:)) Its true hahahah I play with the name every time saying that the song is about a skunk

Hitoka, Hiyori, Mako

I've got all 4 audio songs from single and have listened. Most of them disappointed. Especially song of Sugiyama (Seishun Anthem), expecting much more from him. The song is much more boring than anything that he wrote for Ebichu. Sekigae no Uta is not bad but not amasing. Throughout the song still expect that here it would rise to a higher level of interestingness, but not, it remains at the same level, unfortunately. Iza, Yamato Nadeshiko seems the most interesting song on the single, and in general in their repertoire, I might even listen to it several times, but no more

In general, it is my favorite single of Tokisen now, although very, very average

I like Tokisen much more as models and actresses than as a musical group yet (2shots are the best)

Yes. Tokisen's 2shots is sugoi cool!

Hitochan is unforgettable with glasses
