It started simply. The woman was drawn away from her work by the rabbit, who had to tell the woman that the house was on fire.
The mistress of the house and the girl from the forest fought often, but the girl from the forest did not often become so enraged as to set the mansion on fire. She did not have bad blood with its other inhabitants.
But that evening, she had become so very mad.
"Hey, Mokou!" the mistress of the house taunted from her position on the roof. "You know, I've been thinking. You should really get over that grudge of yours!"
The girl from the forest lunged at the mistress of the house, fire spreading with her every step.
"I mean, come on. Your old man was kinda ugly as it is. And he was so old."
The woman did not hear that conversation between the two, and therefore was not there to witness the entire left sector of the mansion being lit ablaze.
She was, however, witnessing a substance like that of nothing she'd ever seen before. An ordinary resident of Gensokyo had brought it to her one day, but she had been busy and put it upon her shelf. That day, however, she had been doing spring cleaning, and had noticed the substance had nearly quadrupled in volume inside of its tiny container.
"Miss Eirin! Miss Eirin!" yelled the very frantic rabbit. "Miss Eirin! The house is on fire!"
The woman abruptly shoved her work aside and darted out the door.
"Udonge, go fetch Tewi and the other rabbits and tell them to start chanelling water to the house. I'm going to try and calm Mokou down-"
And that was that. For as soon as the jar tipped over, the troubles began.
The fire was put out relatively quickly, thanks to the massive number of rabbits and fairies living in the mansion.
Both the mistress of the house and the girl from the forest received smacks directly to the face, courtesy of the older woman, and the Human Village teacher came and removed the latter from the property.
It was, however, too late.
It was midnight by then, and the woman was feeling half-asleep.
As she crawled up in her futon, neglecting the substance from earlier, the last small fragments in the jar drifted out into the Gensokyo wind.
