The Training Begins

 Marco was currently setting up a bonfire to cook the meat they hunted. The two monsters were happily cooking and roasting their spoils like children.

 One was cooking with great attention to detail while the other was creating a pool of drool. Although both their attitudes were different the same glint in their eyes were present.

 The glint of mutual victory, just before the concluded their little 'contest' they did something that shocked Thanatos.

 They practically shook hands? Or paws? Whatever it was they shook deciding that they both won. 

 In some strange manner a friendship began to form between the two.

 As a hog that was around 30 meters was slowly being roasted with the. Legs of several sphinx, the two were clearly enjoying the cookout.

 "Marco I think it's time we started training." Thanatos spoke seriously, he was honest shocked with the amount of power Marco displayed.

 If he were to put things into perspective, that causal swing of Marco's was equivalent to Zeus going all out.

 Thinking about the situation he needed Marco to control his power as soon as possible. Though he did enjoy the mans antics he didn't want to see the underworld blown up.

 There was a line to everything and Thanatos was at the edge of this monster known as Marco.

 "Sure, but how about a meal first? Cerberus here seems really excited." 

 Marco looked at his new friend who had its eyes shining with hunger and tail wagging causing a localised desert storm.

 Thanatos only looked at Marco speechlessly before sighing. He knew that the maniacs were lacking common sense.

 One attacked Hades and almost got killed while the other... well was a monster. He face palmed before sitting down asking for a sphinx leg.

 Marco happily passed Thanatos one of the few cooked legs before he took a bite. 

 "Oh yea, I forgot to ask but how are you going to eat the Miasma from these beasts...?"

 Before Thanatos could finished his question he saw the pale face of Marco while clutching his throat in agony.

 Thanatos looked lifelessly at Marco before sighing for the eleventeenth time. 

 "Well I guess suffering a little to get some resistance against Miasma isn't a bad thing." All while thinking "Welp the let's start the training shall we" while casually eating his sphinx leg.
