Meinya

Race: Meinastoirim

Meinya is Prushka's pet given to her as a present from her adoptive father, Bondrewd, as her 10th birthday present. Its name is a result of Prushka not being able to pronounce "Meinastilim" when it was given to her.

Meinya later joins Reg, Riko, and Nanachi on their adventure to the bottom of the Abyss.

Meinya is a rabbit-sized creature called a Meinastilim, also known as a child of change. It has an oval-shaped body, stubby legs and feet, and large ears it uses to fly with. Its face is somewhat resemblant of a toad's as its pupils are slitted horizontally across the entire diameter of the eye. By sniffing Meinya's fur, Riko and Prushka can navigate Ido Front without succumbing to the Curse.

During Reg and Bondrewd's fight, Bondrewd ejects several of his cartridges and begins to recite their names. Meinya interrupts him, running to one cartridge and, after sniffing and licking the contents, wailing over it. Bondrewd confirms that this cartridge contained Prushka.
