Multiverse sign-in system

A young man named Nick died and got a powerful system

This is a story about Nick who got a chance to travel to many worlds and see many different beautiful women , cough*cough*.... I meant different cultures and scenarios

- First world - Boku no hero academia
- Mc is in the cover pic

P.S( 1.This is a harem novel with many girls

2. The mc will be OP bt at the same time his powers will be slowly trained and deveolped to become op

This is my first story, and I am writing this to practice for my original story( and I won't leave this story unfinished once I start to write my original one ) , so if there is any mistake, I will be correcting it once the story progress.

** The characters of the anime and movies except the O.C in this story belong to their creators and authors and has nothing to do with me. Only the OC belong to me
