Tsurugi Okachimachi serves as a Prism Star at Schwarz Rose academy, performing in the unit The Shuffle. His appearance presents bright lilac hair tied back on each side, olive green eyes, and a black spade-shaped face paint accenting his right cheek. Standing 168 cm tall, he embodies the "cute" style designated to him.

Tsurugi maintains a deliberate dual nature, adopting a feminine persona and modulated voice to align with this style. This crafted performance starkly contrasts his authentic self, which emerges during anger or when he abandons the facade.

Within The Shuffle, he contributes to group performances including the song "Koi no Royal Straight Flush." His foremost talent is dancing, and he upholds the personal aspiration "To be ahead like a spade." Cherries stand as his preferred food.
