There's That Time
Under falling snow, a yu~ yu~ voice can be heard from the alley. Almost certainly this is a yukkuri. The Marisa finally creeped out to the street and saw a man passing by. Weakly, she greeted the man.
This man is a yukkuri lover. He did kill a lot of yukkuri, but he also often took strays and raise them into gold badge pets. He's rather surprised that the yukkuri greeting him is a Shell Marisa. He greeted back and Marisa's face brighten a bit.
Too bad, he doesn't feel like raising a Shell Marisa right now. She's a rare type, surely someone else will take her as pet.
Marisa crawl again and meet different human, but all their reaction is the same. They're interested in the Shell Marisa who hasn't show up lately, but nobody is interested in taking her as pet.
About two or three years ago, Shell Marisa is really popular. Even as a mutation from Marisa type, they're recognized as rare types. Even their personality are like rare types who are mostly nice.
In the natural world, Shell Marisa is popular among other yukkuri. They're treated as idol.
You can say that being born as Shell Marisa will guarantee their bright future.
But time changes. Back then, what's called rare types are limited to Remirya, Fran, Ran and Yuuka, then Shell Marisa. But these days, many new rare types has shows up, such as the Yoshika type that cost an arm and leg to buy. The popularity of old rare types has diminished.
Moreover, industry has managed to mass produce Shell Marisa, which saturated the market and cause a fall of their price.
Shell Marisa is slow and although they had better water resistance, they could end up melting in water because of that slowness. As they grow big, their shell became heavier and unwieldy for their pet owner. It can be said that the only value of Shell Marisa is simply "they're niceheads".
To make things worse, training methods has advanced. These days, it's very common to find real gold badge yukkuri in the pet shop. With that, if you can get a gold badged well-behaving Marisa with just a little more cost, why buy Shell Marisa with all their limitation ? Because of this, popularity of Shell Marisa quickly drifts away among the rare types.
Marisa cried. Human has disappeared from the road and snow stacked thicker and thicker.
Marisa cried. Why should she ends up like this ? She's special. She's a good kid. She doesn't pick a fight, can use the toilet, count to 100, eat only when allowed. She don't want to die.
Next morning, without melting, her face is frozen in expression of ghastly anguish.
A nameless abyuser found her and take her to decorate his home.
The author also mentioned he noticed that Shell Marisa hasn't been showing up these days.
