Commander of "Black Lizard"
Tachihara is a slightly imposing boy with short, spiky brown hair and small amber eyes. He also has a bandage going across the bridge of his nose.
His normal outfit consists of a long-sleeved and rather baggy white v-neck shirt with the border being black and the right sleeve rolled up so it isn't visible.
This shirt is partially covered by a military green crop jacket that has beige fur around the collar. He also wears dark blue pants, brown boots, and a black band on his right wrist.
