Kazeno Sumire is a character from the anime Rokudo's Bad Girls, known for being one of the Sumire triplets. He is the middle child of the three siblings, with a twin brother named Raino Sumire and a sister named Amano Sumire.

Regarding his background and personality, Kazeno is a male character who frequently crossdresses as a female and adopts the mannerisms of an idol. His appearance is marked by blonde hair and red eyes. As an executive of the Onishima Alliance, a major student gang known for committing various crimes, he holds the rank of Number 5 alongside his brother Raino.

Kazeno's motivations are closely tied to his family. He is fiercely protective of his sister, Amano, and his actions are often driven by a desire to safeguard her. His role in the story becomes particularly prominent during the Onishima Alliance arc, where he provides assistance to his sister. He is initially disturbed by the protagonist Tōsuke Rokudō due to seeing the effect Rokudō has on his sister, which he perceives as her falling under Rokudō's power. While he, like his sister, idolizes a figure named Amano, Kazeno's personal goal is to stand as an equal to this person rather than simply follow in their footsteps.

Kazeno's key relationships are primarily with his siblings. As a member of the Sumire triplets, his dynamic with Raino and Amano defines much of his character and involvement in the plot. He engages directly with the story's conflicts during the Onishima arc, demonstrating his loyalty to his family and his capabilities as a fighter. A notable aspect of his ability set includes his skill at crossdressing, which is an integral part of his identity and idol-like persona.
