フリッツ・ハールマン

Mora's companion and a vampire hunter who is good with various firearms and explosives.  Additionally his skills as a hacker are top notch. Fritz is a cold-hearted and sarcastic man who never fully trusts Souta, mainly because the latter is no longer a human being. Basically he treats Souta as a hound to smell out vampires. 

Fritz drives a Hummer, his favorite weapon is the "M4 Witch Hunter Special" (with UV floodlight and bow gun that shoots silver arrows). He is named after a real German serial killer Fritz Haarmann. 

Fritz is actually Mora's older brother. Fritz threw himself into a tough battle for her sake. They left their hometown together after Mora was being oppressed and discriminated against due to her being a Dhampir. /
