Revenant in an Anime World

Having the duty to reincarnate the souls from an extensive variety of worlds, 'God' ended up reincarnating a soul in a world where he shouldn't exist. A world where three 'anime' worlds are mixed in one. 'God', instead of crying on spilled milk, he decides to observe the newborn in this foreing world. **** (I do not own the front page) -It's a slow story. -'God' is not the MC, just an observer. -The MC soul comes from the 'Code Vein' world. -MC will have few memories about his past life, so when he reincarnates is a baby in all aspects. -The story has sexual content. (no NTR, no Netori, no Rape.) (It has 'incest' but they are not related by blood.) -The animes (I don't own them) for this story are: 1.-Grisaia no Kajitsu. 2.-Shinmai Maou no Testament. 3.-Highschool DxD. -The characters and their 'story origins' will be the same, however, I will not follow the story lines from the animes. **** Hi, this is my first project so I'm a newbie. And, even if this story is sort of a fanfic, I will give my all in this story. If you have an advice or constructive critic for the development of the project I will gladly read them and consider. For those who only want to write malicious critics, you are losing your time. I don't have many experience writting sexual content but in time I expect to improve. English is my Second Language so you may find some errors. I will appreciate if you give me advice in this.
