History Keet / AnimeAndManga

* [[ExtravertedNerd Umino]] from ''Anime/SailorMoon'' is pretty excitable in telling his buddies about stuff he's experienced, [[TheFriendNobodyLikes much to their annoyance]]. Even after he gets a RelationshipUpgrade with [[spoiler:Naru]], he still doesn't give up his excitable ways.

** A strange example from the same series: Yu Kashima is a woman, which would normally make her a GenkiGirl... except that she's also a massive {{Bifauxnen}} with the personality of an archetypal OtomeGame hero, including fitting this trope better. She's talkative, extroverted, competitive, somewhat immature, and younger than the main cast, even getting protective of her status as "the beloved [[SenpaiKohai kohai]]", while lacking the physical over-exaggeration and exhausting presence of a standard GenkiGirl.

* ''LightNovel/{{Baccano}}'':

* Eiji Kikumaru from ''Manga/ThePrinceOfTennis'', though he evolves more into a BunnyEarsLawyer as his character [[CharacterDevelopment develops]] through the series. Boys like [[GeniusDitz Jiroh Akutagawa]] and Gakuto Mukahi from Hyoutei Gakuen and [[DarkSkinnedRedHead Kintarou Tooyama from Shitenhouji]] fit more into the archetype.

* ''Anime/CuteHighEarthDefenseClubLove'': Yumoto, the shortest, youngest, most talkative, InTouchWithHisFeminineSide member of the Defense Club who'll jump into a hot spring fully clothed just because a fluffy wombat appeared out of nowhere. He's prone to being called [[FanNickname "blonde shota"]] because it looks like he was designed specifically for shotacons.

* Kimihiro Watanuki in ''Manga/XxxHolic'' is so Keet that eventually Doumeki stops bothering to tell him to quit being so loud and simply covers his ears when Watanuki inevitably gets overexcited. Or annoyed, which happens more often in Doumeki's vicinity. He steadily starts growing out of it due to CharacterDevelopment, and then abruptly ceases to be this completely when a certain major character dies.

%%** [[Anime/DigimonAdventure02 V-mon]] is a Genki, well, {{mon}}. [[FridgeBrilliance It's why V-mon's such a great match for Daisuke.]] - while Takeru's busy [[NotHimself not quite]] [[BerserkButton being his usual affable self]] in ''Anime/DigimonAdventure02'', Daisuke takes Takeru's place as the Keet.

* Mizushiro Hizumi from ''Manga/{{Spiral}}'' is "the Devil"... a very, very cheerful and cute one. When he isn't being murderous and/or unbearably angsty, that is - he'll switch between all three moods in a matter of seconds.

* Q-vier of ''Anime/ValvraveTheLiberator'' (cv: Creator/YuukiKaji) - a super-assassin BloodKnight with this personality. He's lived most of his life in a secret assassin-training facility and doesn't seem to realize that it's not normal to kill as frequently as you brush your teeth (to quote a [[Anime/CodeGeass similar character]] from the same writer). The result is unsettling, to say the least, and very sad.

** A strange example from the same series: Yu Kashima is a woman, which would normally make her a [[GenkiGirl Genki Girl]]... except that she's also a massive {{Bifauxnen}} whose personality is that of a stereotypical male lead, including fitting this trope better. She's talkative, extroverted, competitive, somewhat immature, and younger than the main cast, even getting protective of her status as "the beloved [[SempaiKohai kohai]]", while lacking the physical over-exaggeration and exhausting presence of a standard [[GenkiGirl Genki Girl]].

* Tendonman from ''Franchise/{{Anpanman}}''. He's the youngest, most traditionally cute-designed, and loudest member of the Donburiman Trio, and was the first Keet of the series, being introduced in the first episode before the other members of the trio.

* Laios from ''Manga/DeliciousInDungeon'' has his moments, usually when he's nerding out and squee-ing over [[NightmareFetishist monsters]].

%%* Akito from ''Manga/{{Air Gear}}''.

%%* Mizumachi Kengo from ''Manga/{{Eyeshield 21}}'' is 203 cm of sheer moxie.

* Yuri in ''LightNovel/KyouKaraMaou''. [[CrouchingMoronHiddenBadass Most of the time]].
* Otani from ''Manga/LovelyComplex'' is this quite often... awww.
* ''Manga/MahouSenseiNegima'':
** A good portion of the male student body falls under this (and the girls aren't any better). The final event in the previous year's Mahorafest was a campus-wide game of ''tag''. Which they aren't repeating this year because there were ''too many injuries''. They were down to a game of hide-and-seek when an army of robots shows up with [[ClothingDamage clothes-stripping lasers]]. So the teachers simply armed them with anti-robot magic guns and let them loose.
** Negi also qualifies when he's able to get away from his TrainingFromHell and responsibilities as a teacher. When he acquires a time machine during the festival arc and realizes he has enough time to do everything, he goes right into adorable-kid mode. His first impulse was to use the time machine to go back and see the dinosaurs.
