Ibaragi Yoshimi is one of the students studying in Trinity General School. She is the head of the After-School Sweets Club. She has a complex about her height and physique, and always gives the impression of an angry small animal. Yoshimi from the After School Sweets Club! It seems that she has been appointed as the guitarist of the hastily formed band "Sugar Rush"! Yoshimi apparently created the band's icons, symbols, costumes, and other visual aspects!
