Review Detail of B6_12nn3 in DXD : Rebirth As A Random Guy

This has to be the most dogshit plot in all of dxd fics ever. I am surprised how this mc was able to survive in real life up to the age of 25 with a peanut sized brain. This guy for no reason visits or and tells rias and gang about his transmigration in this world and that they were manga characters in his world. He claims it is for his survival. He could have lived peaceful life forever with his family acting ignorant about the supernatural but he has to go ahead and create a butterfly effect to mess up the plot which he has knowledge of . He claims he wants to save more life by telling the main cast about the future not even thinking that the butterfly effect can also cause the opposite.
