Crimson Kingbolt

クリムゾン・キングボルト

Crimson Kingbolt has a relaxed personality and is willing to spend his burst points to help Itosu and Ruka level up. He cares deeply for the two, as he is prepared to stall Sulfur Pot to allow them to escape if necessary.
He originally lived in Tokyo, where he was friends with Black Lotus. However, he moved to Okinawa after his parents divorced. After moving to Okinawa, he became a parent to Ruka Asato, who later becomes a parent to Itosu Mana. He became a "master" to both of them, teaching them the rules of Brain Burst. He also gave them both rules to always follow: never use acceleration for selfish purposes, and only talk about the Accelerated World to other Burst Linkers. He is also a high school freshman.
