Moon shrine 2 Volume 9 (explanation)

This is the holy temple that the [Moon Rabbit] from buddhist lore was invited to. The authorities of the moon are divided into 15 parts, and it's a game board type gift that can be summoned by a [Moon Rabbit] with more than one authority of the moon.
Inside there’s a barrier maintains similar environmental conditions (gravity, oxygen, etc) as on earth, but the ON and OFF of the barrier is determined by the summoner. If the opponent is a human, Kuro Usagi can use this single Gift to easily defeat them. The authority of the moon isn’t for show you know.
