Tsubaki Kazama, successor to the prestigious nomadic Kazama clan, carries her lineage's centuries-long legacy without a homeland. She possesses dark blue hair and petrol-colored eyes, merging technological adeptness with exceptional ninja skills. Her superior aerial maneuverability is demonstrated through precise piloting of a propeller-equipped dragon, enabling controlled landings. This expertise in both tradition and innovation establishes her as a formidable presence.

Her arrival triggers direct rivalry with protagonist Himawari, centered on mutual interest in Hayato Madenokoji. Tsubaki asserts equal right to address him as "Master," mirroring Himawari’s relationship. Their conflict escalates into a structured Valentine’s Day competition where victory hinges on Hayato preferring one handmade chocolate over the other. Tsubaki relies on innate inventiveness and talent during this contest, contrasting Himawari’s tireless effort. Factions form around both competitors, occasionally attempting sabotage.

Beyond personal stakes, Tsubaki’s core objective involves leveraging Hayato’s potential assistance to rebuild her clan and secure a permanent settlement, ending their ancient nomadic existence.
