Yulha

The leader of Triangle, the Ark's foremost law enforcement and counterterrorism unit alongside the Central Government Army's First Squad. As Nikkes are prohibited from working in law enforcement, Yulha and her fellow Triangle Nikkes must keep their status a secret. Nigh-constantly swamped in paperwork for what Triangle has done or is going to do, Yulha sports a very distinct pair of bags under her eyes from endless all-nighters. She enjoys going out for a drink, though she can rarely find the time to do so. Yulha's shark-like teeth are surprisingly unique amongst Nikkes, as no other seems to have them. This also means whenever she bites, it's very clear just who left marks... An office worker that suffers from work overload. She is the leader of Triangle, and a reliable leader at that. Others inexplicably refer to her as Ghost.
