Fortunately, a high-level devil named Rias Gremory reincarnates the unmotivated adolescent and turns him into a servant. It marks the start of a critical period in Ichiei’s life as he learns the skill of survival in the cruel world of angels and devils. Since its debut, the series has amassed a big fan base, so it’s natural for fans to seek out more shows like it. If you’re seeking for some suggestions, you’ve come to the correct place. Several of these anime, such as ‘Highschool DxD,’ are available on Netflix, Crunchyroll, and Hulu.

12. Actually, I am… (2015)

Asahi Kuromine has always had affections for Youko Shiragami but has never had the bravery to confess his feelings. When her father discovers that she is a vampire, he decides to remove her from school because it could lead to catastrophic results later on. Asahi promises Youko’s father that he will keep her secret and protect her at all costs, realising that he will never see his crush.

Unfortunately, he can barely keep any secrets to himself, and keeping Youko’s identity becomes extremely difficult when additional supernatural animals enrol at the school. ‘Actually, I am…’ or ‘Jitsu wa Watashi wa’ is an underappreciated supernatural anime that usually revolves around legendary creatures – something fans of ‘High School DxD’ will undoubtedly appreciate and enjoy. Crunchyroll has all of the anime episodes available.

11. Highschool of the Dead (2010)

Takashi Kimuro makes the life-changing decision to kill his friend after he has succumbed to the undead when an unprepared world is overtaken by a terrifying disease that turns humans into zombies. However, when he continues his hunt for human life, he is met with a terrifying quiet and is confronted with a fallen society.

Fortunately, he eventually reunites with Rei Miyamoto, his friend’s lover, and other surviving classmates, who pledge to fight back and begin searching for their loved ones. ‘Highschool of the Dead,’ like ‘High School DxD,’ is an action-packed supernatural anime with ecchi and harem aspects that features a lot of daring semi-nude/nude moments that fans will undoubtedly like. The show is available on Hulu.

10. Otome Youkai Zakuro (2010)

Kei Agemaki, although being a second Lieutenant and the son of a powerful military general, has never been able to overcome his phobia of paranormal beings. Unfortunately, when he is sent to the Ministry of Spirit Affairs, Kei is left with little choice but to investigate paranormal cases that force him to confront his worst fear.

While there are few similarities between ‘Otome Youkai Zakuro’ and ‘High School Dxd,’ we highly recommend adding it to your watchlist because it is a criminally overlooked supernatural show that fans of the latter will undoubtedly enjoy. The anime may be viewed on VRV.

9. Bakemonogatari (2009 – 2018)

‘Bakemonogatari’ follows Koyomi Araragi, a young adult who narrowly escapes a vampire attack thanks to the heroic actions of Meme Oshino, a mysterious man who dwells in an abandoned building. While she generally escapes unscathed and reverts to human form, Koyomi retains some magical abilities as a result of the encounter.

She, on the other hand, does not allow the tragedy affect her and uses it as an opportunity to work with Oshino to save more lives by curing supernatural ailments – a route that leads to countless encounters with demons and other mythical creatures. While ‘Bakemonogatari’ lacks the ecchi and harem components of ‘High School DxD,’ the supernatural anime has a highly intriguing premise and multiple overlapping themes that keep it interesting to watch. Funimation has the series available.

8. Dakara Boku wa, H ga Dekinai. (2012)

Most of the time, Ryousuke Kaga is engrossed in his perverse sensual fantasies and makes his classmates uncomfortable, forcing them to expel him. While his lusty perversion may not appear to be of much help when he meets a Lisara Restall, a Soul Reaper, the two strangers strike a contract in which Ryousuke agrees to let her exploit his sexual cravings as a source of energy.

Lisara has arrived in the human realm to find a magically powerful individual, and now, accompanied by Ryousuke, she sets out to complete her task, only to unwittingly discover the dark truths of the human world. ‘Dakara Boku wa, H ga Dekinai.’ has a lot to offer fans of ‘High School DxD,’ from sexually suggestive sequences to supernatural undertones.

7. Omamori Himari (2010)

Yuuto Amakawa is an orphan who lives a tranquil and monotonous life until he is ambushed by a supernatural creature for the misdeeds of his ancestor. Fortunately, a mysterious cat-woman named Himari arrives just in time to defend him. The protagonist is astonished and perplexed to hear that he is the scion of a powerful family of demon-slayers, and that the charms that have protected him his entire life are no longer effective.

