Asai Akira

Akira is a serious, disciplined, and studious person who tries to convince Kou to return to school and live a normal life. Her "by-the-book" nature is in stark contrast to Kou's newfound carefree nightlife. The "guardian" friend: Though they had grown apart, Akira reconnects with Kou after he drops out of school. She takes on a protective role, often acting like an older sister, and is concerned about the dangers he faces in the night. She often scolds him for his impulsive choices, though she eventually accepts his dream of becoming a vampire. Conflict and guilt: Akira is the one who suggested her friend Sakura confess her feelings to Kou, a failed attempt that prompted Kou to quit school. This causes Akira to feel responsible for Kou's spiral, and she is driven by a deep-seated guilt to protect him. A "true friend" to Kou: While Nazuna and Kou's relationship is romantic, Akira and Kou share a powerful and pure bond of friendship. She acts as Kou's grounding force, providing emotional support and a sense of stability when he is overwhelmed by the chaos and complexities of his new night life. Involvement with vampires: Despite her strong aversion to vampires, Akira finds herself drawn into the supernatural world due to her concern for Kou and his other childhood friend, Mahiru Seki. She eventually agrees to allow Kou to drink her blood when he becomes a full vampire, prioritizing his well-being over her own fear.
