3rd person POV:

Inside the temple is where Adam is currently at but suddenly mysterious eyes of different colors appears in the shadows as the only light in the room is from the ceiling aiming in the center at Adam who is looking at the shadows with curious. However one voice spoke that caught Adam and every other eyes attention "so you're the one that we gonna teach huh?" A male voice spoke as the mysterious male blue with hint of red stare at Adam.

Adam chuckle a little before making a serious face "yeah after all I think it high time everyone to start see the light" Adam said in a tone of liberalization. Many of the eyes look at each other before revealing themselves as characters that either don't give a damn or as a primary rival however only a few can be recognized. At that moment Adam know his moment to free the world from corruption and liberty it from those who are bastards will change forever.

An: I sorta got stuck with who else I can add so please comment if you know anyone who can teach Adam.

But out of them all is who help Adam the most as this man goes by multiple names however to those he teaches and those he calls friends call him Sage and thanks to him what be 3 years in the temple turns out to be 3 months outside.

However there is one thing about Sage that make people question him. He is the most least pervert man throughout the Multiverse for you see Sage once spot a woman from a orb and let just say he became a perv for ten seconds before he stop. Sage explains that sometimes he became a perv when he spot a woman but after a few seconds he stop being a perv since he is a gentleman yet he have a split second personality of a perv. Anyway once Sage is no longer a perv he is a great teacher to Adam as Sage teaches about everything involving the Multiverse itself.

But within 3 years inside the temple Adam became a powerful and skill man however once his training is done he decided to stay away from Union Academy and the city the Academy is located at. Which leads Adam to ask his teachers if they knew a place he can stay before returning to the city. Dante suggests going to the Netherworld Academy since it can help Adam with the mastery at that academy. And so Adam pack everything he have including gifts from his teachers before leaving the temple making Adam seventeen again once he step outside and begin his journey to the Netherworld which is located at the City of Hell. Along the way he met a few beings who help him train on his way but every time he success his training they left however they did gave him gifts before they left.

After three months of traveling he finally reach the Netherworld Academy where he had accepted by the headmaster Radek.

And so Adam learn and study in the Netherworld Academy for three months with demon and succubus teachers who is impress with Adam knowledge and determination which earn their respect along with a few students minus a couple students. However after three months Adam has be able to master everything the Academy have to offer which is surprising a lot but before the final day of the Academy, a tournament will begin in the Pain coliseum.

Adam decide to take part as he want to fight however once every contestants is gather the announcer spoke "Hello everyone! As you all know the tournaments is a every six months deal but this tournament is special as the victor will have the honor to marry the princess of Hell!" He said.

Adam thought it was a spoil girl since he know that most royals are corrupt but boy was he wrong as the princess of Hell is a young woman with three roses in her red hair reveal herself on a platform meant for royals. Beside her is a woman with white hair as the announcer spoke again "welcome Princess of Hell Kritanta and her mother queen of Hell Sophie!" He said before he became frightened along with everyone minus Adam and the two royal family members at a sinister aura.

Walking out from the darkness of the platform is a huge demon lord who is releasing an aura throughout the coliseum.

The demon lord then spoke in a loud tone that can out beat the announcer "listen well contestants only one of you can be worthy of our daughter hand in marriage so be warn if you are the victor" he said before the three royal family members took their sit. Once everyone settles the Announcer spoke but stutter a little "as you all can see our king Gifflet is here too so good luck contestants!" He said.

Then the entire tournament became a battle royale with all the contestants making everyone minus the royal family to roar and cheer at the battles between the contestants. After a hour nearly every contestant is down but only two remains and that would be Adam and John 'ace' (name from Stephen king) who is holding a knife in his left while his right hand/arm is a steel blade (from terminator) as the two face off.

John then dash and try to attack Adam but he just simply vanish surprising John who is immediately got punch in the face by Adam and slam into the ground however he got up and stare at Adam with hatred. John try and try again but it result the same however John decided to make Adam angry by using insults "all you do is vanish and punch like a f#cking coward who is a disappointment! I bet your parents don't love you" John said with a smirk.

Many demons and even royal family glare at him however to everyone shock Adam suddenly unleash an aura of pure evil making John sh#t himself. Adam turn his head to glare at John who is completely frightened at Adam death glare while Gifflet is smiling "well I be damn he gonna be the new beginning for everyone" he thought.

Gifflet then turn to face his wife who smile at him but once they turn to face their daughter they are completely speechless at Kritanta panting like she is in heat while having hearts in her eyes however after a few seconds Gifflet chuckle a little while Sophie giggle softly. "Guess we found our daughter special one" Sophie whisper to Gifflet who nod "indeed but she is much more kinky then you dear when we met" he said making Sophie blush slightly. She then playfully smack Gifflet arm before the two turn to see how this will play out for the scared contestant.

Back to Adam who is standing over John who is on the ground shaking in fear but after what felt like hours for everyone it turns out to be a second as Adam grab John head and lift him up before ripping John spine right off his back. Then Adam use John own spine to shove it right up his butt before ripping John in half along with his spine making everyone completely speechless but after a second they cheer for Adam.

Two hours later and walking towards the castle:

After the tournament ends Adam calm down and start to walk towards the throne room where he enter and saw the royal family on the thrones however once Adam and Kritanta eyes met they both blush. Gifflet and Sophie both smirk at each other as they had a similar thought "grandchildren" they said in their minds then Gifflet cough making Adam and Kritanta to immediately stop blushing.

"Now tell us young one your name since we didn't caught your name when we return to the castle" Gifflet said making Adam took a breath in and out before answering "I am Adam, Sir" he said. "Now then Adam tell us once you married our daughter what is your plan" Gifflet said staring at Adam "well i want to get to know her before the wedding so with your two blessings and her permission to travel with me" he said.

Kritanta eyes sparkle with excitement while Gifflet and Sophie stare at each other and smile before they answer yes making Kritanta to blast and hug Adam immediately as she kiss him making the two parents to laugh/giggle at Kritanta excitement. Adam return the kiss before they stop and got up as Adam have one thought in his mind "this is gonna be a hell of a time" he thought with a smile.
