Moukaku is introduced in Ikkitousen: Xtreme Xecutor as one of the leaders of Nanban High. Before the start of the series, She along with her sister Mouyuu, attempted to conquer the entire Kanto region. They were however stopped due to the emergence of the Nanyou, Seito and Kyosho heads. At the start of Xtreme Xecutor, she forms an alliance with Kentei. She is currently in battle against Chouhi Ekitoku. Moukaku, wears a very revealing outfit, consisting of yellow shorts, sleeveless yellow jacket exposing her bra, a yellow peak hat and yellow boots. Personality-wise, Moukaku is very condescending, adding "bakayarou" at the end of her sentences. She fights using a modified Chinese ring, which she uses for hand-to-hand combat as well as a throwing weapon. She along with Mouyu would experience a change of heart, and decided to re-evaluate how they viewed life and competition and would leave after Episode 11.
