Name: Yunde Hoshibami Age: 25 Affiliation: NEST Rank 50 "Night Owl" Role: Recorder Skilled with knives. Yunde's twin brother and Guest's older brother. Personality: Capricious and works at his own pace. He hides a cold-blooded and combative side. A mean-spirited, free-spirited genius who appears out of nowhere and vanishes before you notice. Provoking others is a daily occurrence for him. Like his brother Mete, he lacks any sense of justice or ethics. If anything, his personality is even more deranged than his brother's. Past: Same as his brother. One difference is that he once genuinely tried to kill someone who harmed the Night Owl detective, "Chito Sumeragi." He has been under NEST surveillance ever since.
