Rina Kirigakure

Ouka's apostle. She is one of Canterbury's paladins and is assigned to serve as Syu's bodyguard. Older than Syu by two years, she is another of the Kirigakure clan whose destiny is to serve the Amatsu for life. From young, she has served him and is his betrothed, wedded life is something she has looked forward to with great anticipation.

Spoiler

Despite knowing Syu from a young age, she has never realised his burning desire to fight at the frontline the same way she does.

Her powers revolve around sonic vibration. Unlike Zephyr Colerain, she can enchant her weapons to deliver devastating blows that can destroy just about anything.
