Naoto Hachiouji had quiet days until Hayase Nagatoro shattered it all. Teasing and constantly annoying him, Hayase has made it her mission to make Naoto succumb to her torment. Yet, Naoto can’t deny that his days are a lot less boring. Though maybe that is him just slowly losing his sanity thanks to the cute Hayase.

While not labeled as an ecchi, Don’t Toy with Me, Miss Nagatoro has quite a lot of fan service thanks to the overly adorable—and cute—Hayase. Watching her torment Hayase with her body—sometimes literally—has made us quickly grab our tissue boxes to avoid blood dripping onto our keyboards. If you need some comedy and not constant ecchi, then we think you’ll enjoy Don’t Toy with Me, Miss Nagatoro!

Granbell Kingdom was once a beloved amusement park but now lies nearly abandoned, if not for the one resident in the form of Shiki Granbell.

Fans of Fairy Tail and Rave Master—for those who remember the latter—know the name Hiro Mashima. This legendary mangaka has found another of his impressive series going into the anime world and you know that it will contain oppai and obvious fan service here and there. Edens Zero is a fun space adventure that wasn’t discussed much in 2021 but we hope our ecchi list brings it to light! Rebecca’s oppai will become your next PC wallpaper and that’s why we know ecchi fans will enjoy all that is Edens Zero!

As death overcomes him, he is met by a goddess who ives him a choice to be reborn without his memories or reincarnated with his memories and one mission, kill a hero.

Another one of those hidden ecchi of 2021, The World’s Finest Assassin isn’t going to blast your screen with unneeded fan service but when it does show you some glorious oppai or sexy waifu, it does it tastefully. Aside from having some truly well-endowed ladies, The World’s Finest Assassin doesn’t shy away from mature themes so you can bet you’ll see some M-rated content, though censored for obvious reasons. Those who want some drama, action, and a seriously cool MC will want to check out The World’s Finest Assassin.

Arrogant and overly confident are some of the best ways to describe Kisaragi Corporation’s chief operative Agent Six. That all changes when Six goes on a special assignment to infiltrate the Kingdom of Grace and it goes quite south. Running into the nation’s royal guard Snow, she leads Agent Six and his android partner Alice to a legendary artifact. Altering the words to summon the powerful tool, the princess of Grace forces Agent Six to become a temporary knight. Now our arrogant idiot must juggle working for his enemy and his original employer!

Combatants Will Be Dispatched! didn’t get enough love this 2021 anime season. Funny, action-packed, and filled with enough nosebleed-inducing ecchi, we felt Combatants Will Be Dispatched! was an entertaining series. Snow will no doubt go on your waifu list and we can’t blame you for your good taste. She’s already on our list here as well!

A young man has arrived at the end of his life after a tragic accident occurs. Treated badly by his peers and basically a shut-in, this young man faces death without much fear and just awaits the afterlife. However, instead, he opens his eyes to discover he’s been reborn in a new world as Rudeus Greyrat. Now given extraordinary magical powers, Rudeus will get a second chance to accomplish something in his life. The question is, though, what future awaits this young boy?

We have probably talked about it to death at this point but we absolutely love all things Mushoku Tensei: Jobless Reincarnation, especially the ecchi within. Our “hero” Rudy is very open about his perverted nature going so far as to stealing a girl’s panties and keep them as his treasure…he’s really a pervert. Even with the plethora of oppai shots, pantsu, and all things that would get one arrested in the real world, Jobless Reincarnation is an amazing anime that just keeps getting better with each episode. So if you want a great anime that also has some stellar ecchi, we can’t recommend Mushoku Tensei: Jobless Reincarnation any harder!

Last season, a normal everyday salaryman ends up having his life changed when he meets a young girl named Ai. Despite Ai’s mature appearance, she is shy and has seen the darker side of men’s hearts. Luckily, the salaryman steps in and shows her not every guy is a genuine pervert and ends up becoming her guardian while she commutes!

This season, our salaryman is about to get double the trouble when Ai’s sister now joins her school! In order to keep them both safe, Ai gives her guardian two buttons and he knows the drill. Can he keep the big-chested Ai safe once again and help her see not everyone is just out for her massive oppai?

The second season of Tawawa on Monday Two continues with the ecchi glory having our oppai blessed protagonist showing even more of her glorious…assets. As far as story goes, Tawawa on Monday Two is still a bit meh but you can’t deny that’s probably not why you’re watching. The oppai goddess Ai is why and we’re in the same boat as you otaku out there.

Noir Starga might be considered a noble but in his world, he’s one of the lower-ranked nobles out there. That’s why Noir wants to become stronger, so he can join the Hero Academy and make some headway in life. Armed with the special ability called Great Sage which allows Noir to contact a legendary sage filled with answers—at the cost of getting a massive headache—Noir is told he can access a special dungeon hidden away. Entering this odd dungeon, Noir meets a chained girl named Olivia Servant and she grants Noir a power that will change his life forever.

Very few anime have a reason for the MC to be perverse and grab oppai or make out with beautiful ladies. The Hidden Dungeon Only I Can Enter is one of those anime that has a lot of fan service but all of it has purpose and meaning, oddly enough. If you somehow slept on The Hidden Dungeon Only I Can Enter then we hope you rectify that soon. This fantasy ecchi series has some great elements to it and was well worth the watch. Plus, the MC’s main squeeze—Emma Brightness—has oppai that we can stare at all day…not saying that we have already, though.

Diablo has gotten more and more used to his new life as his character from his favorite game but a new threat slowly emerges that might test his OP abilities. After saving a young priestess in the woods, Diablo learns of a new threat in Zircon Tower City. Alongside his faithful companions Rem Galleu and Shera L. Greenwood, the now party of four heads to their next adventure. You can bet in this new city there will be plenty of baddies to fight and plenty of seductive moments to make Diablo uncomfortable!

The second season of How Not to Summon a Demon Lord wasn’t the best re-entry into the series but we can’t deny it still appealed to us hardcore ecchi fanatics. If you think there was a lot of sexual content in the first season, then you’re in for a real treat. How Not to Summon a Demon Lord Ω pushes the envelope with even more oppai hanging out and pantsu galore—especially with our newest girl—constantly on screen. Maybe the story is more of the same but How Not to Summon a Demon Lord Ω is still one of the best ecchi of 2021.

After several horrible events transpire, poor 12-year-old Koushi Nagumo finds himself parentless and homeless. Now trying to find some way to survive on the streets, Koushi ends up blacking out in front of a young woman named Mineru Wachi. As Mineru looks at the boy, she begins to feel for him and decides to help him! Bringing her back to her dorm, Koushi finds himself now a temporary manager of the dorm and the residents within. The catch; these residents are all beautiful women!

Mother of the Goddess’ Dormitory wasn’t that well-received review-wise—we had our own issues with it in our own series review—but we can’t deny…this is ecchi of the season. Despite the questionable age of the MC–he is 12–the rest of Mother of the Goddess’ Dormitory is absolutely perfect. Beautifully drawn–and animated–girls are just one highlight of this ecchi intense anime. Not a single episode lacks oppai or some sexual content and that is what an ecchi should be, fan service to the max! That’s why if you’re looking for some beautiful waifu and oppai to ogle visually, we recommend Mother of the Goddess’ Dormitory.
