After a mysterious man in a black suit disappears from the scene of the car crash, Allen Rego is taken to the hospital only for the doctors to find that he isn't what they expected.
Allen, who now classifies himself as a "monster", is blackmailed into getting adopted by the Echizens' who were in America and nearby at the time of the accident. Ryoma isn't sure what to think of the ash-blonde haired boy who looks like a broken marionette. Deciding to get to know him, Ryoma sets his fate as he gets closer to Allen.
Once Allen makes it to school, questions appear in the air but aren't answered. Wanting it all to stop, Allen locks himself in his room. When the man in the black suit appears once more, Allen is more then just broken in the end.
