Kiazuki's Moon is an infertile moon that Kiazuki used to protect until it was destroyed by the Big Bad. Kiazuki traveled from her moon to Hanazuki's Moon in order to know more about growing Treasure Trees. It is currently unknown what the moon looked like before being in ruins. Kiazuki has mentioned in Friend or Foe that there are Mazzadrils inhabiting the moon.
On it, Kiazuki has a growing pile of dormant treasures that Little Dreamer gave her.
- The moon's appearance before being struck by the Big Bad was possibly revealed in "Recovery", because red (Kiyoshi) and blue (Maroshi) were the only members seen to fly to the moon, but Green (Kiazuki) was already present seemingly upon arrival.
