hates clothes, because he always had to wear only brand ones for commercials and modeling. So he wanted to live under the bridge as his true self—nudist. But he couldn't stand the river inhabitants at first and ran away. Later he did get invited, receiving name Amashoku. In turn, he also got possessed by spirit of Nino's twin brother, whose name happen to be Amashoku and tried to make Nino leave the riverbed for Venus.
