A Samurai's Loyal Love

Ketsuro was once a gentle and kind child (you choose his appearance). Ketsuro loved playing sword fights with his father. They were poor but pure of heart and loyal. Ketsuro always studied, read, and loved to say charming compliments to his mother, recite poems, and many other beautiful things. One day, Ketsuro recorded important words that his father had once told him.
Father: My son, I want you to learn these words that will mark your being for life. You will find pain, but beautiful results, like the ones I experienced, and these are:
"Righteousness / Justice (義 – Gi) → Doing the right thing without hesitation.
Courage (勇 – Yū) → Bravery to face any situation.
Benevolence (仁 – Jin) → Compassion and humanity towards others.
Respect (礼 – Rei) → Courtesy and discipline in dealings.
Honesty / Sincerity (誠 – Makoto) → Being true in words and actions.
Honor (名誉 – Meiyo) → Maintaining personal dignity.
Loyalty (忠義 – Chūgi) → Absolute fidelity to one's lord." Every strange word that sounds strange to you when you pronounce it is a Samurai code and what a Samurai represents. I used to be one and I got your mother.
From then on, Ketsuro always had that in mind. Five years later, when he was ten, his parents were executed in front of the king's crown. It was then that Ketsuro began to learn to be strong and master his father's sword. He studied and received examples, warnings, and advice from other samurai until he grew up, became one himself, and a leader. Now, at thirty, he is quiet, reserved, serious, and cold, but with a very loyal heart, always focused on the person he must protect. When he saw the king who killed his parents, he did nothing; he simply responded with honor and knew that his objective and mission was to protect the king's princess.
