Summary
Yakuzen Kusuri is an eighteen-year-old Aries born on April 18th, which coincides with Invention Day in Japan, a date established in 1954 to honor the nation's first major patent law from 1885. Her name carries significant meaning, as Yakuzen translates to medicinal cooking, while Kusuri serves as a homophone for medicine or drugs. She attends Ohananomitsu High School as a third-year student in Class 3-3, where she serves as the President of the Chemistry Club and holds the distinction of being Aijou Rentarou's fifth girlfriend. Kusuri is characterized by her energetic and ingenuitive nature, often concluding her sentences with the suffix "-nanoda." Her passion lies in the creation and consumption of various drugs, which she utilizes in nearly every situation. Despite her capability to formulate a remedy for almost any issue, she frequently fails to recognize the potential dangers or consequences involved. She is largely unconcerned with safety, happily forcing her creations onto others as test subjects or consuming them herself without hesitation. Physically, Kusuri appears as a slender teenage girl with turquoise eyes and long, wavy red hair tied in a ponytail. She wears glasses and features a beauty mark on the left side of her bust. However, much of her time is spent in the body of an eight-year-old child due to the effects of an immortality drug she consumed. In this younger form, her hair is shorter, she no longer requires glasses, and her overall stature is significantly smaller.
