■ Name / Reiji Kizaki ■ Age / 21 (University Student) ■ Birthday / July 2nd (Cancer) ■ Blood Type / A ■ Height / 191cm ■ First person: I (masculine, calm) [Overview] Border's only Perfect All-Rounder. He became Chika's mentor after she joined the Tamakoma Branch, teaching her the mindset and techniques of sniping. He uses the Tamakoma-exclusive Trigger "Full Arms." Characterized by a sturdy physique described by Usami as "composed muscle," he is a veteran member who has been with the organization since the Old Border era, along with Konami and Jin. He gets uncharacteristically flustered around Yuri Rindo, another veteran from the Old Border days. According to the BBF, he is "not good at looking cool in front of the woman he likes," and Konami says this is "business as usual" for him, so that's likely the case.

He became Osamu's mentor, looking after him kindly by searching for teaching methods that meet Osamu's needs and introducing him to skilled fighters.
