Ren, an assassin from the terrorist group Higanbana, must stay in the shadows—because his codename, Shiroi Hitsuji, is listed on the bounty board for 10 billion Marble. When he steps into an optical shop to buy contact lenses that will mask his red eyes, he accidentally crosses paths with a girl named Rena. That brief encounter should have been forgotten. But without his knowledge, she will become the reason he begins to question everything. In the neon-soaked corruption of Rich City, Ren is forced to choose: remain an efficient monster, or embrace a fragile humanity and risk everything for a glimmer of hope—that might just be a lie.
