History Main / Seinen

* ''Manga/{{Hen}'' (serialized in ''Weekly Young Jump'')

* ''Manga/{{Mono}}''

* ''Manga/{{Fable}}''

* ''Manga/MagicalTarurutoKun'': The manga was created by ''Golden Boy'' creator Tatsuya Egawa, who's output before and since both series has mostly consisted of seinen series. Despite its lewd and FanService-filled nature (specifically uncensored nudity and breastfeeding) and early on and the fact that its English publisher lists the series as a seinen manga, not to mention its title character looking like something ripped out of a {{Kodomomuke}} series, it ran in ''Weekly Shonen Jump''.

* ''Webcomic/OnePunchMan'' (Creator/YusukeMurata remake) - Despite being localized under the Viz' Shounen Jump label, in Japan it is published in ''Tonari Young Jump'', the online version of Weekly Young Jump.

* ''Manga/WorldsEndHarem'' is about the entire male populace dying, save the protagonist and four other men, with the remaining women urging them to impregnate them by thousands, even enforcing that artificial insemination doesn’t work so they are forced to do the nasty, nasty; the women wear varying levels of fetishistic clothing and they all have top model looks, bare breasts are seen a lot. Everything is drawn by a famous hentai artist to boot. The series runs in an online offshoot of Shounen Jump; however, some of the {{spinoff}}s such as ''Manga/WorldsEndHaremFantasia'' are, in fact, seinen.

* ''Manga/SinnerInTheSeabed''

* ''Manga/BokuraWaMahouShounen''

* ''Manga/{{Sanctuary}}''

* ''Franchise/LyricalNanoha'' is a MagicalGirl franchise which is aimed squarely at adult men, especially since later entries tone down the magical girl elements in favor of more sci-fi elements. Its multiple manga adaptations, sequels and spinoffs were serialized in ''Megami Magazine'' and ''Nyantype''.

* ''Manga/{{BECK}}'' has many realistic aspects found in seinen, but it ran in Monthly Shonen Magazine.

A typical seinen protagonist can be of any gender and [[CoolOldGuy age]] (in stark contrast to shonen, whose protagonists are almost exclusively young and male), but tend to be young adults (like its target audience). Romance-wise, anything goes, from PseudoRomanticFriendship to obscure examples of BoysLove. In fact, lesbian characters are a distinctive trait of seinen, rarely if ever present in shonen shows, since many readers of seinen manga are {{Yuri Fan}}s. Relationships are portrayed in a less idealistic light than in shojo, with many grays and uncertainties like in RealLife, and don't tend to indulge the shonen over-simplification of "[[BettyAndVeronica which heroine]] will be [[LastMinuteHookup hooked up with the hero]]". Seinen series are also known for the controversial and divisive sub-category of ImprobablyFemaleCast and HaremSeries that rely heavily on cutesy {{Moe}} elements (again, contrasting with the more blatant {{fanservice}} focused on female characters in shonen) to attract viewers. These series tend to be on the opposite side of the SlidingScaleOfIdealismVersusCynicism from the grim type of seinen, instead being [[LighterAndSofter fluffy, heart-warming, and comedic]].

* ''Franchise/{{Devilman}}'' and its first sequel ''Manga/ViolenceJack'', made by Creator/GoNagai. Both series contains gorn and nudity and it ran in ''Weekly Shonen Champion''. ''Violence Jack'' however moved to a different magazine after complaints of its violence nature. Other sequels, remakes, and re-imaginings are also Seinen.

* ''Manga/DeadmanWonderland'' - It has a dark storyline and some glaring {{gorn}}, it runs on many a TraumaCongaLine, yet it runs in a shonen magazine.
* ''Manga/DeathNote'': Due to being a [[SlidingScaleOfIdealismVersusCynicism largely cynical]] crime story with a VillainProtagonist and WhatDoYouMeanItsForKids, it just has MultipleDemographicAppeal. That said, Light Yagami himself is considered a typical shonen hero, albeit a heavily Deconstructed and realistic one. It ran in Shonen Jump. The authors have also said that if the manga were to run in a seinen publication, they would have focused more on the effects of the Death Note on the world and on the question of whether TheExtremistWasRight, rather than on the cat-and-mouse game between Light, L, and Near.

* ''Manga/FistOfTheNorthStar'' due to its violent content. Also ran in Shonen Jump. ''Manga/FistOfTheBlueSky'', ''Jibo no Hoshi'', and ''Hōkō no Kumo'', among others are genuine seinen.

* ''Manga/FutureDiary'': Violent, horrific and containing adult themes and situations. It ran on Shonen Ace. Its spin-off, ''Future Diary: Paradox'', is seinen.

* ''Manga/{{Sukaraiti}}''

* ''Manga/Sukaraiti''

* ''Manga/ABouquetForAnUglyGirl''
