Tazuna Takatsuki

Tazuna (タヅナ)/Tazuna Takatsuki (高槻 手綱, Takatsuki Tazuna) is the lead protagonist of the series. He is the son of Mr. Takatsuki and Mrs. Takatsuki and the older brother of Musubu Takatsuki whose Hand Shaker partner is Koyori Akutagawa as "Single Gear" where they are known as Team Gear together.

Appearance
Tazuna has grey-ish brown-ish messy hair with light almost peach-colored tips. His eye color is green, with a small amount of blue around the pupils. However, when he summons his nimrod, his hair color is turned white with light pink tips, and his eye colors are a solid dark blue. His face gives off a young glow, and he has pale skin. He was first seen wearing his school uniform. 10 years after the battle, Tazuna's height increases, but his facial features hasn't changed.

Personality
In the 1st episode, it is pointed out that Tazuna has an unhealthy habit of fixing machinery or anything in general. He likes things that 'mesh together'. He's also very caring, as noted when he held his sister's hand before she passed away, and seems fine with having to hold Koyori Akutagawa's hand to keep her alive. He is also fearless, and would do anything to protect the ones he is willing to.

Nimrod
Tazuna's Nimrod allows him to manipulate gears that materialize out of thin air. He typically uses these gears to form a massive broadsword, which not only helps in combat, but also helps him and Koyori Akutagawa to speed around the Ziggurat quickly. Another common use of his Nimrod is a gear gauntlet, which primarily serves combat purposes.
