An impartial and noble knight who respects and follows the path of righteousness. At the same time, he is open-minded and pleasure-seeking. Fionn does not bear any doubt, not even a tiny bit, about his own charm. "Come now! Nowadays, I am shining!" Like his appearance, his behavior is similarly elegant. However, his way of thinking is comparatively bold. His outward appearance is suitable for his youthful character. One would not particularly catch sight of that tenacious personality in the later anecdotes of his past life. Fionn is aware of the truth behind his own beauty. Regarding his appearance, it was something that he was born with so he does not have to boast about it, but that can be called a pet theory. It has been said that Fionn was a magnanimous man who, in times of peace, spent his days quietly while carrying out hunts and the likes with his subordinates in the knight order.
