From Nagareboshi Manga:
Aria’s parents have been gone since she was very young. Thus, she’s had to grow up in a “foster home” of sorts, and was raised by nuns. On her 16th birthday, Aria recieves a present in the mail– a ring from her “Daddy-long-legs” (a man who protects someone from afar while they’re growing up)! All of a sudden Aria’s life is thrown into chaos. Men try to run her over with cars, shoot her, and kidnap her. Relief comes in the form of Canon, who claims he’s her bodyguard. But can he keep Aria safe forever?

A story set in the near future, about a middle-aged loser whose only refuge is a virtual bishoujo game.
Takuro, the main character, is a stereotyped, low self esteem, adult male in a dead end job. Because he feels he has nothing to live for, he let himself go, becoming fat, miserable, and lonely. The only shining thing he lives for is the occasional visit to a brothel where his savings will allow him to at least not be completely sexless. This is when, through a real life friend of his, he is introduced to the virtual reality world of "The Unreal". Where, after spending $6000+ on equipment, you can purchase a virtual girlfriend who only thinks of you. Only the girl, Tsukiko, that Takuro purchases, seems to have come with a few defects.
