Character Sheet
Einar Sirius du Lac (MC): Chapter 2
The first name is Einar, Last name is Sirius, and additional title due to son of lady of the lake.
He was a cancer patient in a past life then reborn in Arthurian Legend of Nasuverse with the weapon Chastiefol. Chastiefol is not a weapon but a book where he could unlock new forms of Chastiefol by writing his experience in the book. This gives him purpose to discover the outside world and not make him shut-in.
About him, he is born as half fay, and since Fay/ fairies grow slower, he will age much slower that makes him concern about his height like Edward Elric but he will grow in the future so don't worry.
He also has a quality of mana much bigger than even Merlin's. He is a mage at core and spearman at side job for direct combat.
H desires to stand beside and up for King Arthur.
He is an easy-to-go boy unless you mock his height or Artoria.
Vivian: Chapter 3
She is known as the lady of the lake and foster mother of Einar. She loves her son and sometimes becomes overprotective but since she loves him, she can't always protect him so to make him stronger, she lets him out with Merlin for his further growth, hoping to help the fateful one in dire times.
Merlin: Chapter 6
Best mage in Britain and is/will be the advisor of King Arthur. He is generally good and understands people but he can't truly sympathize with them. His character will further be explained. He is also the teacher of Einar who he dotes.
"Hey not fair! I am a big shot in this story! Explain my grace in detail!"
Don't talk Merlin. Sorry for breaking 4th wall.
Kay: Chapter 7
Son of Ector and foster brother of both Einar and Artoria. His relationship with Einar is that of love and rivalry between true brothers. He is someone who understands everyone the most but he is a knight and has little authority as most of the matters are already decided by Merlin and Uther to which he doesn't like just like Einar so they will get along.
He uses his lance as a weapon. He also has the longest tongue behind Einar that he uses against Artoria and wins against her.
Ector: Chapter 12
Father of Kay and Foster father of Artoria. He would train Einar as a knight. He is also the most trusted vessel of King Uther and mentor for Kay, Einar, and Artoria.
Maria (OC): Chapter 12
Lady of the house of Ector.
Artoria Pendragon: Chapter 11
Also known as Arthur Pendragon to the outside world, is a girl but living as a boy as far as she knows. Everything for her is already been decided by Merlin and Uther from her birth so she could only move forward for that purpose of 'an ideal king.' She doesn't know how to react if someone (Einar) treats her like a girl that leads her to blame herself.
She is an airhead, sore loser but hate to lose. She is stubborn and sometimes acts on impulse whatever she deemed right for the rightful for 'greater good.
Everything was grey until Einar.
She will wield three weapons in her lifetime.
Caliburn- Weapon prepared by Merlin for the 'rightful king'. Artoria would eventually lose it before the conquest of Camelot.
Excalibur and Avalon- Artoira's main weapon that she will use to gain victory over victories.
Rhongomyniad- A lance contains immense power but its original power is that of tower of light that could destroy anything with 'darkness' and the lance is mere shadow. Artoria would use it to kill Vortigern, evil demon dragon, or white dragon.
