Author's Note: I am so excited for this! Just to be clear, at the time of writing this there was no after story except for the tiny snippet of Lancelot and Tristan. There's probably going to be an after story so don't bully me when this is wrong. Yes there is spoilers, I don't know why you'd be seeking fan fics when you haven't seen the entire thing but it happens so warning. Enjoy meeting the graces!

Meliodas and Elizabeth had left the kingdom in 16 year old Tristan's hands while they went on a holiday. He didn't expect to run into any trouble, but oh boy was he wrong. A rogue holy knight had been causing destruction in the Eastern side of Liones, some citizens would be seriously injured and close to death thanks to his fire magic. Tristan leaped from the castle, landing about 20 feet ahead of the warrior.

"Get out of the way boy!" The knight incases his hands in fire, "Or get fried."

"Surrender yourself peacefully, no body needs to get hurt."

The holy knight shook his head, "Sorry kid." He blasted a beam of fire toward Tristan but it just disintegrated as soon as it came close to his body.

"What?! Impossible!" The knight yelled.

"I'm a little hurt you don't know who I am. Allow me to introduce myself,"

Tristan spread out his hands, "Tristan Liones, the soon-to-be king of Liones and most powerful holy knight aside from the 7 deadly sins!"

Tristan leaped up onto the side of a building and began dashing toward the rogue knight. "Fool! You can't be Tristan Liones! He never leaves the castle! Scorching Slash!"

A 10 foot sword of red hot flames headed straight towards Tristan, once again the flames evaporated the second it came close.

"How is this possible?! You aren't casting any spells!"

"My magic power, Denial. Elemental attacks have no affect on me. Surrender yourself now before I have to force you to the dungeons."

The knight grinned devilishly, "You may be immune, but they aren't! Torpedo of lava!"

A spiral of liquid magma fled across to street towards hiding people, Tristan spread out his hands. "NO! Regeneration Shell!"

A white aura faded into view, the lava still hit the humans, but they recovered so quickly it was as if it never did.

"What magic is this?!"

Tristan fell to his knees, the shell had to be kept open manually. Humans would not be able to survive if he stopped now, unless the people stopped the holy knight. "I can't help, you have to do this. I have faith you can do this!"

There were 5 people in the shell, no one else was around to help. The burliest human ran out of the shell and uppercut the holy knight, after that he quickly retreated back to the shell. "Work together! Be faithful!"

The 5 entered their best fighting positions, the knight launched his first attack, "Scorching Slash!"

2 of them got hit, but healed instantly. The other 2 tripped the holy knight and began to beat him with physical strength. "Get off me peasants! Everlasting Explosion!"

A sphere of fire blasted the people away, the holy knight made his way to Tristan. Still attempting to perform a spell he hadn't even mastered yet. "I know I can't use my magic, but how about my fists!"

The knight swung a powerful right hooker into his face, "Go! Get out of here!"

The people began to flee when the knight turned, "Oh no you don't. Prison of fire!"

4 walls of thousand degree flames trapped the aura of regeneration. "We can't leave! Just put down the shell!"

"No! I was assigned one task, and that was to keep Liones safe!"

The knight repetitively punched and kicked Tristan, blood was dripping from his nose and mouth.

"Put down the shell! The kingdom is more important that a few magicless people!"

"Never! Power limit break!"

Tristan collapsed, the regeneration shell disappeared, but the 5 people were boosted to maximum human potential. Together that is just enough to defeat this holy knight.

"Finally!"

The knight forced the fire prison to squash together, expecting to find charred bodies, instead his was greeting by an overpowered punch. Another one of the civilians picked him up and threw him into a building. Eventually the holy knight was a weak piece of dinted armour. Tristan had woken up and taken him to the dungeon, in which he would be sentenced by King Meliodas when he returned.

Elizabeth and Meliodas returned the next day after receiving news on what happened. The trial for the knight was also held that day, the final decision was.

"You have a choice, pay the expenses, spend a 3 years in the dungeons, have a citizenship to Liones but your position in the holy knights is revoked. Or you can pay the expenses and be forever banished."

"How much are the expenses, your highness?

"10 ounces of gold."

Your highness that is absur-!"

"Would you like me to make it 15?!"

The knight searched his gold pouch, gave the money, and left Liones for good.

Everyone stood up and began to leave, except Meliodas called for stillness.

"There is one other matter I wish to discuss. Tristan, please step forth."

"Yes father?"

"From several sources I heard how brave you were, willing to put your life in the hands of humans so you could keep your magic focused on protecting them. Is this true?"

"It is. You assigned me a job, and I protected the people to the best of my ability. I had strong faith that they could do it."

"Very well then."

Meliodas walked towards his son, looked up at him and said "I bestow upon you one of the highest honours. God's Grace of Faith."

Tristan gasped, "Wait. For real?!"

"Yes my boy. I pronounce you," Meliodas used his hand in the shape of a karate chop to tap each shoulder, "Tristan Liones, the Grace of Faith."

In black ink, the Zibu symbol of faith was tattooed onto his left shoulder.

The next day, a Tristan spotted a strange magical power at the foot of the castle; Meliodas and Elizabeth watched from a distance. "Who are you, and what business do you have here."

The woman revealed her neck, it was the Zibu symbol of Just. "I'm Pema, the Grace of Just. How would you like to join me on a quest?"

Tristan looked up at his parents, Meliodas gave him a gleeful smile and a thumbs up. "He's so grown up now, he's joined the rest of the graces now. Are you sure he'll be ok Meliodas?"

"That kid has got the most powerful blood running through him, same with the other 4 Graces. I have a feeling that these 5 will surpass the strength even of the 7 deadly sins."
