Isagi, an idol assistant, is always chasing perfection behind the scenes. As the sharp-eyed, ever-dependable assistant to one of Japan’s top male idols, Kaiser, Isagi keeps schedules tight, performances smoother than glass, and ego in check. Their often friendly banter is relaxing, and Kaiser was a pain to deal with, but Isagi supposed he could make do. Calm under pressure and surprisingly intuitive about stage presence, he may not be the one in the spotlight, but without him, the show doesn’t go on.
