After inadvertently managing to kill the god Verethragna, taking his divine powers in the process, the once-typical teen Godou's life changed forever. Now a "Campione", a god slayer, the boy constantly attracts both gods' and other Campiones' attentions alike, not to mention the affections of a powerful knight, Erica. Whether he's dodging Erica's advances, proving his strength to others or taking down gods who will wreak havoc on the planet, Godou's new life is anything but normal.
Akuto Sai enters the Constant Academy for Magick Arts hoping to become a high priest and change the world for the better. But when the school's oracle declares his future profession to be 'Demon Lord', he finds himself feared and hated by the entire student population. Now, instead of making comrades and studying for his exam, Akuto finds himself fighting off monsters, bullies, and well-meaning classmates in various states of undress. If navigating a magical high school as a transfer student wasn't difficult enough, Akuto now has to deal with a cute android ordered to observe him 24-hours a day, the precocious attention of the flying, invisible and naked Keena Soga and the advances of the school's most popular girl. Will he be able to overcome his fate, pass his classes, and mend his friendship with the violent Junko Hattori, or will he succumb to his demonic destiny?
Both of these are fantasy shows with an interesting premise and powerful protagonists. Whether it's being the Demon Lord or the Campione, both leads manage to find themselves in interesting situations revolving around their bountiful female casts. If you like one, you're bound to like the other.
Both are about a guy who didnt nessecarily choose to be powerful but had this power thrust upon... neither of the main characters likes to be called by their respective title "Demon King" or "King/Campione". and also they're both harems... oh and they both fight magical beings... Id say if you like Ichiban Ushiro no Daimaou you'd like Campione! and if you liked Campione! you might like the other...
Both have a similar kind of storyline with a harem also both MC's wield great power, Ichiban Ushiro no Daimaou has more Ecchi/fanservice scenes but both of them or very good nonetheless.
In both series our teenage male lead becomes some sort of demon lord and quickly attracts female followers. The main concept is similar, but to be honest both series are just very cheesy harem ones. Still if you had fun watching one, you might try your luck with the other one.
You know what they say, wenches love power. Ichiban Ushiro no Daimaou is about a guy who is destined to be a Demon Lord, all powerful and stuff, while Campione! is about a guy who becomes a... well, Campione. God killer. But both obtain power when they don't particularly wish for it. With enough comedy and fanservice to complete the cake, both harems are good, dumb fun with some barely suggestive scenes.
All the perverted Issei wants is to squeeze bountiful boobs all day long, so he's thrilled to join Kuou Academy, a once all-female high school filled with gorgeous girls. But little did the boy know that after finally getting a girlfriend, she'd turn out to be a fallen angel who'd drive a lance through his heart, killing him on the spot! Luckily, the beautiful and busty Rias, his popular classmate who's actually a demon, revives him under one condition: that he'll become her servant. Now, Issei finds himself in the middle of a fierce chess game between demons, fallen angels and exorcists, and the fates of his new friends lie in the balance!
General story is similar, the main character gains supernatural powers and is dragged into a world of Gods/Devils leading to many fights and forming a harem along the way.
Well there are similar elements in both animes, such as fanservice/ecchi, fighting scenes, loads of humor and girls. It is likely that you would like both animes, when you like one and if you ask me, both animes are definetely worth watching.
Keep in mind though that the male main charakters differ a lot, since the one in High school DxD is quite the perv.
1 hero, 4 beautiful girls, 1 strange (ecchi) way to get stronger, 1 great power that mysteriously appear in the hero... same idea!!
Self-proclaimed, proud pervert Ryousuke loves women – to him, their butts and breasts are a 'treasure box' of joy for all men. So when the boy spots a fiery-haired girl standing in the rain one day, he invites her to his house – but he didn't expect to be stabbed with a magical sword in return! The girl, Lisara, is actually a high-level shinigami who must absorb the spiritual powers of others to survive in the human world. Until she can find a genius with enormous expendable energy, she's decided to form a contract with Ryousuke, but unfortunately for the busty babe, the horny teen's mojo is fueled only through his constant perversion. While looking for Lisara's true prize, the two must deal with other well-endowed shinigami and other foes alike, all while trying to maintain a 'typical' school life together.
In both have demons, have four beautiful girls, have the perv hero that coincidentally "earn" one of the best weapon ever, have the main bad guy, and have the ecchi way to make the hero stronger.
Both High School DxD NEW and Campione! are filled with ecchi, fantasy, and comedy. Each have a main character that are surrounded by a cast of mainly female characters. Both female leads are busty and a bit forward with the male lead. Chances are if you enjoyed the comedy and nudity filled scenes of one you'd like the other