Yuuto, who has spent an uneventful life, is abruptly thrust into a world teeming with supernatural forces, as well as the unwanted attention of a slew of women. Fans of ‘High School DxD’ will recognise the similarities in the idea of both series and should add ‘Omamori Himari’ to their watchlist. On Funimation, you may see all of the episodes.

6. The Familiar of Zero (2006 – 2012)

Louise Françoise Le Blanc de La Vallière, a narcissistic mage who attends Tristain Academy, a well-known school for magicians, is frequently taunted by her classmates for her incapacity to cast spells. She accidentally summons Saito Hiraga while attending a summoning lesson, proving that she is not as horrible a magician as others claim.

While she treats Hiraga as if he is a slave, Louise swears to prove to her classmates that she is a far superior wizard to any of them. Meanwhile, Saito struggles to adjust to his new existence. Hiraga, like Issei, finds himself in the service of another person via no fault of his own, whereas the female protagonists in both programmes have magical powers and use them to keep the main characters submissive.

5. Shinmai Maou no Testament (2015)

When his father remarries and brings home two step-sisters, Basara Toujou, a former member of a Heroes clan, could never have thought that one of them would turn out to be the demon lord’s daughter and the other a servant. Basara’s former clan’s values dictate that he fight the two, but having adopted them into his family, he chooses to defend them instead.

While putting his life in danger for them, the protagonist conceals his own terrible, dark truths. Basara, like Issei, finds himself emotionally and sexually connected with demons who are supposed to be his sworn adversaries. ‘Shinmai Maou no Testament,’ like ‘High School DxD,’ features a lot of sexual 18+ content, as well as a lot of other related topics. Funimation has all of the episodes available for viewing.

4. Rosario + Vampire (2008)

Tsukune Aono’s parents send him to Youkai Academy, a boarding school for monsters where they learn to coexist with humans, because he is unable to enrol in any high school due to his average grades. Survival in the dangerous realm is difficult, as any humans found on school premises must be executed, but Tsukune chooses to stay despite the hazards for his love interest, Moka Akashiya.

Tsukune’s survival at the Youkai academy will undoubtedly remind fans of Issei from ‘High School DxD,’ who is unexpectedly thrust into a world of chaos and bloodshed. The protagonist also has various love adventures and sexually explicit meetings with gorgeous female characters in common.

3. Strike the Blood (2013 – 2014)

Kojou Akatsuki’s seemingly routine existence is turned upside down when he unexpectedly gets vampire powers after a bizarre incident. The Lion King Organization, aware of the deadly abilities that he will eventually learn, dispatches sword-shaman Yukina Himeragi to keep a check on him and, if necessary, execute the adolescent. To everyone’s astonishment, the couple ends up establishing an unlikely alliance to combat uncontrolled forces.

‘Strike the Blood’ and ‘High School DxD,’ both borderline hentai anime, include harem and ecchi aspects. Furthermore, the male heroes of the shows are transformed into supernatural beings who must gradually adapt to their newfound talents. As a result, if you’ve seen one of them, you’ll undoubtedly enjoy the other.

2. Demon King Daimao (2010)

‘Demon King Daimao’ follows Akuto Sai, an adolescent who enrols in the elite Constant Magic Academy with the ambition of transforming the world for the better. Unfortunately, once a prophecy reveals that he would become the Demon King, all of his expectations begin to crumble. He is quickly excluded from his social circle and left to fend for himself. With his newly awakened powers, Akuto resolves not to let the prophecies come true and decides to fight the prophecy in order to realise his dream of making the world a better place.

‘Demon King Daimao’ and ‘High School DxD’ share many similarities, including tonnes of fanservice moments, semi-nude sequences that raise the sexual tension to new heights, demon magic, harem, and ecchi aspects. While there may be some significant distinctions, the overlapping themes would undoubtedly make the former a fascinating watch for lovers of the latter as well.

1. Prison School (2015)

Hachimitsu Private Academy is a prestigious all-girls boarding school on the outskirts of Tokyo that has played an important part in developing the country via outstanding education. As a result, when it opens its doors to guys in the first semester, only five applications are accepted. Isolated and ignored, they attempt to intrude on the privacy of other students by attempting to sneak a glimpse of the girl as they take a bath, and are duly sentenced to the school’s prison after the famed Underground Student Council catches them in the act.

It signals the start of their harrowing struggle throughout their month-long confinement, which puts their bond and friendship to the test. Like Issei from ‘High School DxD,’ who becomes a servant, the five boys in ‘Prison School’ are enslaved in certain ways. Furthermore, both series are situated in a high school with voluptuous female characters and include a lot of provocative naked and semi-naked scenes. Funimation has the harem anime available.
