It's been fourteen years since Jack had been transmigrated to the world of Black Clover. The best way to describe how he looks is by looking at Jack Frost from Rise of the Guardians but with Ryan Reynolds' face and more muscles. What people can see him wearing is a cobalt blue hoodie, black trouser pants, and no shoes. He feels better without them.
He has snow white hair with streaks of sky blue. Snow white eyebrows. His eyes are electric blue.
Jack's personality is very mischievous. He's a real people's person unless angered. He loves bringing joy and humor to anyone. Jack also likes pulling pranks on everyone. A real Trickster. He helps out his entire village since they've taken care of him.
Anyways, Jack, Asta, and Yuno are standing in the grimoire tower awaiting their grimoires. He can tell he's not the only one excited. With Yuno it's hard to tell since he controls his emotions. But for Asta you can tell because he's hopping from one foot to the other with a large ass smile on his face.
(I'm not gonna explain what those two look like because they aren't my MC. Just look online and you'll see them.)
Jack just has his hands in his pockets looking up at all the grimoires. Wondering which one is his. He's been waiting for this moment ever since arriving in this world. He trusts God more than anyone. So he knew that the being he saw as his only parent wouldn't let him down. If God says he will do something, he does it. Ever since Jack had seen God he became an official believer in the Creator.
Jack knew God came through with his wishes because 1. He didn't doubt the man upstairs and 2. Because when he awoke his powers he froze the demon skull completely. He had a much better grip on them now. Could still use some more practice though. That's where the pranks come in handy!
Finally the Grimoire Tower master came out of his office. He stood up at the top of the stairs to his office looking down at the gathered fifteen year olds. He gave them a grandfatherly smile.
"Welcome young mages to the start of your long journey to become powerful mages in the future. Today you will be getting your grimoires. Before we start I would like to say two things. Number one, Jack please unfreeze my toilet paper. I had to use my favorite socks to…well, you know."
The children started laughing at that. Leaning on each other or completely falling over from laughing so hard. Jack just started looking around whistling innocently as if he weren't listening or caught guilty.
"Number two, (here people laughed) you can't choose your grimoire. Your grimoire chooses you. With that being said, accept your grimoires." As soon as the master of the tower finished speaking the grimoires started descending the shelves.
Some of the young mages started complaining or comparing the grimoires. Saying things like "Is this really my grimoire" or some things that other people would wonder what the hell parents are saying in front of their children.
When Yuno's came, silence entered the tower. A leafy green light started to descend from the top of the tower until it hovered in front of Yuno. When the light dimmed away there was a four leaf clover grimoire in front of him.
Almost everyone in the tower was shocked, mainly the nobles. In their minds they thought this should be impossible. How could someone with no last name and a low-life commoner get a four leaf clover grimoire. One of the arrogant nobles was about to complain out loud when something else happened.
After Yuno tucked his grimoire away another light shined. But with it the atmosphere inside the tower started getting cold, like winter had come early. Everyone could see their breath.
When the light faded away another grimoire descended from the top shelves of the tower. This one was blizzard blue. It was seven inches thick, 9 inches wide, and 12 inches long.
What made the crowd frozen in place was the very clear four leaf clover in the center of the front of the book and the single snowflake on the back.
Nobody needed to guess who this grimoire belonged to.
Jack Frost.
Once the grimoire was in front of him Jack grabbed it and held the book like he was finally whole.
Jack said a grateful prayer to God for coming through with his wish and cried a little. Tears of happiness and joy came from his eyes. Once they started falling to the floor they became snowflakes.
Even the arrogant nobles didn't dare insult Jack Frost. Because everyone knew Jack was worthy of a four leaf.
Once he was done crying the atmosphere became warm again.
