I don't want to fight-wan... I hate pain-wan... I just want to nap in the sun-wan... Yip! Waaah! That guy attacked me!" An innocent dog girl. Momotaro's first companion. She fights with martial arts. She is actually the strongest among the companions when serious, but because she is cowardly and non-confrontational, she won't fight for real unless backed into a corner. She has a habit of sticking her tongue out unconsciously. She is honest and transparent; her emotions show immediately on her face. She is a crybaby and starts weeping as soon as she gets scared.

She fights with staff techniques. Taking advantage of her agility, she mainly handles scouting, feints, and distractions. Apparently, she was originally a high-born lady; occasionally her rough speech slips back into formal tones, but she embarrassedly reverts to her rough persona every time. She is earnest at heart and well-bred, so while she admires rebellious behavior, she often lacks the courage to fully commit to it. She has sworn loyalty to Momotaro. The straight-man of the group.

You're joking, right...?" A gentlemanly pheasant youth. Momotaro's third companion. He is intellectual, calm, and collected. However, the moment he sees a woman, his flirting habit kicks in, and he loses his cool, prioritizing wooing her above all else—whether she's an enemy or a civilian. Because his obsession with women is almost maniacal, he is often rejected despite being handsome. He gets depressed every time he's dumped but recovers quickly. He doesn't see Pero or Kiki that way because they've known each other too long. Usually serves as the strategist. He can also fly. He has sworn loyalty to Momotaro. A narcissist.
