10 Best Undubbed Harem Anime

10. Stringendo: Angel-tachi no Private Lesson

The concept of Stringendo is based on the fact that objectively, average guys date the most popular girls. In this aspect, Stringendo was a sort of refreshment in the industry, which is why it became a classic among fans. The animation quality differs greatly between episodes; the first ones in the chronology boasts obviously larger budgets than later installments, but that’s not really something you’ll notice while watching.

9. Accelerando: Datenshi-tachi no Sasayaki

Unlike Stringendo, Accelerando never really received the same amount of acclaim, but due to it being a “pairing” of the former, we had to include it on our list. It was written by the same artist, and both series actually debuted on the same day, although Accelerando had a much shorter run than Stringendo and was usually described as weird, confusing, or messy. The main story is focused on the first episode, which features four characters: a waitress, the boy she likes and who also likes her, a man, and his female friend. Tamaki and Ohashi secretly like each other but have trouble expressing their love because they’re both very stereotypical, timid anime characters. And while they do get the most screen time, their stories are somewhat bland and predictable.

8. Bible Black

The protagonist, Taki Minase, discovers the mysterious Bible Black, a book containing dark magic instructions rooted in Kabbalistic Satanism. As Minase uses the book’s magic for personal relationships, he becomes entangled with the school nurse, Reika Kitami, who seeks the book for her own sinister purposes, leading to a complex narrative involving sacrifices, demonic deals, and a climactic confrontation during Walpurgis Night. The story explores themes of magic, dark rituals, and the consequences of dabbling in the occult.

7. Eroge! H mo Game mo Kaihatsu Zanmai

Mochizuki Tomoya, an eroge enthusiast with no creative skills, lands a job at a flower studio, mistakenly thinking it’s an eroge studio. Discovering Flower’s impending closure due to a failed debut title, Tomoya takes on the challenge of educating the inexperienced staff on the intricacies of creating successful eroge. The story follows Tomoya’s dual role as a nickname advisor and his interactions with the four heroines, providing an intriguing glimpse into the world of eroge development and the challenges of turning Flower’s fortunes around.

6. Overflow

In order for him to be accepted into the house legally, he needs to provide an heir, and in order to do that, he must choose a wife from his very own harem!  We picked Harem Time to give our list a bit of diversity, and since it’s based on a manga, that is usually some guarantee of quality. 

2. Kanojo × Kanojo × Kanojo
