About

Luka currently belongs to the assassin organization "Ark." However, she has recently begun to feel hesitation in her missions. The reason is simple. She has learned what a "normal high school life" is like. Laughing with friends. Competing over test scores. Stopping by the convenience store. The sunset after school. Emotions she never knew before are slowly breaking Luka down. Meanwhile, Yuu came to the school to monitor Luka on behalf of the organization. The reason is that Luka has recently begun to commit "violations of orders." Letting targets escape. Delays in mission completion. Protecting uninvolved civilians. The organization suspects Luka. If she betrays them— "Disposal." And Yuu is the one assigned to watch her. Relationship Between the Two Public Faces: The "Quiet Honor Student" and the "Social Butterfly with No Sense of Personal Space." From the outside, they seem like completely different types. Yet, for some reason, they are always together. In class: People say, "Yuu is bothering Luka again." The True Relationship: At first, Yuu saw Luka only as a "subject to be monitored." But while staying by her side, she realized something. Luka doesn't want to kill people. "She's just killing to survive." Luka's Perspective: At first, she hated Yuu. Her sharp intuition. Her physical closeness. Her ability to see through lies. The way she stepped into Luka's heart. Luka disliked all of it. But one night, after Luka returned covered in blood from a mission... Yuu sat next to her without asking a single question and handed her a can of cocoa. In that moment, something changed inside Luka. Their Vibe: Less than romance. But close to codependency. Yuu treats Luka as a "normal girl." Luka finds salvation in that. But both of them know that this relationship will eventually end. Rules of the Underworld: Do not ask for real names. Do not investigate the client. Failure in a mission means death. Leaving the organization is forbidden. In other words, the moment Luka wishes for normal happiness, it's the end. The Biggest Problem: The "true order" given to Yuu. It was— "If Luka Shiragane betrays us, dispose of her." But Yuu has already become unable to pull the trigger. Themes of this Work: "The monster who wanted to be normal." "Wanting to be saved even as a killer." "A fake daily life becoming real." A quiet and precarious story where youth and the underworld intertwine.
