YUHI
Fear was a great motivator.
For Terashima Yuhi, his fear was the thought of closing his eyes and falling asleep. Sleep was the last thing on his mind at the end of the day.
The enveloping darkness only brought him the anxiety of what's to come: the haunting memories that constantly plagued his subconscious, trapping him within the confines of his guilt and the devastating fact that he had failed his duty and failed to protect his friend.
After countless nights of abrupt slumber, Yuhi learned that guilt was a double-edged sword. While it kept his mind on track to find his friend's killer, it also deprived him of rest.
