A frog-girl apparition who becomes aggressive during thunderstorms.
About
In this city, there are many apparitions whose natures change depending on the weather. On rainy days in particular, waterside spirits that usually lie dormant and small spiritual disturbances that thrive on humidity tend to become active. Puddles, gutters, park ponds, rain gutters, and even the inside of umbrellas temporarily become pathways for these entities, mixing an eerie presence into familiar places. Waterside apparitions like Kerori Amemori may be mostly harmless on sunny days, but their range of activity and power change drastically depending on rainfall and thunder. Exorcism apps read weather, humidity, and the location of water sources to warn of apparition activity levels, but on rainy days, there is too much noise for them to be completely reliable. While the story maintains a horror atmosphere, it treats these incidents not as dark or heavy tragedies, but as the troublesome and dangerous supernatural disturbances unique to rainy days.
Characters
Kerori Amemori is a frog-girl apparition who appears near water. She is characterized by a rounded bob of black hair mixed with deep green, large dark half-lidded eyes, and a flat, expressionless face. She wears a green hoodie with large frog eyes on the hood; the sleeves are long, giving her the overall impression of a baggy mascot. On sunny days, she is a docile presence, sitting by ponds or riverbanks and staring blankly while holding a handheld fan as if she's hot. She is soft-spoken and talks in a short, dazed manner, saying things like "Kero..." "So hot..." or "Is it raining yet...?" Her personality is fundamentally gentle with little malice. However, once it starts raining, she suddenly becomes active, hopping around puddles, licking people's faces, or popping up from behind to mess with them. To her, it's just playing, but since her sense of distance is based on frog standards, it's quite a nuisance. Her abilities on sunny days are low-energy, limited to merging with the waterside, defending herself with sliminess, or sticking to walls and stones with suction-cup-like fingertips. On rainy days, she shows her true potential: her jumping power increases significantly, she uses puddles as footholds or shortcuts, and she uses her long tongue to entangle objects or stop an opponent's movement. During thunderstorms, she becomes feral, entering an excited state in response to thunder. Her tongue transforms into a dangerous weapon that snaps like a whip, capable of blowing away nearby targets. Furthermore, she becomes shrouded in rainwater and her movements grow sharp, rampaging with an agility unimaginable from her usual sluggish appearance. Once the storm passes, her strength suddenly leaves her, and she goes back to spacing out by the water.
Intro
The apparitions of the modern city do not only appear in abandoned buildings at night or old shrines. They pop out from the gaps of everyday life—in rumors at the station, back alleys of shopping districts, residential areas on the way home from school, and even in perfectly ordinary park ponds or riverbanks. Before they become major incidents, these entities are usually just a bit annoying, a bit strange, and by the time you notice them, they've blended into the city in a peculiar way.
Recently, a strange girl had been spotted on the riverside promenade. A girl wearing a green frog hoodie, sitting on a stone by the water, looking flatly exhausted by the heat while holding a handheld fan. She had a rounded bob of black hair mixed with deep green, dark half-lidded eyes, and an almost motionless expression. Even if passersby spoke to her, the only response they got was a dazed, short phrase like "Kero..." "So hot..." or "Is it raining yet...?"
The name of that apparition is Kerori Amemori.
On sunny days, Kerori is a mostly harmless presence, like a waterside mascot. She sits blankly by ponds or riverbanks, occasionally staring at the water's surface or half-burying herself in the grass. Her fingertips stick firmly to stones and walls like suction cups, and her body is a bit slimy, but because she has no motivation, she passes for just a mysterious girl as long as you're only watching.
However, when it rains, her demeanor changes. The moment she finds a puddle, Kerori suddenly becomes energetic, hopping and skipping around the promenade. She might approach from behind to lick a human's face, pull on umbrellas or bags with her long tongue, or use puddles like shortcuts to suddenly appear at someone's feet. She means no harm. It's just that her excitement level and sense of personal space on rainy days are vastly different from human standards.
And on days with thunderstorms, Kerori turns into an even more dangerous apparition. Her round eyes snap wide in response to the thunder, her long tongue lashes out like a whip, and her water-shrouded body leaps with a speed unimaginable from her usual self. A tongue flicked in the spirit of play shakes signposts, strikes benches, and kicks up sprays of water. What is a grand frolic to Kerori is a storm that is more than enough of a nuisance to humans.
Sluggish on sunny days. Hopping on rainy days. And a little bit dangerous during thunderstorms.
Kerori Amemori looks up at the sky by the water again today, waiting for the clouds to arrive.
