Haruka Kaminogi's theme is Subarashiki Sekai (Wonderful World) performed by eufonius. They performed the opening theme, Idea, to her series, Noein. I chose that because Haruka's seiyuu, Haruka Kudo, did not do any image songs for her in Noein. Although, she does sing, and has image songs for some of her other characters in different series. Listen to it here.
Sora Takenouchi's theme is Sora Iro no Kaze (Sky-Blue Wind) performed by her seiyuu, the late, Yuko Mizutani. Listen to it here.
Tamao Tamamura's theme is Hana Hoshi Sora (Flower Star Sky) performed by her seiyuu, Nana Mizuki. Listen to it here.
Erika Amazake's theme is Yappari Kimi ga Suki! (Still, I Love You!) performed by her seiyuu, Eri Sendai. That's the ending theme to the Japanese version of her series, Medabots. Listen to it here.
Hime Utsumiya's theme is In My Dream performed by Eri Shingyoji. That's the opening theme to her series, Brain Powerd. Hime's seiyuu, Akino Murata, apparently does not sing. Listen to it here.
Nayuta Moriyama's theme is TAKE performed by her seiyuu, Romi Park. That's the opening theme to her series, Shingu, and it was originally performed by singer, KAKO, but Romi did her own version of it on a special CD. Listen to the KAKO version here.
Frances's theme is Hikaru Michi (The Shining Road) performed by Aya Hiroshige. That's one of the ending themes to her series, Sonic X. Frances's seiyuu, Yuka Shioyama, apparently does not sing either. Listen to it here.
Sarah Goodman's theme is Kirakira (Glitter) performed by Manabi Mizuno. That's the 2nd ending theme for the Japanese version of her series, Flint the Time Detective. Sarah's seiyuu, Nana Mizuki, is a singer, and she did sing as Sarah in a couple of songs in the series, but not alone. I could have chosen one of Nana's many other songs, but because she has the same seiyuu as Tamao, I decided to switch it up a little. On top of that, in the ending animation for Kirakira, Sarah is centrally featured, so I thought it was a perfect fit. Listen and watch it here.
As always, remember to have fun with this, and choose the best themes for your club members. Happy Holidays everyone!
