Trees guard the forests and the sanctified places.

Or in some cases, they guard people.

After returning to AM from Genua, Taiki Kimori had not received any news from his friend Aell. She never showed up for their appointment in OC either. Being worried of what might have happened to his friend in the dark and very dangerous Uberwald region, Taiki stayed in OC for further news. A week later Aell finally arrived, weakened and sick.

Aell explained she found out who her relatives were and that she had gained the title of dutchess in the village of Glitz. She explained her condition was due to an attack by six vampires. An attack she had barely survived. After recovery from her injuries, Taiki decided to be her guardian and ensure she'd be safe.

As result he has been granted the title Knight of Glitz.

Since Taiki considers Aell a close friend, he chose to become her guardian and ensure her safety until she'd be able to fight off vampires on her own. A remarkable thing to do for someone who lived his life so far as mercenary or bodyguard. Nevertheless it has happened and perhaps stems from the same conviction in which he deals with his family members.

If Taiki dies in the line of duty. He expects any of his family members to take his place and finish what he swore to protect.
