Toshiaki had a pet yukkuri Marisa. This Marisa is smart and what she likes the most is to write and draw. First she tried reading newspaper, and then mimic her owner when writing.
After being taught, Marisa can already write and read in hiragana. She also learned new vocabularies. Her owner guessed she's about as smart in it as kindergarten or first year kid.
One day, after a sudden job call, Toshiaki found his house dark. He thought Marisa is asleep, but when he turned on the light, Marisa greeted him.
The wall and floor is full of writing.
At first, he's mad, but he realized it's his fault to not tell Marisa to write only on papers.
Marisa, feeling guilty, tried licking to erase the text, but she has used an oil marker mixed with the other pen so she can't.
Tired, Toshiaki told Marisa to sleep while he took some leftover thinner to wipe clean the writing on floor and wall. This is a rented apartment, so he will have to make sure everything is as it is when he returned it.
After finishing half, he went to sleep.
Next morning, smelling thinner in the house, he quickly run to the living room. There, Marisa vomitted her paste and laying on her side. Next to her is the empty thinner can.
Quickly he bring Marisa to the hospital. The doctor said her life is safe for now, but she won't return to who she was. The thinner has damaged her paste core too much.
Back home, Marisa is no longer her energetic self. She almost never speak, only making sound while rolling slightly. Toshiaki had to wipe her poo poo and pee pee everyday after work and spoon food to her.
Sometimes, Marisa could greet Mister, but it's more instinctual and Marisa no longer remember her owner.
Sometimes, Marisa would jump around, slamming herself to the wall. To avoid injuries, Toshiaki taped cushion to Marisa.
Finally, one day Toshiaki is awake and found Marisa not in her cage. In the living room, Marisa crumbled down and turns black.
Next to her is a paper with repeated writing.
