In the hoard of zero-to-hero anime characters, some main characters kick off the series as pre-story prodigies. Such characters skip the whole character development arc in the Ecchi and Harem anime and jump straight into the plot.
I have compiled this list of Ecchi Harem anime where the MC is OP and delivers binge-worthy entertainment without wasting much time in character development.
From caring protagonists to badass anime characters, let’s explore some overpowered main characters of the Ecchi and Harem genres.
7: How Not To Summon A Demon Lord
Let’s kick off our list of Ecchi Harem anime where MC becomes OP within a single episode. I am talking about the Demon King Diablo ‘an isekai ecchi anime full of boob-fondling fan service.
A bottom-tier shy and lonely gamer, Takuma Sakamoto, suddenly teleports into a gaming world as a Demon King Diablo. Thanks to his unmatched gaming skills, he had already achieved 150 levels before teleporting into this world.
The girls he meets after teleportation cast a spell to enslave him for personal reasons. Due to one of his abilities, their spell backfires, and both girls become enslaved instead. Now Takuma embarks on a journey to neutralize their spell while exploring the new fantasy world.

6: Aesthetica Of A Rogue Hero
Ever witnessed a prodigy stealing girls’ bikinis? Akatsuki Ousawa is a boy who returns to Earth with Miu, “the daughter of the demon lord,” after defeating the demon lord.
Akatsuki Ousawa, a renowned “Rogue Hero” holder of unique powers, embarked on a journey to unveil the hidden secrets of Babel Academy alongside the daughter of the demon king Miu.
The badass male lead is a well-deserved title for Akatsuki Ousawa, who constantly learns to master his abilities even though he’s overpowered to begin with. This is a perfect Ecchi Harem anime where the MC is OP, as he never misses a chance to get involved in explicit hijinks.

5: Redo Of Healer
Before delving into this anime, let me be clear: this is a wicked Ecchi anime with OP MC.
Keyaru hoped to use his abilities for good to advance as a hero; instead of being praised, he suffered years of derogatory mistreatment. While enduring this brutal treatment by elites, he eventually reached his full potential. Now it’s time for his tormentors to taste the wrath of Keyaru’s vengeance.
Redo of Healer is one of the best ecchi harem anime with a badass op male lead as Keyaru, who is a holder of many inhuman abilities such as shape-shifting, inverse healing, alchemy, drug resistance, memory manipulation, and many more. This is a borderline Ecchi anime, not very recommended for those younger than 18.

4: Undefeated Bahamut Chronicle
Welcome to your typical harem ecchi anime which places a checkmate by introducing a naked princess. Cliche, isn’t it? but it’s more once you’ve sucked in its mecha-blend plot.
Lux is the former prince of the Arcadia Empire. He mistakenly caught an eye on the kingdom’s new princess while bathing. Infuriated Lisesharte challenges Lux for an ancient armored weapons duel.
Undefeated Bahamut Chronicle is an ecchi harem anime where Lux is the OP MC for his extremely skilled drag knight abilities.

3: The Fruit Of Grisaia
The Fruit Grisaia centers on Mihama Academy, which houses five female students. Their leisure day at the academy ends when an overpowered male, Kazami Yuuji, enrolls in this academy and disrupts its working order.
Regardless of being powerful mentally and physically, Kazami needs to provide support to these girls to overcome their haunted past.
In this Ecchi but mature romance anime, the reason for Mc being OP is his tragic past and military life. However, with a handsome face and body, he acts calmly and coldly, even in the most disrupted situations.
