SpoilerRias begins to develop feelings for Issei in Volume 2. He remains ignorant to her advances though, viewing them as the adoration a master would show a pet. He continues to misunderstand Asia's feelings as well until Volume 6 when she kisses him. Akeno admits she has feelings for him in Volume 3 and begins actively pursuing him with flirtation and seduction. Koneko warms up to him after Volume 5 and begins to develop feelings for him as well. In Volume 10, he confesses to Rias that he loves her and she returns his love. They start dating afterwards.
In Volume 11, while battling Shalba Beelzebub in another dimension, Ise is wounded by a cursed arrow and collapses. An attempt to retrieve him returns nothing but the 8 Pawn pieces Rias used to resurrect him originally. Though his whereabouts remain unknown, he is presumed dead.
