Momo's fairy partner is the female ninja muglox Yamane, who admires Yatch and engages in ninja training. Yamane utilizes a bird whistle as her magical tool. Momo formed this partnership approximately halfway through the second season, integrating her into the main fairy storyline.

She employs Hoshino as her butler, whose role parallels that of Kaoru's butler Hirai. Hoshino and Hirai share a professional rivalry, occasionally demonstrating mutual affection. Momo debuted in Episode 68, where her initial antagonistic actions stemmed from jealousy toward Kaede.
