Marked

"You are underestimating me!" The demoness shouted as her skin around her neck hardened. 

However,

Slash!

The sword ignored her defenses and slashed through neck like a knife through butter, causing the demoness' eyes to widen in shock.

Crack!

Right when he cleaved through her neck, he heard a faint cracking sound which made him frown. Looking down, he saw a broken crystal bead in her head and when he looked at the demoness neck flying through the air, he could see a sneer at the corner of her lips.

Swoosh!

Suddenly, the broken parts of the bead diffused into a strange energy which then entered his body and a black 'Kill' mark appeared on his forehead.

"What the fuck is this?" He muttered, touching the mark. Although the mark didn't affect him negatively, he could feel it would bring him a lot of trouble.
