OVA
Description
Shiryu Chou'un serves as a Special A-Rank fighter at Seito Academy and one of the "Five Tiger Generals" under Gentoku Ryuubi. Her character inherits the soul of Zhao Yun (Chou'un), the Three Kingdoms-era general nicknamed "The Eternal Victorious" for losing only one battle and dying of old age at 72. This lineage shapes her formidable warrior role.

Physically, Chou'un possesses long silver hair reaching her back, with bangs covering her forehead and strands framing her face, often obscuring her ears. Her eyes remain typically closed, rarely seen by others. Standing 170 cm tall with measurements of 89-59-87, her standard attire includes a brown vest over a striped white collared shirt, a dark brown skirt with red stripes, knee-high black socks, and brown loafers. A tiger tattoo appears on her left shoulder blade in some depictions.

Chou'un's personality reflects loyalty and a calm, kind-hearted demeanor. She follows Koumei Shokatsuryou's orders without question and expresses unwavering devotion to Gentoku Ryuubi, stating she would die to protect her. Despite her combat prowess, she avoids unnecessary violence, believing conflicts can resolve without bloodshed. Her laid-back nature contrasts with moments of self-criticism, like disappointment after over-pruning a bonsai. Later appearances show blushing and implied romantic feelings toward Gentoku.

Her combat abilities are exceptional. She wields the Youtou Muramasa sword "Zanryuu" and employs techniques like "Shiden Issen." She effortlessly defeated Teni with a single strike and overwhelmed Shimei Ryomou while fatigued. During an assassination attempt on Gentoku, she protected her while fighting attackers with eyes closed. Regarded as one of the series' strongest fighters, she rivals Unchou Kan'u in skill. Brief glimpses of cat-like eyes and her suppression of Ryomou's dragon during the Dragon Jade incident hint at a potential dragon connection.

Chou'un's narrative spans multiple installments. In *Dragon Destiny*, she retrieves the Dragon Jade under Koumei's orders, defeats Teni and Ryomou, and delivers the artifact to Kan'u. She later intervenes when Hakufu Sonsaku's dragon runs amok but is stopped by Ukitsu. *Xtreme Xecutor* intensifies her protective instincts toward Gentoku, featuring subtle romantic undertones. The 2022 OVA *Shin Ikki Tousen* depicts her fighting through enemy territory to confront adversaries, reinforcing her combat role.

While her background in *Koihime Musou* diverges—portraying her as a flirtatious, menma-obsessed fighter with a "Kachou Kamen" alter ego—this remains distinct from her *Ikki Tousen* canon. The primary series emphasizes her loyalty, strategic combat, and subtle emotional depth, particularly in relationships with Gentoku and Seito's leadership.
