a childhood friend's return. (high school dxd harem x OP male oc)

Toad Belfegor is the childhood friend of Rias Gremory and Sona Sitri and the heir of one of the 72 pillars of the underworld. Apparently both girls always had a huge crush on him. He had to leave the underworld for 5 years for some training and increasing his peerage. After those 5 years, he returned to his childhood friends to not only help Rias get out of her engagement but to also be engaged to her and Sona as well, along with any other girl who may fall in love with him.
