It's Kedamono and Onomadek from the 3d children's anime Popee the Performer! These characters didn't have a ton of images on E621, but they're fairly popular anthro characters outside of there. I also used a few show screenshots and pieces of official merch.

Trained using Fluffypony Mix as a base. Their mask design is tagged as 'noh mask'

Recommended reinforcement tags for both:

solo, anthro, wolf, noh mask, shorts, white pawpads, tail

Recommended reinforcement tags for Kedamono:

male, purple fur, orange shorts

Recommended reinforcement tags for Onomadek:

pink fur, red shorts, striped shorts

Note: Onomadek's canonical gender is ambiguous, and so fanart depicts them as male or female interchangeably. Use a gender tag if you want to specify!

Specify tags such as 'official art' and '3d' if you want a more canon accurate look!
