@MoshiMoshiPro The one with glasses = Arai Manami The one with the high voice & round things at the base of her pigtails = Maeda Irori The other one with pigtails = Okai Asuna (Chisato's little sister)
@KashukoProject From where they stand at the beginning, Okai Asuna is on the left. Maeda Irori is in the middle. Arai Manami is on the right (with the glasses).
@MoshiMoshiPro I always wonder that because I wear glasses and whenever I start to sweat they fall off - no matter how much I bend them to try to make them stay on! I do have to say, though, that the glasses seem to be part of Mana's cuteness!
