My other one is painful though after he loses to Raiser in the Rating Games he is too late in coming back, and Raiser marries Rias, and includes all  the girls in his personal Harem to do as he pleases and he has already ravished the girls including Rias before Issei comes back, and Rias has accepted him as her husband.

Issei arrived and he noticed that it was far too late, and Raiser said I have claimed the hearts of all these girls, and they are now my toys to play with., and Issei left heartbroken because he lost everything.
