Betrayal

Kaisen raised his eyes at the item description of the masks in his hands. It was as if the universe had handed him a Swiss Army knife in the form of a mask.

[Mask of the Mischievous]

[Class: Rare]

[Description: A mask said to be crafted by the legendary blacksmith Grover, granting its wielder the ability to temporarily transform into another person.]

[Requirement: DNA of the target.]

He smirked, imagining all the hijinks he could get up to with such a mask. It was like being given a backstage pass to every masquerade ball ever held.

All he needed was a sample of his target's DNA and he could become anyone. 

'Night Shades must've taken Alice's and the others' DNA at night. That's why they prowled around at night.'

He recalled seeing pairs of red eyes outside the cave. At the time, it had been like spotting glowing cherries in the dark—terrifying.
