Mariko is sitting on the apartment balcony with her notebook, diligently writing out her thoughts for the day. She doesn't really feel like it, she's got a bad cold and would sooner lie in bed being brought miso soup at regular intervals, but she knows she'll feel better if she sorts out her thoughts even if those thoughts are mostly that she hates being sick, and wishes she could assign the part of herself that wants to do things literally every day come what may to her immune system its own body to do this for her.
Mariko crosses in front of her, pretending interest in a rack of belts.
Mariko goes on looking at belts. God these are expensive, don't these people have anything else to do with their money?
Mariko takes a picture of the belts for a plausible thing to have been doing in the store, then makes her way to the exit at a leisurely pace.
She keeps walking.
She goes home so she's still there when her mom gets in.
Yup. Mariko thinks she'll have a normal evening and sleep on it.
Oh good, it would be so disappointing if it weren't.
She goes to school, since she's no longer sick, writing down potential experiments in spare moments.
Her notetaking habit continues to give her a small amount magic. It seems to be giving her slightly more magic than before, though it's difficult to tell exactly. The magic almost seems, pleased, with the consistency of her habit.
Other acts of diligence throughout the school day also give her magic.
Well, that's simple enough to keep up, and if it likes how consistent she is she'll throw a little extra effort in that direction. Does this interact at all with contemplating her greatness?
All right then.
After school she goes for another walk, in a different direction.
And then she sees a child through the windows of an extremely fancy bakery. He is absolutely overflowing with reverse magic.
Huh, little kids can be wizards? Nifty.
She swings into the extremely fancy bakery and peers at extremely fancy baked things with her eyes and at the kid with her magic sense.
"That one!" he says.
"Ooh, and that one. And two of those. And three of those."
A young man, probably a high school student, enters the bakery and comes to stand behind him.
He is also full of magic, though to a less extreme extent. The magic filling him is mostly obverse with a trace of reverse.
Unlike the kid, he actually seems to notice Mariko and gives her an intense, scrutinizing look.
She can turn her magic into word-shapes. She writes Hi.
