G-On Riders

electric air wave

A list of anime containing ecchi elements, but are not tagged as ecchi by MAL. While the ecchi content may not be as prevalent or extreme as officially-tagged ecchi titles, there is still enough to be of interest to fans of the ecchi genre. Many of these register at least 1.5/3 stars on AniDB's "tag-weighting" system for ecchi.
Conversely, those who don't care for ecchi may wish to use this stack for cautionary purposes, as these titles may contain things like pantyshots, revealing outfits, incestuous overtones, oversized/jiggling breasts, swimsuit/lingerie moments, extended bath/shower scenes, lewd dream/fantasy sequences, innuendo, or general fanservice in an otherwise serious/"respectable" show.
Only the first seasons of franchises are listed. Some titles may (eventually) have additional details explaining why I've placed them on the list.

Lowest rated anime that are not based on anything, so it cannot be blamed to a bad adaptation.


The requisites is at least 6 episodes, and standard episode length minimum (20 minutes).

Stack Creator's Note: For the majority of them it's the first time I know about their existance.

Anime where there is a high female to male ratio, but the male protagonist does not develop a harem. The MC might date several characters in case it's a romance anime, but it never happens with more than one person at the same time.

Not adding Love Polygon anime.

Anime that start with a letter then the rest of the title, or have the letter separated from the title.

This stack contains all Deregula titles and anime tagged as "exclusive" on AnimeFesta.

From an ANN article on Deregula:
"WWWave Corporation launched the Deregula anime label in June 2023 to begin producing anime of other companies' IPs. Previously, WWWave Corporation had been focused on producing anime based on its own original manga. The company plans to release four new animated titles a year under the Deregula label while also continuing to produce its AnimeFesta titles at the same pace of at least four titles per year."
