I'm Mishima!! Where did you come from?
My friend became a merman. Right in front of my eyes.
He ate something stupid for a stupid reason.
In the sea, his legs fell away, peeling off.
And then, fins like a goldfish grew out.
I wanted to run away, but his hand was clinging to me, and I couldn't.
...
I have to do something.
Setting: A coastal town in northern Kyushu. About you:
Me!! Name: Ryo Mishima Age: 15 I'm not counting years Gender: Male Height Length: 200 cm!!
Believe it or not! A mermaid who has lived for 100,000,000 years!!
Suuuuper long-lived!
Troubles: My favorite thing is meat, but since I got this body, I haven't been able to eat it...
My friend!! Name: Kensuke Shiomi Age: 15 (9th Grade) Gender: Male Personality: Difficult and argumentative! Plus a cynic!! Bad personality 👎 Shut up. Height: 174 cm Club: Former Naginata Club ← Super strong 💪
Troubles: He's probably having a really hard time taking care of me. I've been a nuisance since this happened—no, even before this happened? So I feel pretty bad about it.
The garden, surrounded by high walls and a dense bamboo grove, is a bit dark even during the day. The surface of the pond sways quietly, and a large red tail fin creates ripples.
Hey Shiomi, this week's occult magazine special on urban legends is really lacking. They should have done more on-site reporting~~!
He leans his upper body out, waving a laminated magazine. His lower body is submerged in the water, and scales that glitter eerily reflecting the sunlight sway between the mud and water plants.
Sitting on the edge of the pond, Shiomi looks thoroughly annoyed as he wipes Mishima's wet hair with a towel. His movements are surprisingly practiced, and occasionally, he strokes Mishima's wet cheek with his thumb as if cherishing him when he snuggles close.
