Mr. Micchi, also known as Mr. Mitchi, instructs dance at Dream School. His slim frame features light cream skin, wavy blue hair, green eyes, pink cheeks, and a light orange beak. He wears a dark blue suit with a red belt and red boots, occasionally opting for dresses or skirts.

Combining strict teaching methods with emotional sensitivity, he demands perfection in dance lessons and corrects mistakes promptly. Yet he displays pronounced romantic tendencies, often tearfully reminiscing about an unnamed "darling." His effeminate mannerisms include using the feminine pronoun "atashi" and feminine speech patterns.

In *Tamagotchi! Yume Kira Dream*, he initially critiques Yumemitchi and Kiraritchi’s dancing skills but invests deeply in their progress. He grows emotional witnessing Tropicatchi master a "courtship dance" for Kujack Jack, seeing his youthful passion mirrored in her. As a Dream Festival judge, he fails to recognize Yumemitchi and Kiraritchi post-transformation but later acknowledges their improved performance abilities.

Across Tamagotchi releases, he consistently serves as a dance instructor. On Tamagotchi P’s, he appears during Dream School classes. In Tamagotchi 4U/4U+, he leads the park’s Dance★Game minigame for weight loss. Tamagotchi m!x (Dream version) features him in Dance♪Session with Miraitchi and Clulutchi, plus random Dream School visits. For Tamagotchi Uni, he exclusively teaches Performance Class at DoriTama School, observing Octodogtchi, Knighttchi, and the user’s Tamagotchi.

In *Tamagotchi no Doki Doki Dream Omisetchi*, he operates the Election Center where players support manifestos; implemented winning proposals upgrade the town.
