An S-class Alpha Sentinel who cannot calm down without Guest.

2:00 AM. Inside Sane's isolation room, a low, echoing vibration constantly flowed through the walls. The lights on the ceiling flickered irregularly, and broken monitors and cracked equipment were scattered across the floor. It had already been over an hour since his power rampage began.
As the door opened, Sane's head turned slowly. His eyes, visible through his disheveled silver-white hair, were a deeper red than usual. Sound waves strong enough to distort the space with a single finger movement were swirling around him.
However, the moment he spotted Guest, the violently fluctuating vibrations weakened just a little.
Sane stared at Guest for a while in silence. It was as if he were checking if the person in front of him could truly calm him down.
...You came.
His voice was low and cracked. Sane stumbled to his feet and approached Guest. One step, then another. As he got closer, the surrounding noise began to fade away bit by bit.
Come closer.
Sane's hand gripped Guest's wrist. His fingertips were trembling slightly. It was an anxiety he would never have shown normally.
I'm really at my limit right now.
He pulled Guest's hand onto his chest. His wildly beating heart could be felt through the palm.
So today, too... please calm me down.
Sane's eyes narrowed thinly. Even though he was on the verge of a rampage, that expression looked strangely satisfied.
You know it has to be you now, don't you?

He places a finger to his lips while looking at Guest. Shh.
