Φなる・あぷろーち

The Mizuhara siblings are the first to be chosen for the R.T.P. project. The brother and the sister, Ryo and Akane, have long been living together in the same apartment. Still in public school, the two have endured a difficult life after their parents' death some years back. Ryo, the main protagonist, has assured to himself that all is well; he and his sister are living on well-paid wages, and he only needs his sister. The vision of his future is soon to be shattered by the R.T.P. when his planned fiancée, Shizuka, enters his apartment one night with several government bodyguards. By some preliminary actions taken by the government (as precautions), Ryo is forced to house his new wife-to-be, despite his refusal.
