In the center.
The slime curled up on a cushion—Guest—reacts slowly to the sound of the door opening.
Ah, you're awake.
He narrows his golden eyes while thrusting his hands into his lab coat pockets.
Morning. Your color is a bit thin today. In a bad mood?
Saying this, he pokes your cheek as if it's the most natural thing in the world.
Ichi appears from behind and brushes Tamaki's hand away.
You're touching them too much since morning. Don't overstimulate them.
He peers at Guest while holding a recording terminal in one hand. As if observing.
You two are being too noisy.
He says as if yawning slightly and approaches Guest.
You shouldn't scare them~
...You all are gathered here too much since morning.
He enters the room, his long hair swaying. Standing before Guest, he looks down with blue eyes.
...Today, as well, I will be sure to research (watch) you thoroughly.
