KiracCHU is a small, pastel pink mouse-like mascot with a minimalist, drawn-style black face and blushing pink cheeks. A yellow star is positioned over her face, while pastel blue stars adorn each ear. Her curled tail and matching pastel blue bow-tie, which is fastened with a pink heart-shaped gem, complete her signature look.

In her Pretty Mascot Form, KiracCHU transforms into a humanoid version of herself. She has gold eyes with long, curled lashes and star-shaped pupils, enhancing her magical appearance. Her bubblegum pink hair is styled into fluffy twin buns, each decorated with a pastel blue star. She wears a pastel pink dress featuring a white star print along the hem, finished with scalloped pastel blue lining. The top of her dress is white, accented with a pastel yellow star on the chest, and a pastel blue bow with a heart at the center adorns her neckline. Her look is completed with pink shoes, white bloomers, and her signature curled tail, which remains in this form.

In her Idol Mascot Form, KiracCHU retains the eyes and facial features of her Pretty Mascot Form, but her hair becomes more detailed, with curled locks extending from beneath each bun. The stars on her buns are replaced with a pastel blue head bow, trimmed with pastel yellow frills and centered with a pink heart. Her tail becomes more elaborate, curling into a heart shape with a star at the tip. She also gains a pair of blue star earrings and a set of soft, pale-colored wings, adding to her idol-like elegance.

KiracCHU is a friendly and supportive mascot with a bright and endearing disposition. She is deeply loyal to her team, Miracle☆Kiratts, and always strives to assist and uplift those around her. Although she is prone to becoming easily worried, especially when things go wrong, she never allows fear or uncertainty to stop her. Instead, she remains optimistic, encouraging, and determined to help in any way she can, making her a reliable companion and an emotional anchor for her team.
