Tamakoma First

"Border's strongest squad is already on its way."

- Masafumi Shinoda about Tamakoma First in Chika Amatori 4.

Tamakoma First, also known as Kizaki Squad, is a Border Team. It is led by Reiji Kizaki. Each member has their own unique Trigger, which is different from HQ's Normal Triggers. They are not allowed to participate in the Team Rank Wars due to these Triggers being unapproved Neighbor technology. Shinoda also called them "Border's Strongest Squad." Jin used to be a member of this squad prior to receiving his Black Trigger, although he did not return to it after relinquishing his ownership of Fūjin.
