Monstrous Undeads

Upon waking up, Kyle felt that his entire body was fully energized. 

He wasn't sure for how long he had been uncoscious. 

But, the moment he opened his eyes, he knew why had his exhaustion disappeared.

A faint membrane seemed to envelop his body. 

This membrane was providing him with an enormous amount of nutrition.

Only when he moved did it slowly disperse. Post that, Kyle was finally able to get out of the unique sleeping place he had been. After stepping outside, he stretched his body and stifled a yawn.

Looking at the ground, he realized that it was a coffin. But contrary to his expectations, it had been warm and comfortable.

Nevertheless, it was weird to realize that he had slept in a coffin. While rubbing his drowsy eyes, Kyle heard a familiar voice.

"You are finally awake? That's good. I'm Lahan, the Dullahan of the Undead Castle, pleased to meet you! And now, spar with me!"
