* ''LightNovel/ShakuganNoShana'' - The later half

* ''LightNovel/SwordArtOnline''
* ''Anime/TamakoMarket''

* ''[[Franchise/LyricalNanoha Magical Girl Lyrical Nanoha]]'' - The MagicalGirl show that appeals to men, turning into something out of ''SuperRobotWars'' at some point.

!! Series sometimes mistaken for seinen

* ''Manga/BirdyTheMighty'': Originally began as a {{Shonen}} series in 1985 until it was cancelled in 1988. It became a {{Seinen}} series in its reboot. You can tell when it became a seinen where the [[ToneShift tone changes]].

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). Romance-wise, anything goes, from RomanticTwoGirlFriendship to obscure examples of BoysLove. In fact, SchoolgirlLesbians are a distinctive trait of [[YuriFanboy seinen]], rarely if ever present in shonen shows. 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]]". There is a reverse side to this, too: ironically, seinen is most infamous for its sub-category of ImprobablyFemaleCast and HaremSeries that rely heavily on cutesy {{Moe}} FanService (again, juxtaposed to plain sex appeal of female characters in shonen; see HotShounenMom, for example) to attract viewers. These series tend to be on the opposite side of the SlidingScaleOfIdealismVersusCynicism from the grim-and-gritty type of seinen, instead being [[LighterAndSofter fluffy, heart-warming, and comedic]].

Most of the anime stuff shown on Creator/AdultSwim and the [[{{Uncanceled}} revived]] Creator/{{Toonami}} is seinen, EXCLUDING the likes of ''Manga/InuYasha'', ''Manga/{{Bleach}}'', ''Manga/SoulEater'', ''Manga/{{Naruto}}'', ''Anime/IGPXImmortalGrandPrix'', ''Manga/DetectiveConan'', ''LightNovel/{{Durarara}}'', ''Manga/OnePiece'', ''Manga/FullMetalAlchemist'', ''Manga/DeathNote'', ''Manga/{{Kekkaishi}}'', ''Manga/DeadmanWonderland'' and (taking only the anime as reference) ''Anime/NeonGenesisEvangelion''[[note]][[WhatDoYouMeanItsForKids Yes, really.]][[/note]] which are shonen, but have very Seinen type themes.

* ''LightNovel/ShakuganNoShana'' - At least in the later manga adaptations.

* ''LightNovel/{{Baccano}}'' - while the original source material was targeted to a somewhat younger demographic like most other LightNovels, the anime is ''[[{{Gorn}} very]]'' graphic in its violence and aired on a satellite channel (WOWOW) best known for airing seinen and shows with adult themes and content.

* ''{{Manga/Bleach}}'' is still published in ShonenJump, and it's still advertized as a Shonen, but it has quite a few jarringly grim moments (especially in the later episodes/volumes).
