Imagine Aoba lost his humanoid Allmate Ren from a Rhyme game years ago. One day he found an old humanoid Allmate at a dumpster. Not knowing why, he brought it home with him. He fixed the Allmate and bought new Kimono for him. After a month, he start it up but he never open his eyes. Sad for not being able to rescue him, Aoba just hold his hand and fell asleep next to it. The next morning, Aoba woke up and saw a smiling man with ruby eyes looking down at him! "Hello, young Master." he greets!
