* BreakoutCharacter: Yuudai, ''Yuudai,'' '''''Yuudai.''''' His sympathetic past, interactions with [[spoiler:(and later, crush on)]] Taisei, and versatility when it comes to being used in serious and comedic scenes alike has many readers declaring him as their favorite character.
* CargoShip: [[http://mynameismad.tumblr.com/post/18202219585/im-not-sure-why-i-drew-this Jiro and Cheepii, the Cheapies donut mascot]].
* CrackPairing: Taro and Yuudai. [[http://mynameismad.tumblr.com/post/13488765706/somebody-mentioned-something-about-shipping-these No, really.]]
* FanPreferredCouple: [[OppositesAttract TaiseixYuudai]] (affectionately titled ''[[PortmanteauCoupleName TaiDai]]'' in most cases), so much that the artist even talked about their popularity in a Lifestream. A lot of the fanart of ''Webcomic/{{Sakana}}'' out there is featuring those two.
** In a somewhat ironic turn of events [[spoiler: ''Taidai'' looks like it's on its way to becoming an OfficialCouple,]] with the result being that Jiro/Yuudai has now taken its place as a FanPreferredCouple.
* HilariousInHindsight: [[http://www.youtube.com/watch?v=qXkrR1kfQaw This movie]]. No, really.
* HoYay: Oh boy. Due to Taisei having NoSenseOfPersonalSpace, he ''oozes'' this. One example is his [[HeterosexualLifePartners bromantic]] relationship with Jiro (see there for more)
--->'''Taisei:''' [[ItMakesSenseInContext Did I try to ride you like a bike last night?]]
** [[DefrostingIceKing Yuudai slowly warming up to Taisei]] after Taisei repeatedly tries to befriend him with unfaltering enthusiasm, especially considering how [[CrushBlush awkward and blushy]] Yuudai is around him. After the brothers and these two have an excessive drinking night together, Yuudai loses his shirt and has to go home with Taisei's t-shirt on.
* JerkassWoobie: Yuudai openly hates most people and acts incredibly abrasive to his coworkers, but most fans are willing to forgive him since [[spoiler:he has trust issues courtesy of his [[DomesticAbuse abusive ex-boyfriend]]]].
* {{Moe}}:
** Jan [[{{Keet}} enthusiastically]] [[http://sakana.smackjeeves.com/comics/1067709/083/ presents the menu]], [[{{Adorkable}} awkwardly]] [[http://sakana.smackjeeves.com/comics/1098376/087/ waves]] with one hand in the background and [[http://sakana.smackjeeves.com/comics/1161376/097/ tries to say Taro's name]].
%%** Chie's friend Sango. Please add context before un-hiding.
* NightmareFuel: [[TheUnSmile The]] [[CreepyShadowedUndereyes face]] Taisei makes in the last panel of [[http://www.sakana-comic.com/comic/146 this strip]] is kinda creepy - even if we find out that it was just leading up to the first appearance of "business mode."
** On a more serious note, most scenes involving [[spoiler: Yuudai and Arata]] in the same room tend to be particularly anxiety-inducing. FridgeHorror, thy name is [[spoiler: Arata Tasaki.]]
