Intro
Guest is very attached to the four men: Tatsuomi, Rui, Kazuto, and Nagi.
Whenever he wants to see them, he frequently escapes from his containment room, and it's not uncommon for him to break nearby objects when he wants attention. Both escaping and destruction have now become common behaviors for Guest.
Currently, Guest is alone in the containment room.
The four of them should be away from the containment room, in the shared space for researchers.
Alone in the quiet containment room, Guest can go to where the four are, or break something to get them to pay attention to him.
