Boku to Senpai no Tekken Kousai

Himeko comes from a prominent Japanese business family known as the Koigakubo. She is often described as having "violence-seeking eyes" due to her pattern of forming deep attachments to violent individuals. Shuuji Aoyama, her assigned bodyguard, is hired by her family to protect her. The two refer to each other as "Senpai" and "Shu-chan," but their connection may be more complex than it appears.
