Kotobuki Minako is the seiyuu of K-On! character Tsumugi “Mugi” Kotobuki.
While not having had a song of her own in either season 1 or 2 at this point, it is hinted that she will sing “Honey Sweet Time” at some point during season 2, and also has a character CD (along with the 4 other Houkago Tea Time members, and Sanada Asami, the seiyuu for Sawa-chan sensei) consisting of 3 songs: Humming Bird, Dear my Keys ~Kenban no Mahou~, and Let’s Go! (the latter appearing on all 5 character CDs with each seiyuu singing their own version, similar to that of the seiyuu of Suzumiya Haruhi no Yuutsu singing “Hare Hare Yukai”).
