Description
Chōun Shiryū, alias Sei, hails from the Shin Koihime Musō series. Initially serving under Kousonsan, she debuts battling the Yellow Turbans alone against an army despite protests. Her formidable combat prowess catches Kazuto’s eye for her alliance potential. Corpse accumulation impedes her movement, prompting a rescue orchestrated by Koumei and executed by Kan'u. She later meets Kazuto, expresses instant affection, but delays joining his group to journey across continents. She ultimately joins alongside Kouchū after the Enshou battle, honoring her pledge to Kazuto.
Her personality blends serenity with playful flirtation. She seldom angers but exhibits perilous intensity when her menma or alcohol are disturbed—manifesting as cold, terrifying calm distinct from Kouchū’s reactions. Within Kazuto’s group, she’s deemed eccentric, inciting chaos for amusement or emphasis. Her unconventional tastes cement her as "the weird one." She obsessively consumes menma straight from jars or with chocolate fondue, sparking frequent disputes.
She secretly operates as the masked vigilante "Kachou Kamen" (Butterfly Mask), patrolling cities with dramatic speeches and tokusatsu-inspired poses. Despite only masking her face and retaining her standard attire, weapon, and fighting style, only Kazuto and Koumei consistently identify her—a fact she overlooks. Her delusions include elaborate Kachou Kamen origins, like resurrection by an Ultraman-like entity. This alter ego rescues Ryūbi from bandits, prompting Ryūbi’s infatuation; Chōun later teases Ryūbi about her savior, relishing the praise. OVAs depict absurd Kachou Kamen traits like mask-induced gigantification and Ultraman-style blinking nipple lights.
She positions herself as a "master of love" with Kouchū, advising Kazuto on romance. Despite her seductive exterior, she initially misunderstands sex—believing "pillow games" involve literal pillow fights. Early knowledge from observing soldiers enables competent handjobs but leaves her unprepared for intercourse during her first night with Kazuto. She rapidly learns, becoming one of the group’s most sexually informed members, openly accepting threesomes and Kazuto’s harem. She later conceives Kazuto’s child in Shin Koihime † Eiyuutan.
Her spearmanship excels in rapid stabbing techniques, blending speed and agility into a dance-like style—evidenced solo against 25,000 Yellow Turbans. Additional skills encompass hand-to-hand combat, mask-throwing marksmanship, horsemanship, and acrobatics (like balancing on Kan'u’s guandao tip). She possesses heightened strength, reflexes, speed, and stamina. Beyond physical prowess, she demonstrates sharp intellect, commando-like troop leadership, and strategic acumen, though she unofficially handles military intelligence.
Weaknesses include lesser raw strength versus peers, ego-driven monologues, menma-triggered conflicts, and communication hurdles from her eccentricity. Across media, core traits like menma fixation and Kachou Kamen activities remain consistent. Anime adaptations amplify her quirks for comedy, heightening randomness and inappropriate remarks. She transitions from Kousonsan’s service to the Shoku faction after Kousonsan’s defeat during the anti-Toutaku campaign.
