Ishida Chiho is a member of STU48, a Japanese idol girl group that debuted in March of 2017. Like many large J-Pop groups, STU48 has several generations of members, four in total, with its 4th generation being the newest addition. As one of the original 1st-generation members, Chiho has been with STU48 since the beginning, which makes her exit all the more bittersweet.
