High School DxD, Vol. 14 (light novel) — Ichiei Ishibumi

Issei's many triumphs have finally won him the adulation he's always hoped for, although not with the crowd he would've liked. Rather than legions of adoring ladies, he's got tons of mages clamoring to make a pact with him! Well, so long as he finds a cute mage girl, it'll all be worth it, right? Meanwhile, Gasper receives an order from his vampire family to return home. Why would they want him back after neglecting him for so long?
