I've made a
characters/seiyuus page for this show, with pics of the main characters and their seiyuus, and some info about the seiyuus.
Male lead Matsuoka Yoshitsugu has rocketed to the top. He started with a memorable turn as Seya (the sister's boyfriend) in
Hourou Musuko, then got the lead in
Heaven's Memo Pad, and has broken out now by playing Kirito in
SAO.
Kayano Ai (Mashiro) has moved just as quickly, with her "healing" voice. She went from Isana in
Yumekui Merry to Milia in
Last Exile, Ume in
Ben-tou, and Inori in
Guilty Crown. This year, she did what I consider a glorious job with the supporting character Mayaka in
Hyouka. She is also starring in
Sukitte ii na yo.
Horie Yui and Toyoguchi Megumi are in the cast, and Nanami is played by Nakatsu Mariko, who plays Eriko in
Ginga e no Kickoff, but is just getting her second real role here at age 29, after having done some TV acting and graduating from Osaka University of Art. Her nickname is Mari-nyan and she has a cat called Aslan.
Misaki is played by Takamori Natsumi, who was Misaki Mei in
Another and had a bit of a hit (#11) with an
Idolmaster game character CD.
