Akatsuki Ousawa returns from another world after defeating its Demon King, with a busty, pink-haired girl in his duffel bag. It turns out that this girl, Myuu, is the daughter of the very same Demon King he had defeated. Stranger still, the Demon King asked Akatsuki to take care of his daughter with his last breath. Akatsuki passes Myuu off as his sister while they are forced to attend Babel, an institution made to keep tabs and train other returning "heroes." It seems however, that Babel is privy to some shadowy prophecy, and that Akatsuki might play a big part in it.An animated adaptation aired in the third quarter of 2012, and will be released by Funimation in December 2013 under Aesthetica of a Rogue Hero. There is also a manga adaptation entitled Hagure Yuusha no Kichiku Bigaku, or literally A Maverick Hero's Brutish Esthetics.
Another Dimension - One which powers up visiting highschool students, surprisingly allows a trip home, and lets said students keep their abilities as souvenirs.
Alien Sky - The world Akatsuki visited, became a hero in, and took Miu from has two moons that glow blue and green in the sky.
Badass Princess - Myuu. She's able to fake casting one spell and punishing whoever takes the bait with a quick shot, which she demonstrates in a practice bout against a teacher of Babel, knocking him out in one action. She's also able to use her staff to block a monster who's several times her size and weight.
Blatant Lies - Myuu asks Akatsuki why she had to be naked as he took her across the worlds, and he replied that interdimensional travel is easier naked. Subverted in the original novels. It really was easier. note He basically cheated by using his Supernatural Martial Arts to place his energy in her body, fooling the gate into thinking she was part of him.
Blood Knight - Akatsuki's reaction to Kaito's unusual handshake is to ask if Kaito wants this handshake to escalate. Kaito backs off, saying he's only here to greet him. During their scuffle, both of them are clearly enjoying testing each other's skills.
Cleavage Window - Myuu's P.E. uniform inadvertently sports one - due to her "size" it can't be zipped up properly.
Cool Bike - Sleipnir, the supersonic bike, is introduced in episode 6. It's also an Empathic Weapon, shocking Akatsuki when he first tries to ride it, and later, frying Haruka's clothes off after she tries to confiscate the bike from its new master, Akatsuki.
Cool Sword - The sinister-looking sword that buries itself in the ground pointy end first after falling from the sky during the anime opening sequence is Akatsuki's. Uesaki Ryouhei has a pimped-out scimitar.
Cursed with Awesome - Akatsuki repeatedly states that he cannot use spells, and in episode 3 of the anime it is shown that he can't make use of Babel's Arms Device, a bracelet which supposedly creates a weapon fitting the wearer's personality, magic, and fighting style. Later in the episode, he is finally able to summon his weapon, but it takes at least seven of the bracelets to create a physical form for his powers.
Blow You Away - Nanase Haruka at the very least manipulates wind for flight. Also in the manga, Myuu's Sorting Hat-like test results reveal an affinity for wind, but the anime shows her casting spells of various elements.
Dishing Out Dirt - Doumoto Kuzuha, as well as the Student Council's Aihara Minami. Both can manipulate earth directly for attacks, or make constructs out of them.
Making a Splash - Izumi Chikage prefers to cover her target's head with a sphere of water. She can also blast enemies with water from her fingertips if there's enough of it nearby.
Gag Boobs - Miu. Her school uniform's top pops a button under the stress of keeping her endowments in check.And they are still growing! She even needs to buy new underwear because they are all too small now.
Genius Bruiser - Noted by a guy Akatsuki was fighting - "I thought you were just all brawn and no brains... but your cognitive ability is impressive."
Hubris - Despite being unable to defend herself from being stripped of her underwear multiple times by Akatsuki, Haruka still thinks he's nothing.
The Hunter Becomes The Hunted - A game on the beach where all the other contestants must bring back Akatsuki's swimsuit within an hour turns into this.
The Immodest Orgasm - Akatsuki bites the earlobe of a battle maid he's succesfully grappled. She gives a shriek, and crumples to the ground, dazed. In the manga, it is deliberately stated that his special ability can be used this way. In the anime, he can also make them lose control of their bladder too.
Instant Runes - When these start to come out of Akatsuki's right or left hand, you'll want to pay attention.
Intercontinuity Crossover - The first half of a three-minute promotional video for the Hagure Yuusha anime showcased Akatsuki fighting and winning against several Queen's Blade Rebellion characters. Perhaps due to the limited length of the clip, only two characters, Anelotte and Liliana, receive the usual Clothing Damage prevalent in Queen's Blade. The crossover happens courtesy of Hobby Japan.
In episode 5, Myuu switches the TV on to cover for a moment of awkwardness, saying there's a show she wanted to catch. The TV flips on to a battle scene from said promo video, Branwen and Liliana getting some extra screen time. While Myuu's gasping in shock, trying to process what she's watching, Akatsuki remarks that developing an interest in sex is completely normal.
Last Request: The Demon King asked Akatsuki to take care of his daughter with his last breaths.
Lovable Sex Maniac - Izumi interprets Miyu's attempts at stealth (pulling the two of them into a side alley) as an invitation to fool around in public.
Mugging the Monster - An unlucky Jerk Jock tries to put Akatsuki in his place. Seconds latter he's tossed at high speed into the hall, taking the classroom door with him.
Magic Knight - Ironically, Akatsuki fits the bill, despite having no magic skill at all. His control over chi can be used to augment his defense, allow an injured person to heal faster, or to throw an energy ball that ignores magical barriers.
Modesty Bedsheet - Myuu hastily wraps Akatsuki's bedsheet around her as a makeshift dress so she doesn't have to converse with him stark naked.
Potty Failure: Akatsuki can invoke this trope by using his powers to make girls lose control of their bladders.
Power Perversion Potential - Akatsuki's ability to control internal organs would usually be used to negate fatigue, or possibly as a One-Hit Kill by stopping a person's heart, but he uses it to make girls lose their bladder control or give them orgasms.
Akatsuki is also adept at focusing his chakra or chi, like onto his soles to let him stick to walls. He explains and demonstrates this by clinging to the shower walls with his bare feet - while Myuu was still showering.
The President's Daughter - Myuu is wanted by an Emperor of Al-Lezard dead because news of her continued existence might stir the remaining demons to unite once more and destroy civilization as they know it.
Projectile Spell - Glowing, tracking arrow variation. One to two hundred of these are not a threat for our hero, though.
Random Power Ranking - Supposedly, students work their way from E-class to A. Akatsuki and Miu enroll as part of Class 1-B. The Jerk Jock that Akatsuki humiliates on his first day of school is supposedly of Class A.
Tsundere - Princess Listy El Da Sherfied, and to a lesser extent Myuu. The way Myuu tries to invite Akatsuki to party up with herself, Izumi, and Kuzuha exemplifies it. As of the end of episode 6, Student Council Vice-President Nanase Haruka might be turning into one.
Vapor Wear - When Babel's female students are in P.E. uniform, they're not wearing bras.
