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, tailRecommended reinforcement tags for Kedamono:
male, purple fur, orange shortsRecommended reinforcement tags for Onomadek:
pink fur, red shorts, striped shortsNote: 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!
