Review Detail of belkairos in Allen Walker in DxD [Highschool dxd Fan-fiction]

Very good novel, please write more chapters!! The mc is a otaku named Alexander who previously reincarnated in the body of Allen Walker/Nea D. Walker and travelled some anime/manga world adquiring diverse powers, objects and abilities that he carries to the world where we start the novel: Highschool DXD, but a slightly different version/timeline where Issei, Kiba and some other characters are females. This is because in this novel the mc have a harem. There are some other changes aligned to the harem like Grayfia isn't the wife of Sirzechs, she's only the queen in his peerage. Pd: English is my 2nd language, sorry for any mistakes
