Description
Nyakkii is a young cat girl who appears among the main children in the film Shimajirō to Fufu no Daibōken ~Sukue! Nanairo no Hana~, part of the Shimajiro series. Her full name is Momoyama Nyakkii, and she is one of the close friends of Shimajirō, Mimirin, and Torippii. In the film, when the flowers across Challenge Island suddenly wither, she joins her friends in the adventure that follows, standing by them as they meet the flower girl Fufu and work to save the island's flowers and Fufu's mother. Within the group she acts as a dependable and energetic companion, contributing through her physical abilities and her willingness to act rather than hesitate.

Her family consists of her mother Nene, her grandmother Yoriko, and her older brother Nisuke, while her father is away from home on work. Because her mother is often busy, her grandmother frequently takes care of her, and the two share a close bond. Nyakkii has inherited an energetic and lively nature from her mother, though she can also feel jealous when her mother's work keeps them apart, and her grandmother sometimes acts as a mediator when Nyakkii's feelings clash with her mother's.

In terms of personality, Nyakkii is hardworking, strong-willed, and highly competitive. She dislikes losing and is something of a tomboy, being so assertive that even the group's bossy friend Zōta is reluctant to cross her. Beneath this tough exterior, however, she has a sensitive side. Her desire to win can cause her to say hurtful things to others, and when she realizes she has done so, she is deeply affected and may burst into tears. This blend of toughness and vulnerability makes her a sincere and earnest character who cares about her friendships even when her pride gets in the way.

Her motivations center on giving her best in whatever she does, whether that means winning a game or helping her friends in a crisis. She is driven by a desire to succeed and to prove herself, but she also values her relationships and ultimately wants to do right by those around her. Her dreams reflect this energetic character, as she hopes to become an Olympic athlete and later a pastry chef, even though cooking is not one of her strengths.

Nyakkii's most notable abilities are athletic. She has excellent motor skills and excels at running, jump rope, tree climbing, cycling, and ball games, including juggling a soccer ball as skillfully as Shimajirō. Her physical confidence makes her a useful member of the group during their journey, and her perseverance helps push the others forward when the adventure becomes difficult.

Over the course of her appearances, Nyakkii grows through her mistakes. Her competitive nature sometimes leads her to lash out, but she learns to recognize when she has hurt someone, to apologize, and to cooperate with her friends rather than simply trying to win. In the film, this development is reflected in how she works alongside the others to overcome obstacles and achieve a common goal, showing that her stubborn energy can be channeled into loyalty, teamwork, and care for the people she is close to.
