Tamakoma First (玉狛第一,Tamakoma Daiichi?), also known as Kizaki Squad (木崎隊,Kizaki-tai?), 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 battles due to these Triggers being considered too powerful, and 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.
Shinoda sends Tamakoma First to aid Osamu after Kitora is cubified by a Rabbit. They are easily able to deal with the new Trion Warrior, but Hyuse and Viza soon come along. At this point, the members are forced to split up; Konami pursues Trion Warriors heading toward civilians, Karasuma helps Osamu and Chika flee from the Neighbors while Kizaki faces the two himself.
