Asato, Ruka

安里琉花

Ruka is quite brash and behaves like a tomboy, which contrasts with Itosu, whose personality is the opposite of hers. She acts without thinking ahead, charging straight into battle against her opponents, which allows Black Lotus to defeat her swiftly.
However, she is very polite in the real world, as seen during her meeting with Kuroyukihime, and she holds high regard for her master and the rules he set for her and Itosu.
Ruka became the child of her master after he moved to Okinawa. After becoming a Burst Linker, she became a parent figure to Itosu, and the two are inspired to increase the number of Burst Linkers in their community.
