Koumei Shokatsuryou, successor to Zhuge Liang and known as the "Crouching Dragon," attends Seito Gakuen as a C-Rank Toushi. She possesses light green hair tied in pigtails adorned with red beads, blue eyes, stands 143 cm tall, and has measurements of 60-48-58. Raised by tiger generals at Tougenen temple, she typically wears its monk attire and developed fishing skills. Her personality is consistently emotionless, rarely smiling or showing anger. Despite this reserve, she demonstrates deep care and loyalty, particularly towards Seito's leader, Gentoku Ryuubi. Koumei exhibits possessiveness over Gentoku, openly claiming Gentoku belongs to her and expressing fascination with Gentoku's breasts. She considers Gentoku her "weakness," implying profound affection. Her hobbies include fishing and sleeping, and she displays maturity and strategic influence beyond her apparent age. Harboring the spirit of master strategist Zhuge Liang and later awakening his dragon spirit, Koumei acts as a brilliant strategist manipulating events behind the scenes. She shows unconditional loyalty to Gentoku, making crucial independent decisions for Seito's goals. Her strategic prowess includes orchestrating conflicts between rival schools Kyosho and Nanyo to buy time, accurately predicting enemy movements like Kyosho's festival attack, and planning alliances such as surrendering the Dragon Jade to Nanyo for cooperation. Key narrative involvements see her receiving early reports on strategies against Moutoku Sousou's forces. She participates in the Battle of Red Cliffs, confronting rival Chuutatsu Shibai and mocking Kyosho fighters to provoke action. During this battle, she stays near Gentoku and the Dragon Jade, facing threats like Bunken Gakushin before witnessing Gentoku's rescue by Hakufu Sonsaku. Koumei orchestrates the Dragon Jade's release to stop Sousou, enabling his defeat. Post-battle, she returns to her favorite pastime, fishing, demonstrating exceptional skill by catching large quantities of fish. She wields a hand fan and her strategic mind directly influences the recreation of the Battle of Red Cliffs to prevent Seito's destruction, advising Gentoku that peace may require difficult, violent actions. Her relationships extend beyond Gentoku to include loyal servants like Youjou Bashoku and Shiryuu Chou-un, whose allegiances she secured at Tougenen.
