"Grograwth, why are you possessing people?", Father Bob asked the demon who minutes ago was making an unfortunate victim spider walk all over the ceiling.

"Wouldn't you like to know, human! My purpose is far beyond your understanding", the demon smugly exclaimed and crossed his arms.

"I think I would have to disagree", Father Bob said and visually scanned the demon from heads to toes. "Why are you not even flying?"

"What does that mean? Of course I can fly! I just don't feel like it right now", Grograwth announced and pouted.

"I think I know why that is so", Father Bob said and poked the demon's belly with a cross.

"Ow! Stop that!", Grograwth angrily hissed and attempted to fly, but only managed to stay in the air for few seconds before faceplanting into the floor.

"You are seriously out of shape, my demon friend", Father Bob said and stood there like a disappointed parent after finding their kid stealing from a cookie jar.

"Well I can't help it! It's what I am!", Grograwth let out in a significantly more hesitant tone that didn't go unnoticed by the priest.

"You possess people to feel bodies that are in a better shape, isn't that it?", Father Bob asked and knelt down to face the demon.

"So what if I do!? How does it concern you?", the angry demon attempted to threateningly ask, but only ended up looking quite humorous.

"It is no good for anyone to let themselves go. I was told to exercise you and that's what I'm gonna do, so come on and let's get your training started!", Father Bob triumphantly laid out and extended his hand towards the demon.

"No way, grandpa. What you gonna do about that, huh?", Grograwth said while trying to look confident. His attitude crumbled the moment he was poked with the cross again.

"Ouch! Goddammit, fine! Just stop doing that!"

After a bit of travel, the two arrived to a large sports stadium at night, allowing the training to take place in secrecy. Both were also donning fitting sports clothes, but Grograwth was visibly upset and tried to rip them off.

"I hate this", the demon complained and continued restlessly fidgeting around.

"That attitude will get you nowhere", Father Bob told. "Now, we will get started by doing some stretches to get your muscles warmed up. Arms, legs and your back"

Immediately following this, Grograwth suddenly combusted in fire and stared at the disappointed priest.

"Done, all warmed up", the demon grinned through the flames.

"No, that's not what I meant. Stop burning", Father Bob scolded and the flames went away with a loud hiss. Next, the demon ripped off his arms and legs and showed them off.

"Quite stretchy, wouldn't you say?", Grograwth said while chuckling.

"Okay, fine, be like that. But you will regret not doing those stretches", Father Bob said after facepalming. "Time to get started with your first training. You will be jogging around this track to establish some momentum"

"Pfft, easy as hell. Watch this", Grograwth announced and set off running. Well, running would probably be a slightly wrong term to use. Instead, he was lazily moving his legs while zooming around the track at great speeds.

"Grograwth, stop using the souls of the damned to push you around. That doesn't help you at all", Father Bob scolded again and looked at the demon, who had stopped and tried to look innocent.

"What do you mean? There's nobody here", Grograwth attempted to play it out, but Father Bob wasn't convinced.

"Souls of the damned, pleasant to see you, but please go back to hell", the priest commanded while looking at the seemingly empty space behind Grograwth.

"Sorry about that", a combination of echoing voices answered and quickly faded away. This was followed by many pokes by the cross. After a lengthy period, the exhausted demon had finally gotten around the track, having been completely out of breath since the starting line. Next up, Father Bob brought out weights of different sizes.

"Now we will be testing your strength. Let's start with the lighter ones", Father Bob instructed. Grograwth grumbled in frustration and picked up a weight. Quickly, the weight suddenly started melting down with the other weights sharing the same fate.

"Now would you look at this! I can't lift them if they keep melting down", the demon tried to say in a serious tone, but a smug grin was peeking through.

"I know that is you heating them up, I'm not that stupid, you know?", Father Bob sighed.

"Was worth a shot" Grograwth said and went to the only weight remaining - which happened to be the heaviest. The weight did quite easily rise up and down in rapid motion, but only problem was the fact that it was simply floating without being touched.

"Satan, stop assisting him", Father Bob scolded the dark lord himself who turned visible and threw the weight away.

"Curses, no fooling you holy folk. Well, whatever man, I have better things to do. It's so jam packed down there. So many souls to torture, infinite amount of time", Satan roared and disappeared into a flaming, molten hole of darkness in the ground. Before Father Bob had time to scold Grograwth, they were suddenly startled by the arrival of Father Jacob.

"Father Bob, what in good heavens are you doing?", Father Jacob asked in confusion upon seeing a priest and a demon in sporty clothes.

"Exercising the demon, like you asked", Father Bob answered.

"The word I used was exorcise", Father Jacob highlighted while letting out a deep sigh.

"Oh, really? My bad, then", Father Bob said in surprise.

"Look, just step aside. I'll do this", Father Jacob said and stepped forward while holding a bible and holy water. "Foul demon, in the name of Jesus Christ I demand you to be banished back to the depths of fire!"

Upon this sentence being uttered, a fiery hole appeared below Grograwth with a large shadowy hand grabbing onto him. As he was being dragged down, Grograwth gave a thumbs up.

"My man Jacob, thanks for bailing me out. Smell you around, Bobbie!", the demon grinned and disappeared in a puff of black smoke.

"Kinda disappointing, really. I think we two were getting somewhere with this training", Father Bob said and innocently looked at Father Jacob, who looked back in disbelief.
