Yi Sang

Official description
Formerly the youngest chief researcher at the [REDACTED] Wing, this Sinner possesses higher intelligence compared to most others. We estimate that everyday conversation with this Sinner will prove difficult for managers selected by our current screening process. Avoiding communication altogether will pose a risk on its own, however. If the Sinner remains silent for a long time, that means he is currently processing a line of deliberate thought; we recommend waiting patiently for him.
