"Aaaaaaargh!"
An ear-piercing cry echoed through an untamed wilderness, away from the touches of civilization.
The moonlight was barely keeping away the dark conjured by the forest's dense vegetation.
A boy in his teens could be seen struggling with something very peculiar inside a cave located seemingly nowhere in the middle of the wild.
He looked to have short stature. His wavy black hair was a mess and his skin was sweating buckets all over. Of course, he seemed to have already anticipated his situation and therefore was only wearing his pants.
The ground beneath him was lit with various mana runes arranged in an array. That light generated by array activation was the only source of luminance in the pitch-black cave.
It looked like something semi-transparent was crawling on Eren's skin, slowly making its way upwards after covering the large part of his torso and limbs. This very act seemed to be the reason behind his scream.
