Seiyuu tagged, missing a "few" roles I don't know.

Added "sphere_(band)" tag since all four seiyuus involved are members of that said band.

I added:
Murasame_Sumika from Sasameki_Koto.
Feldt_Grace from Gundam_00.
Kunieda_Aoi from Beelzebub_(Manga).
Yamanobe_Tomo from Seikon_no_Qwaser.
Ferris_eris from Densetsu_no_Yuusha_no_Densetsu.
Hiiragi from Hanamaru_Youchien.
Yuuki_Asuna from Sword_Art_Online.

Also added the Character_Request tag.

I added:
Fam_Fan_Fan from Last_Exile:_Ginyoku_no_Fam

There, finally identified all characters and annotated them, color-coded to identify which voices which.

Final additions include:
Manyuu Chifusa of Manyuu Hikenchou
Jinguuji Yako of Chuu-Bra!!
Asuka Hizuru of Towa no Quon
Corticarte Apa Laranges of Shinkyoku Soukai Polyphonica
Marui Hitoha of Mitsudomoe
Isurugi Noe of True Tears
Arrester Blanket of Fight Ippatsu! Juuden-chan!!
and Marui Mitsuba of Mitsudomoe

And with that the character request tag has served its purpose and hereby removed.
