Aguri Yukimura was Class 3-E's former teacher and the older sister of Akari Yukimura, who has since passed away.
She's best known for being an enthusiastic and sharp-minded educator who genuinely cared about her students. Though chemistry was her main subject, she could teach pretty much anything—fans often note her versatility as an instructor. What really stood out about Aguri, though, was her bizarre fashion sense, which tended to confuse everyone around her. Despite the odd clothing choices, her cheerful and straightforward personality made her a memorable teacher.
