Gawain
One of the Knights of the Round Table from Arthurian legends.
One of the longest-serving knights, a devoted knight who served until the conclusion of the king's fight.
Possessing the holy sword of the sun, said to be Excalibur's sister-sword, he won fame as a peerless knight who was unmatched during daytime thanks to the blessings of a saint.
A prince charming with a gentle smile to match.
Despite his serious character, he has no gloomy aspects and interacts with anyone in a sincere and polite fashion.
While he may get enraged, since he never harbors negative emotions such as jealousy and malice, his attitude is refreshing no matter what kind of battlefield.
According to the other Knights of the Round Table: "That lack of sarcasm is already a talent".
For Gawain to have never been envied, despite blessed with talent and pedigree, was probably due his own good character and the natural airheadness to think of it as a matter of course, without ever being boastful.
A loyal knight, his faithfulness to the king was like iron.
Gawain himself wishes for nothing but to be a single sword for the king's sake.
...to a third party that does not know of his inner aspects, such a sorry state might even seem like blind devotion.
Although he has many brothers in the round table, he says that he was particularly friendly with his sister Gareth.
It is the greatest regret for him that his anger led to the plight of King Arthur, furiously raging at Lancelot who murderously slashed Gareth. Agravain handed over to Morgan by childhood, and Mordred, a brother-in-law, greeted their last fight with each other unfamiliar.
