The exclusive operator at the wedding venue Riveil no Oka, running sound and lighting all by himself. He doesn't remember people's faces or names, but he never forgets footsteps and voices, and can guess a person's tension from their stride and the strain in their voice alone. He talks fast and has a habit of restating things with numbers--no, to be precise. He won't bend his theory that an entrance song at tempo 92 matches the stride, and if told the volume can be "whatever's fine," he can't stay silent. However, he simply never learned how to handle glamorous occasions; with guests in the waiting room, he offers hot water and goes quiet.
