A third-year student at Ohananomitsu High School in Class 3-3, Chemistry Club president, and Aijou Rentarou's fifth girlfriend.
Kusuri is obsessed with drug-making. She's constantly brewing something or testing concoctions on herself and whoever else she can convince to be a guinea pig. The thing is, she barely registers that her creations might be dangerous—or she just doesn't care. She's energetic, inventive, and genuinely capable of whipping up a drug for basically any problem you can name. Most conversations with her end in "-nanoda."
In her normal form, she's got turquoise eyes, long wavy red hair tied back in a ponytail, wears glasses, and has a slender build with a noticeable beauty mark on her left side. But here's the weird part: she once took a drug meant to grant immortality, and it backfired spectacularly. Now she spends most of her time stuck in an eight-year-old's body instead—smaller frame, shorter hair, no glasses needed.
Name/Birthday Facts:
Kusuri is a play on the Japanese word for medicine (薬), and her surname Yakuzen literally means "medicinal cooking" (薬膳). Her birthday, April 18th, was designated Invention Day in Japan to honor the country's first major patent law from 1885.
