Senpai, Jitaku Keibiin no Koyou wa Ikaga desu ka?

One day, Hajime Tamachi, a typical bottom-feeding loser, receives a phone call

“Senpai, will you hire me as a housemaid?”

The person who called was "Rena", a friend he had known for 5 years through online games, but he doesn't know her real name or appearance.

"Actually, I'm a cute high school girl with big breasts!"

Hajime was tempted by those words and went to meet her, and what awaited him was the real thing just as she promised!
