I am Koharu is a side character of Najica Blitz Tactics. She is a Humaritt, and her serial number is "SSS". Koharu has shoulder length blue hair and red eyes. She has about the same height as Lila. She is seen in two different outfits. One is conservative traditional Japanese clothes consisting of a blue kimono, white cowl, white socks and sandals. Her second outfit is a modern one, consisting of a red jacket with white details, yellow zip-up shirt, green miniskirt and yellow cuffed boots. In both outfits she wears white panties. Like Lila Koharu doesn't show much of a personality but is simply loyal to her master and follows his orders without question and will not stop till she accomplishes her goal even after she is defeated and captured. She's aware of her small size and will use it to her advantage as she faked being hurt to get Najica to lower her guard. She is skilled with a sniper rifle.
