Ooh, a Yaz Fadoula x aquaphilia reference!

But imagine the hours of riveting conversation you could have with him! His many varied interests! His nuanced takes on world events!

Congratulations!

My submission: Monika from Doki Doki Literature Club underwater, under a clear plastic cover like this.

There was a swimming pool scene written for her during her Doctor Who days but she couldn't swim at the time, so the scene was scrapped.

So the closest we've ever gotten is this (or AI, *cough*).

Way too many to mention, but to simplify:

Animated: Any of the girls from Doki Doki Literature Club

Live Action: Ruby Roundhouse from the Jumanji movies

Change your account, this is now a breakfast cereal focused account.

The old AquaFans video "Casting Call", where Maggie is held under by a film director to test her breathhold time, but he gets distracted and she drowns, all while she desperately tries to escape.

I'm getting to this a bit late...but if you need another character, how about Monika from Doki Doki Literature Club masturbating as she holds herself under until she succumbs to the water.

Oh yes, the girls from Chaos Theory/Camp Cretaceous need to be in drowning peril a lot more.

Komi from Komi Can't Communicate would be a good candidate to blub.
She can't communicate if she's out of air underwater, y'know.

Vibes

Oh yes, this is an extremely hot idea.
