Kusuri Yakuzen

Yakuzen Kusuri is a third year student at Ohananomitsu High School in Class 3-3, the President of the Chemistry Club, and Aijou Rentarou's fifth girlfriend. She loves to make drugs, always making them or using them in almost any situation; however, she tends not to realize the possible danger or consequences that these can have. In her normal teenage form, Kusuri has turquoise eyes and long, wavy red hair she keeps in a ponytail. She wears glasses, has a slender build, a large bust, and a beauty mark on the left side of her bust. However, due to a having consumed a drug that was supposed to make her immortal, she spends much of her time in an eight-year-old body. In this form, her body is smaller, her hair is shorter, and she does not need her glasses. Kusuri is energetic and ingenuitive. She is capable of creating a drug for almost anything. She doesn't tend to be concerned about the dangers of the drugs she makes and will often happily force them upon others as guinea pig or take them herself without hesitation. Most of the time she ends her sentences with "-nanoda" ("yep, yep" in the official translation and dub), just like her family does although they do it with other words.
