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.
The twins call a car for themselves and all of the newly acquired clothes.
Mariko wears out one of the new outfits.
The twin's mom is in her studio, an enormous room full of costumed mannequins. Some of the outfits have faint traces of magic, but most are mundane.
Their mom is distracted working on some flowy silver thing that seems a mix between "dress" and "bikini", with the right half being the dress and the left haft exposing the wearer all the way up to directly under their bra.
"One moment," she says distracted.
He huffs and crosses his arms and waits.
"She's-" Hikaru starts to say and then stops.
"Wait," he whispers at Mariko, "how much can we actually tell her?"
"You're the ones who are supposed to know that!"
"Oh it's totally safe to tell her whatever."
"But it's your secret."
"I discovered magic on my own," she tells Hitachiin-san.
"Really," the twins chorus.
"I'm noticing that."
"I wouldn't want to be in trouble or anything."
"No she doesn't."
