What in the world

The Seven deadly sins sat on the boar hat roof, the Ten Commandments had been revived and non of the sins were strong enough to beat any except Escanor. "I wish I had learnt both types of Full Counter." Meliodas stated looking at his comrades. "Don't we all want something Captain, like I guess you could use a power up King is stronger than you now." Ban teased.
The third fairy king had been thinking about how he and Diane had been trained by the one the giants saw as a god: Drole and the first fairy king: Gloxinnia his girlfriend Diane sat across from him shrunken to human size. Suddenly a hole appeared right above the boar'd hat and out came some odd people.
As they approached the big green pig they saw the people on the roof of the building draw weapons. " They might attack. said the young male with the two coloured eyes and white hair. The group landed on the roof and put their hands up like they were going to surrender.
Meliodas didn't like these figures they were hooded but he could see their eyes and one looked aggressive. Meliodas pulled Lostvayne and got ready to attack "get off my bar right now or I'll send you flying." He said slightly mad the smallest of the group of hooded figures stepped forward and unsheathed a black sword with silver rims and a big scratch running the length of the blade and  a shirt scratch going through the middle of that. As Meliodas jumped forward he slashed downward but the figure twirled sword above his head and hand over hand brought it down sending Lostvayne under the table and knocking Meliodas flying. Escanor got up grabbed Rhitta before allowing Gother to use his mind magic on him allowing him to transform to his buff form, Escanor charged the hooded man and swung Rhitta "Take my divine fury." Escanor said, the figure lunged hitting Escanor in the stomach before crying out "Physical Full Counter." And shooting the attack Escanor had used back at him. Everyone was shocked Full Counter was Meliodas and Estarrosa's move how did this person know it. " Allow me to explain." the figure said removing his hood to show a green eye and a blue eye and white hair that looked similar to that of Meliodas's "I'm Tristan, I'm the child of Meliodas and Elizabeth in the future after this is all over, don't worry this won't alter the future as their are many time lines and knowing my future will alter your future." Tristan said "that's how I learnt Full Counter dad taught me but I used my intuition to learn how to counter both physical and magic attacks by altering what muscles I move when countering the blows." No one believed him till the second person pulled their hood off, a young girl with flowing long white hair and crimson eyes was staring at them, she took her cloak and underneath were small bright red wings the same size as Harlequin's. " I'm Marista, I'm Ban and  Elaine's daughter from the future and this is my brother Enisho." She said gesturing to the tallest hooded figure who pulled off his hood to reveal honey gold eyes and short blonde hair, Enisho waved sheepishly and pointed at the last two figures "and those are our twin cousins Drole Minor and Gloxinnia Major names after the people who taught their parents Harlequin and Diane how to be good rulers." Enisho said. Gloxinnia Major looked like a mini Harlequin from the wings to face the only difference was the dark brown hair and purple eyes while Drole Minor looked like a small Diane with Harlequin's hair and eyes.
No one could believe that they could see their children this close at this age but Ban was less sure than the rest "How about a little test to see if you are my children." He walked up to Enisho and using his steak knife stabbed him in the heart, Enisho started laughing his head off and before long the blade was also in Marista's throat "Nice work pops." The siblings said looking at their father and before long Ban was more convinced than any of the other crew mates.
