Top 18 Ecchi Anime to watch

Fan service is found in many anime, in many forms. When the service has a distinctly sexual slant to it, and it appears to be a major focus of the show, then it's safe to assume you're watching ecchi. The word "ecchi" is used by English-speaking anime fans to refer to soft-core pornographic or sexually suggestive anime and manga. This is a western invention; in Japanese, it is a catch-all term for all things anyhow sexual in nature, not being limited to porn, but also not really considered a "milder" term, as it may also refer to sexual intercourse itself. The term "ecchi" in Japanese comes from the pronunciation of the letter "H" in English, which is rendered into Japanese syllabary as エッチ, which in turn is transliterated in the English alphabet as "ecchi" or "etchi". It is not, as many believe, short for "hentai" -- that, too, seems to be a western invention. It is, however, nearly as misunderstood and misapplied a term as "hentai".The line between ecchi and hentai, from the western perspective over these terms, can be hard to draw at times; one good rule of thumb is: if it was aired on Japanese public TV at all, it probably wasn't hentai. Ecchi usually features all the specifics to human anatomy that can only be found in anime, and generally avoids full nudity, instead abusing of panty shots. Hentai, on the other hand, will usually show full frontal nudity in some explicit form, including genitalia, and full, intimate sex scenes. At its mildest, ecchi is composed of double entendres, big misunderstandings, and sexual farce; at its most explicit, it is still in the realm of softcore pornography, with full breast shots, full back nudity and similar content, but no display of genitalia. Another good way to distinguish the two is looking for animated sex scenes; if one is found, you have generally left the genre entirely, though a few borderline exceptions apply here. For Kitsu's purposes, the distinction between explicit ecchi and actual hentai is simple: if it was sold with an 18+ restriction in its country of origin, it is hentai; if it was sold without it, it is ecchi.

1. Nanatsu no Taizai

In a world similar to the European Middle Ages, the feared yet revered Holy Knights of Britannia use immensely powerful magic to protect the region of Britannia and its kingdoms. However, a small subset of the Knights supposedly betrayed their homeland and turned their blades against their comrades in an attempt to overthrow the ruler of Liones. They were defeated by the Holy Knights, but rumors continued to persist that these legendary knights, called the "Seven Deadly Sins," were still alive. Ten years later, the Holy Knights themselves staged a coup d’état, and thus became the new, tyrannical rulers of the Kingdom of Liones.

Based on the best-selling manga series of the same name, Nanatsu no Taizai follows the adventures of Elizabeth, the third princess of the Kingdom of Liones, and her search for the Seven Deadly Sins. With their help, she endeavors to not only take back her kingdom from the Holy Knights, but to also seek justice in an unjust world.

3. No Game No Life

No Game No Life is a surreal comedy that follows Sora and Shiro, shut-in NEET siblings and the online gamer duo behind the legendary username "Kuuhaku."

The mysterious god welcomes Sora and Shiro to Disboard, a world where all forms of conflict—from petty squabbles to the fate of whole countries—are settled not through war, but by way of high-stake games. This system works thanks to a fundamental rule wherein each party must wager something they deem to be of equal value to the other party's wager. In this strange land where the very idea of humanity is reduced to child’s play, the indifferent genius gamer duo of Sora and Shiro have finally found a real reason to keep playing games: to unite the sixteen races of Disboard, defeat Tet, and become the gods of this new, gaming-is-everything world.

As they learn to use these powers and settle in, their lives as everyday students will be far from normal.
