@Koni We had Desu Vault, Wicked House, then the Anoun, and now we have SSSSS trolling as always. The manga is pretty good, it is just not that popular because it really feels like a late 90s of early 2000s series. A lot of the people who are looking for it and enjoying it are feeling that nostalgia factor that a series like this brings. This kind of wack adventure, with the happy-go-lucky protagonist that will become a badass in the future, was the most used trope back in the day before the Isekai genre flood the market.
I love this kind of series.
