It happened on the day they killed the Carapace Demon. Back then, all three of them were utterly exhausted. After moving away from the corpse of the giant creature and finding a good hiding spot, they fell to the ground and immediately fell asleep.
But they didn't stay asleep for long.
An hour or two later, Sunny was shaken awake by Cassie, who was holding him by the shoulders. There was an expression of terror written clearly on her face.
"Sunny! Sunny! Wake up!"
Instantly coming back to his senses, he jumped to his feet and summoned the Midnight Shard, afraid that they were under attack.
However, there was no one around except for panicked Cassie and wary Nephis, who was in a similar pose, her sword raised and ready to strike.
Confused, Sunny looked at the blind girl.
"Cassie? What's the matter?"
Grabbing him by the shoulders again, she brought her face close and whispered in a begging tone:
"Sunny, you have to stop it! Please! You are the only one who can!"
