Boku to Senpai no Tekken Kousai

Himeko Koigakubo is the heiress to one of Japan’s most powerful corporate dynasties, yet her privileged upbringing masks a deeply unsettling trait. Those around her whisper that she possesses "violence-seeking eyes," a reflection of her dangerous tendency to fall unconditionally in love with volatile and unhinged individuals. To manage this unpredictable behavior and ensure her safety, the family has contracted Shuuji Aoyama as her personal bodyguard. On the surface, their dynamic appears strictly professional, but the two share an unusually intimate rapport, affectionately addressing one another as "Senpai" and "Shu-chan." Beneath these familiar nicknames lies a hidden truth that neither reveals to the outside world. As they navigate the pressures of her family's legacy and her reckless romantic inclinations, the true nature of their bond begins to blur the lines between duty and devotion. Their secret suggests that the connection between the guarded heiress and her protector is far more complex than it initially seems.
