At the right times, the character interactions in Sakana can be just as heartwarming as they are hilarious. There's something really touching about an EnsembleCast of [[LoserProtagonist Loser Protagonists]] of all varieties coming together.

* Dear ladies and gentlemen, I present to you how Jiro and Taisei [[http://mynameismad.tumblr.com/post/10924561899/and-the-rest-is-history met.]] All together now: [[{{Squee}} Awwwwwwwww]]!
* Taisei doesn't seem the slightest bit put down by Yuudai's prickly exterior, and immediately thinks of him as a friend. Yuudai is understandably confused by this, though. Because seriously, Yuudai is always such a {{Jerkass}} to everyone, that he really doesn't have any friends.
** Taisei doesn't seem to be stopping any time soon, either. [[http://www.sakana-comic.com/comic/131 Once they're left alone,]] Taisei is still relentlessly cheerful and upbeat around Yuudai, even when talking about something as simple as his hair. Although, this doubles as a {{Tearjerker}} when Yuudai ends up snapping at him, mostly because his reaction heavily implies that people usually aren't this nice to him - not unless they have their own motives, anyway.
---> '''Yuudai:''' [[ObfuscatingStupidity I bet you've been playing dumb this whole time]]!! [[GossipyHens They probably talk all kinds of shit about me]] at home! About how [[JerkassWoobie I'm]] '''[[{{Jerkass}} mean]]''' and '''[[{{Tsundere}} difficult]]''' and '''[[DeadpanSnarker annoying]]'''. ...''Well?''
---> '''Taisei:''' Uhhhh... N-Not really? [[SubvertedTrope They're not very gossipy about work]].. And [[TheAlcoholic I'm]] [[CrowningMomentOfFunny usually drunk]]...so...
---> '''Yuudai:''' [[DramaticStutter W-Well]], why then? Why are you being so nice to me?! What do you want?!
---> '''Taisei:''' Nothing! I'm not even sure what you're talking about!
---> '''Yuudai:''' *[[LuminescentBlush blushing]]* ''Wait... you... You...Oh. '''Oh'''. Oh, uh... [[{{Tsundere}} S-Shit, I didn't...Uh... I mean, I'm so...]]
* Genji apologizing (after Taro already left, but still), after he had taken some money from Taro in a very unfriendly fashion, which showed that he really [[JerkassWithAHeartOfGold isn't such a bad guy]] after all, that he didn't lie about being in money trouble, and that he does feel genuinely sorry. After all, Taro already left and nobody would have heard him anyways, which makes it kind of a WhatYouAreInTheDark moment.
* [[http://www.sakana-comic.com/comic/152 Cutest strip ever or cutest strip ever]]? Made especially heartwarming due to Jiro's general bad luck with girls. You just want the guy to finally get lucky.
* Also counts as a CrowningMomentOfAwesome, but Jiro standing up to [[spoiler:[[HateSink Ara]][[BastardBoyfriend ta]]]] and telling him that [[http://www.sakana-comic.com/comic/281 he should leave the stall.]] And he's doing this for ''Yuudai,'' too. The guy's never been exactly [[{{Understatement}} easy to work with,]] and he's noted to have a special kind of hatred for Jiro, but [[NervousWreck Jiro]] himself knows that ''nobody'' should have to deal with someone like that.
** The fact that he also checks up on Yuudai afterwards, and takes the time to hear him out and talk about what happened. But this also doubles as a {{Tearjerker}}, since Yuudai initially thinks that Jiro only followed him to make fun of him.
* When Yuudai asks Jiro why he's so insistent on trying to see if he'd be at least good friends with Taisei [[spoiler:after he learns that Yuudai has a crush on him,]] [[http://www.sakana-comic.com/comic/339 Jiro gives a surprisingly profound answer]].
--> '''Jiro:''' I mean, you like ''him.'' The big, loud, excitable version of him. [...] [[spoiler:I don't think he's ever dated someone outside of work, but you like ''that'' Taisei,]] so... I think it's worth a shot at least! It could be a good experience for both of you.
** And [[http://www.sakana-comic.com/comic/336 this exchange]] from just a few pages earlier certainly counts. It's a bit more subtle than other examples, but as one commentator states, the fact that Jiro can recognize these qualities in someone who had been treating him like dirt for years has melted at least a couple of readers' hearts.
---> '''Jiro:''' Liking a shitty person doesn't automatically make you shitty.
---> '''Yuudai:''' Oh? So you'd say I've been a [[SarcasmMode generous and good-natured person]] to work with, right?
---> '''Jiro:''' Uh... No, I wouldn't use those exact words... But you ''are'' a hard worker. And you really care about your job. [[spoiler:And ''those'' are qualities that appeal to Taisei.]]
