Senpai, Jitaku Keibiin no Koyou wa Ikaga desu ka?

One day, Hajime Tamachi, an apathetic man, receives an unexpected message from Renafalt, a friend he met five years ago in an online game, whose face he has never seen: "Senpai, how about hiring a home security guard?" Convinced that Renafalt is 200% a man, Tama arrives at the meeting spot and sees someone with a red suitcase, just as they had arranged. However, that person turns out to be a beautiful girl with large breasts. "Ah... A-Are you... Senpai?"
