Running into your new stepsister in the bathroom is not the best way to make a good first impression, which Basara Toujou learns the hard way. When his father suddenly brings home two beautiful girls and introduces them as his new siblings, he has no choice but to accept into his family the Naruse sisters: busty redhead Mio and petite silver-haired Maria.
But when these seemingly normal girls reveal themselves as demons—Mio the former Demon Lord's only daughter and Maria her trusted succubus servant—Basara is forced to reveal himself as a former member of a clan of "Heroes," sworn enemies of the demons. However, having begun to care for his new sisters, Basara instead decides to protect them with his powers and forms a master-servant contract with Mio to keep watch over her.
With the Heroes observing his every move and the constant threat of hostile demons, Basara has to do the impossible to protect his new family members. Moreover, the protector himself is hiding his own dark secret that still haunts him to this day...

One morning, he accidentally stumbles upon Stella Vermillion, a visiting princess and A-ranked Blazer who has just enrolled at Hagun, in a state of undress. As a result, she challenges him to a duel where the loser will be the winner’s slave. It seems like a surefire win for Stella, but could there be more to Ikki than meets the eye?

“Awaken now, Kasuga Arata.” With those words, Arata’s uneventful, carefree life ends forever. A black shadow covers the sun and Arata’s entire town is reduced to rubble, all the people in it spirited away by the blackness of the sun in an event called a "breakdown phenomenon". As Arata’s memories come flooding back, he realizes he’s been living inside an illusion created by a powerful book of spells.
Lilith Asami, a mage dispatched to investigate the phenomenon, gives Arata two choices: hand over the book, or die. Arata chooses the third option: enrolling in the top-secret magic school Royal Biblia Academy. Waiting for him at the academy are seven beautiful magic users, the Trinity Seven, each with her own power and skill. With so many women surrounding him, there are plenty of opportunities to have some silly perverted fun.
But it’s not all fun and games for Arata. Spurred on by the memory of his cousin and childhood friend Hijiri Kasuga, Arata will stop at nothing to stop the destruction of the world and bring his best friend back.

6. Dakara Boku wa, H ga Dekinai.
NEVER make a deal with a wet goddess you've only just met. That's a lesson Ryosuke Kaga learns the hard way when he foolishly agrees to let Lisara Restole use some of his "essence" to stay in this world. Because despite her smoking hot appearance, Lisara's actually a Shinigami, a Goddess of Death. However, she DOESN'T steal years off his life like any decent Shinigami would do. Oh no, instead she sucks him dry of something much more perverse by leeching off his lecherous spirit and draining his ability to enjoy... er... the things that teenage boys normally spend most of their time thinking about! And now that he's been de-debased and de-debauched by her un-dirty trick, the poor regenerated degenerate's only hope of getting his licentiousness renewed is to join the queen of mental-clean on her quest, since when she leaves our mortal plane he regains his normal immorality! But the termination of the probation of his reprobation isn't guaranteed, because Goddesses of Death can be really harsh mistresses and it's going to be anything but easy to go back to being sleazy!

About thirty years prior to the start of Hagure Yuusha no Aesthetica, a number of selected people from Earth were summoned to other worlds with only about half of them being able to return. One of the young people chosen was Akatsuki Ousawa, who was sent to Alayzard to defeat the Dark Lord Garius, which he did, before returning to his original world. Some of the successful chosen ones brought back little trinkets as souvenirs. Akatsuki, on the other hand, went a different route—he brought back the defeated Dark Lord's daughter, Miu, who is now posing as his long lost little sister!
Upon returning, Akatsuki and Miu are forced to join a special school called BABEL where they must train to one day master the powers they gained in Alayzard, in hopes that they will one day be able to serve mankind. Will Akatsuki and Miu be able to keep her true identity a secret or will their plan to live peaceful lives together go up in flames?
