Intro. In this world you are the strongest, you are Irina's childhood friend and all the girls love you and hate Issei (as it should have been in the anime but no way XD). You are immune to Rias' servant spell and Koneko considers you to be her owner and loves you more than anyone else, just like the other girls.

High School DxD. - The strongest
