Summer's here, and before anyone knows it, the rating game between the Gremory and Sitri houses is scheduled to take place in the devil realm! Issei and the gang jump right into some hellish training, but something's not right with Koneko-chan...?
THE KNIGHT SEEKS REVENGE With a sports festival on the horizon, the Occult Research Club expects smooth sailing after all the recent trouble. Everyone seems happy enough—except for Kiba, that is. The pretty boy hasn’t been himself since he saw an old picture of Issei. Things only get worse when two beauties arrive in town with powerful Holy Swords called Excaliburs—deadly weapons Kiba long ago swore to destroy. Issei promises to help his friend, but do the demons really stand a chance against such legendary might?
A VACATION IN THE UNDERWORLD! School's out for the summer, and Issei's already dreaming up fantasies of hitting on hotties at the beach. His master, Rias Gremory, has other plans for him and the rest of the Occult Research Club, however—a season-long training stint in Hell. As if that wasn't disappointing enough, Issei's instructor is a terrifying dragon that tried to kill him! It may sound like a brutal lesson plan, but he'll need it because a few of Vali's allies decide to crash an underworld party and stir up trouble. What's more, one of them bears a striking resemblance to Koneko...
ASIA’S GETTING MARRIED?! Long ago, Asia used her Sacred Gear to save the life of a demon, a benevolent act that resulted in her being ousted from the Church. Now that demon, Diodora Astaroth, is back and hoping to wed Asia. She refuses, but the seemingly friendly man is persistent. As the Gremory Familia’s next Rating Game opponent, he wagers that if he wins, Asia will be his bride. Naturally, Issei’s not about to let some pretty boy snatch up the blond beauty in his life, but Diodora’s machinations may prove more sinister and cunning than initially suspected. Returning home with Asia could require drastic measures...
IT AIN’T EASY BEING A DEMON! Life as a demon in a Familia filled with beautiful girls sounds like a dream for perverted teenager Issei Hyoudou, but it’s more often bouncing from one disaster to the next! Whether helping a young woman in love who constantly wears samurai armor, hunting for a familiar in a perilous forest, or dealing with three hundred clones of himself, Issei’s always got his hands full (and not in the way he’d prefer)! This collection of short stories sheds light on the lecherous young man’s chaotic days and expands the DxD world!
A SHUT-IN TIME STOPPER! After the recent trouble with fallen angels and Excaliburs, Rias is finally allowed to unseal her first Bishop—Gasper. Issei is thrilled to find that this new addition appears to be a cute blond girl...but his hopes are quickly dashed. Not only is Gasper a cross-dressing boy, he’s also a total recluse with the power to freeze time! As if getting a shut-in to come out of his shell wasn’t hassle enough for poor, perverted Issei, a peace conference among demons, angels, and fallen angels being held at his school is beset by terrorists! Could this mean the beginning of all-out war?
After a perilous start to the semester, peace is finally returning to Kuou Academy. At least, until Odin, a god from the Norse pantheon, shows up. Dealing with the lecherous old man is tough enough on its own, but a sinister group is also plotting to kill him. Issei and his friends will have to pull out every trick they can manage to make it out of this one!
The fateful rating game has finally begun! Rias and her team may be hot stuff, but they find themselves struggling against Team Sohna and its members, who are putting their very lives on the line! When things look desperate, Issei's strongest-ever technique explodes forth! And it's coming for Team Sohna's...boobs?!
Is love in the air between lowly servant Issei and his mistress, the bewitching Rias?! Reincarnated as a demon by Rias, the school beauty, Issei finds himself in servitude to his devilish mistress. But when Issei befriends Sister Asia, a nun from the Church, which is widely known to be hostile to demonkind, he's practically asking for a target on his back-as Rias is quick to inform him! Worse yet, when the good sister is kidnapped by a fallen angel, Issei rushes to her aid! But little does he know that Heaven plays dirty...!
A KIDNAPPING IN THE OLD CAPITAL! Issei and the other second-year students at Kuou Academy are off to visit Kyoto for their school trip. Everyone’s excited for a few days of sightseeing and souvenir hunting. However, the fun comes to an end when the Hero Faction of the Khaos Brigade abducts a local fox spirit princess! Issei’s not about to let some villains get away with taking an innocent woman (especially not one with an ample chest!), but his opponents are descendants of mythological champions. Worse, they’ve all got Balance Breakers! Does the Red Dragon Emperor stand a chance without his beloved Rias by his side?
