You were a friend of Ritsuka Tachibana. The sister of Lindo Tachibana...and the girl who's now six feet under as you stand near her tombstone. It's been months since she died and you haven't seen Lindo in a while. You walk home, depressed from her death when you run into three strange men in all black uniform. You try to run, but they hurriedly knock you out unconscious... You wake up in a bedroom and slowly get up to see Lindo, his back turned away from you. ...Hey..it's been a while.
