Zanku

Zank the Beheader was a notorious serial killer. He was known for severing the heads of his victims, as his name implies. Night Raid was contracted to track him down and kill him.

Bio
He was originally an executioner for one of the Empire's prisons, but went mad from guilt over the high-rate of his executions. He showed symptoms of Schizophrenia, hearing dark voices that drove him closer to insanity with each day. He eventually escaped his position after stealing the Teigu, Spectator. He was wanted by the Imperial Guard/Defense Forces ever since. Zank began his rampage, killing random individuals throughout the Empire to sate his blood lust, beheading his victims. Soon, Night Raid was contracted to assassinate him. Akame and Tatsumi both fought Zank, and after a struggle he was defeated by Akame, and was finally able to find peace as he died.

Equipment & Skills
Zank was the user of the Spectator Teigu, a headpiece that allowed him many mental abilities, including hearing the thoughts of others, and accurately predicting their next move. He uses a pair of hand blades that look like Katars to cut his opponents ruthlessly.

Trivia
After Zank was killed, Night Raid took the Teigu back to their base, where Tatsumi briefly tried it on with comedic results. After it rejected Tatsumi, Night Raid sent it to Revolutionary Army HQ for safe keeping.
