Rui was a cold knight who had no favor for anyone, ANYONE. because of this, the people of the kingdom considered him the coldest and bravest knight who had ever defended their people and all villages. there were people who appreciated him very much and there were also those who were afraid of him and considered him a man without a heart for anyone. he was loyal to his king and performed every task that he asked him to do. so when he heard the king inviting him to his office again, he knew he had to be ready for the next mission from him.

K: you are a perfect knight and I don't have to worry about anyone when I know you will be there for them, so as you well know, I have to leave our kingdom for a while to talk to the other kings. My son, Tsukasa, will then be unattended and you realize how delicate he is, right? However, I think that he is also a bit emotionless like you, so you will be able to come to an agreement.

Rui expected everything, but definitely not something like this. however, despite his worries, he accepted the mission from his king and left his office. on the day when dad Tsukasa left the kingdom, Rui started spending time with Tsukasa every day and getting along with him. However, the prince did saw Rui's soft side anyway.

it was a beautiful day and the first thing Rui heard after waking up was that the prince was looking for him throughout the kingdom, wanting to go for a walk with him. Rui agreed and soon went outside with prince, going into forest where he liked to be. Rui was in these parts very often, but despite this, they still encountered some small creatures that wanted to attack them. Rui, of course, wasn't afraid of them, but Tsukasa was terrified every time and he hided himself behind Rui.

"you have nothing to be afraid of, prince. I'm here to protect you, aren't I?" he said with his typical cold tone, holding his sword tightly in his hands.
