*Aggrieved pufferfish noises*

(no, I don't know what a pufferfish sounds like either)

Merman Zenitsu and pufferfish Chuntaro!

I was backing up some files earlier, and stumbled across this dumb AU doodle from a few years ago. Seemed appropriate to colour it with watercolours!

Cute little Chuntaro is a prickly pufferfish in this AU... but that raises the question: what marine species would the rest of the corps use to communicate underwater?

Swordfish are extremely fast swimmers, have convenient weapons/ letter clips stuck to their faces, excellent eyesight, are highly migratory loners with a massive range, and... ugh, fine. They're the obvious choice, aren't they?

Most members of the seaman slayer corps use swordfish.

Further fishy ideas beneath the cut:

Tanjirou:

My first instinct is to say sunfish, but the mental image of one of those massive creatures drifting menacingly behind him at all times is just too ridiculous.

And yet... somehow it makes perfect sense? A gentle giant that acts like a shield, patiently sheltering his sister from the sun whenever they travel near the surface.

Shinobu/ Kanao/Kanae: Butterfly fish, of course! All with polite and graceful personalities.

Shinobu fights using a variety of marine animal venoms including stonefish. Stonefish stings are treated with the applicaton of heat to denature proteins in the venom... so if Douma's an ice guy in this AU too, he's in for a rough time.

Inosuke: Briefly had a cute little pigfish, but he ate it within a day. Now he just has a regular corps- assigned swordfish. They're also tasty, apparently... if only he could catch it!

Tengen: Really wanted a Fireworks fish/ some other absurdly flamboyant tropical fish. Instead, he was assigned a bland- looking, tiny little fish that's well- suited to stealth missions.

It's been thoroughly ✨bedazzled✨by now and loves him. The most popular family member by far. Very plump and spoilt.

Gyomei: Green humphead parrotfish. These guys are massive, pretty docile, and spend most of their time crunching through rock- hard coral with big teeth to scrape off yummy algae, pooping out the rest as sand. They are cleaners that are instrumental in maintaining the health of coral reef ecosystems.

Gyomei's parrotfish is no exception; however, it used to be an insatiable glutton, to the point of destroying the coral reef it once resided in and being ostracised by its peers as a result. Wracked with guilt and with nowhere else to go, it received an invitation to serve in the corps. Its new master helped it learn self control.

Rengoku: There's no shortage of bold, flame- coloured fish species out there... but I reckon this guy just has the same generic swordfish species assigned to the rest of the corps. The only difference being that his used to be his father's loyal companion, and it's aged a bit, so it's not as speedy as it once was. It should've retired years ago, but refuses to abandon its self- imposed duty of keeping its master's son on the right path.

Was a rebellious playboy in its youth. Now it's a straight- laced military type, follows corps rules to the letter. Doesn't trust that slimy sea slug Nezuko one bit.

Sanemi: SAILFISH, hands down. Aggressive, vaguely wind- themed predator, and the fastest swimmer in the ocean. Both of them are pretty smug about that last point.

Genya: An archerfish would make sense thematically... but again, Genya just seems like another corps- assigned swordfish kinda guy to me? He definitely has a pet snapping turtle though. It's very small, and VERY grumpy.

Muchiro: A sweet natured blue- ringed octopus who wants nothing more than to be friends, but suffers from crippling social anxiety that makes it seem aloof and unapproachable.

Everyone is TERRIFIED of it except Tengen, who thinks it's flamboyant as heck, and Shinobu, who is simultaneously obsessed with it and wants to stab it dead.

Muchiro just ignores it, for the most part.

(Giyuu can relate).

Mitsuri: Blobfish lacking in self- confidence. Mitsuri thinks it's cute, and is absolutely correct in her opinion. Accepts cuddles from Mitsuri and Obanai only, and blushes at compliments. It's also insanely flexible, just like its master. Copes well under high pressure!

Giyuu: This man has a manta ray, no doubt about it. A creature of few words with a serene and peaceful disposition... yet inexplicably a huge social magnet that effortlessly draws everyone's attention (away from Giyuu). Especially popular with young merchildren, whom it often allows to ride on its back. Holds a deep respect for both its master and Urokodaki (who has a manta ray too, by the way).

Obanai: Had the toughest time deciding this one. A striped beakfish would match his colour scheme perfectly, but... I just don't think it suits him. A striped marlin, maybe? Anyone with more ideas, let me know!

Kaburamaru is a sea snake, obviously. A black- banded sea krait.
