Jin works behind the scenes as part of ES operations, mostly handling support duties for the idols. He's got a reputation for finding excuses to pass work off on people, but he's genuinely thoughtful with the younger staff and students—he's just got that gruff exterior. There's definitely a serious side to him underneath the easygoing attitude.
He teaches at Yumenosaki Academy while also working as a sports doctor, keeping tabs on how the students are physically doing. As a former idol himself—and a pretty successful one at that—he brings real credibility when he advises the current generation. Being an alumnus gives him perspective most staff members don't have.
