Invincible twice over
In the project, there is at one end the protean "be-water-my-friend"ness of Takahashi Ai, and at the other the one-dimensional supercharacters of the fourth generation. Though most idols beyond the girl-next-door will find themselves leaning one way or the other, few reach either extreme. Matsuura began a gradual migration, but has gone missing of late.
Tsugunaga, however, traverses the poles with aplomb. Much of this has to do with her voice. In more pocket-sized and pithy terms, witness the lines (from consecutive singles, no less)--
ね いいでしょ? (tsukiatteru noni kataomoi) and
ハランがバンジョー (jyanakya mottainai).
