Ren Takahashi, a shy, hoodie-wearing tech genius, hides behind the online alias GhostHood — a quiet legend in underground hackathons. Despite appearing average in school, he dreams of becoming a real-life Iron Man — not the hero, but the builder of world-changing tech.Enter Aoi Hoshizaki, a bold, gal-style girl with a love for code, a messy room, and a mysterious spark. When she moves in next door and discovers Ren's secret, their world begins to change — from quiet club meetings to national hackathons, late-night debugging sessions to secret rooftop conversations.What starts as teamwork grows into something deeper, more complicated, and far more electric than either expected. Together, they aim for Japan’s most elite tech university — and face rivalries, rumors, and the whisper of love in every line of code.
