√Harem!

Nagata Ryuusuke was one of many normal high schoolers with no special talents and average appearance. Until one fateful day when an alien crushed him alongside his house by accident, killing him in the process. This alien did everything to help him. She fixed his house and even restored his body. However, the alien did not have data on “normal high schooler” so she had to recreate him as a “lucky pervert”, meaning he will get involved in a lot of H situations by accident.
