I read through all of the translated chapters, and it looks like we got another Erotic Manga headliner. The MC was originally part of a group of people summoned to another world. As each person was guided on their journey, it seems his special ability is s_xual. In a nutshell, he can summon an Angel and he simply needs too.. "do it" with her to become stronger. It's somewhat odd to see items dropped as they engage in the deed which he can use to level up. So you move up in this world by using your ability to engage in lovemaking while using up resources. It's so "intense," that theMC even loses HP, bruh.

On the bright side, the story is not lackluster in any way. It is surprisingly well-rounded with a lot to offer for the long term. What really pulled me in was his interactions with other players.
