Richard's transparent glasses were special, as they were a program that could hack the camera and let him know about Anxia's exact position. This program could also make him see in the dark and tell him that an enemy is behind him. You could say his glasses were a third eye to see Richard's blind spot.
The first time he arrived at the balcony of Anxia's room, he saw someone he didn't know sneak in and was about to set up a bug. Richard approached the person without a sound, hit the intruder's nape, and immediately caught his limp body soundlessly.
He could tell this person's identity through his glasses, and it turned out that this person was one of the people working in this place.
Why would this person's superior send someone to sneak into his guest room?
He thought Anxia would be held in the most minor place, like the detention room. But Anxia was treated as a guest here, so he didn't need to add a list of prey to be punished.
