Actually the MC is reincarnated it is said in the chapter where he kisses Frayja she says he is experienced and the MC says he has not kissed a women in life at least this life. Also the MC has a divinity for Void and Infinity so according to me his personality is acceptable I will agree however that the novel is a confusing because of not showing any character development. and the beginning could be done a bit better

The power ranking given by Evil_for_the _Win in much better then u gave. u could use that(it is a comment on the author note)
