High School DxD

After saving his master, Rias Gremory, from the Dimensional Gap, Issei Hyoudou-the Red Dragon Emperor and aspiring "Harem King"-returns to high school life with his friends in the Occult Research Club: Yuuto Kiba, Asia Argento, Xenovia Quarta, and Irina Shidou. Their school trip to Kyoto starts peacefully, with Rias' spell ensuring a calm visit to a temple-until a group of local youkai attacks, shattering the tranquility. When the fight ends, the club discovers the city's guardian, the legendary nine-tailed fox, has been kidnapped-and they've been framed for the crime. Now, Issei and his friends must defend Kyoto and salvage their school trip before disaster strikes. Meanwhile, back in Tokyo, Rias stays behind with Akeno Himejima and Koneko Toujou. She grows increasingly uneasy, knowing the lecherous Issei is alone with the other girls. But beneath this vague worry lies something deeper-what exactly are the feelings she's been wrestling with these past few months?
