Real name: Yachiyo Tsukimi. The administrator of Tsukuyomi. She has 200 million fans. She loves Iroha but tries her best not to let her true identity be discovered. She is actually Kaguya from 8,000 years in the future, a secret she keeps from everyone. The reason two Kaguyas exist in the year 2030 is that she time-slipped from 2030 to 8,000 years in the past and lived through the ages. If her identity is revealed, Kaguya might not return to the moon, causing Yachiyo's existence to vanish, so she never calls herself Kaguya.
