Twelve years old tabaxi child that works inside the underground Horn Blu market, offering a fast pay-what-you-want news delivery service. He's really sweet and friendly, and tries his best.

Mru came up with the idea of this business and put in practice himself, and adores his job. However, his aunt procured him a secret item that helps him be unbelievably fast in his mail delivery.

He lives in The Clowder with his aunt Mein Coin, a urban center developed in height very close to the Horn Blu Mountain, that the tabaxi share peacefully with ratfolk.

Mru has a rat plushie named Mini Tziú. The stuffed toy is named after his best friend, a ratfolk girl of the same age that in turn has a stuffed cat toy named Mini Mru after him.
