Ten years ago, she went by her real name, Kyouko Mejiro (キョウコ), and was a member of a literature club at the school Nico Hirata taught the night class of.

When she was a teenager, she wore a school-uniform that consisted of a dark sailor-uniform and skirt. Her regular outfit was the same as the one she's wearing in the present.

Anko is a very straightforward, observant and extroverted woman with a, mostly, casual attitude who likes to mess around with others.

However, she can drop her casual attitude in the blink of an eye and quickly unsettle someone.

One of her most defining traits is her hatred for vampires. She is ruthless and determined to wipe them all out and exhibits sociopathic behavior. She usually shows no empathy when hurting them and is even shown to be highly sadistic and psychotic as she maniacally laughed while repeatedly stabbing Akkun in the gut.

As a result of her hatred for vampires she is also very determined to sabotage Kou's goal of becoming one, even offering her body to the middle-schooler should he choose to remain a human.

 * Knowledge of vampires: Having spent 10 years hunting vampires, she has gained a decent amount of knowledge about them. Because of her father's death, she knows of their weakness, which is being reminded of their human lives. Even without killing them, she knows of a few ways to survive an encounter with them.
 * Knowledge of weapons: She knows how to handle a knife and attacked Akkun and Hatsuka with one (Although it was useless against the latter since he could make his body phase through it). She also knows how to wield a gun, owning a revolver.
 * Foul tasting blood: Since she got her blood sucked by a vampire 10 years before the story started and didn't turn into one, it's now impossible for her to become a servant which makes her blood repulsive for any vampire who tries to suck it. She is aware of this and uses it to her advantage.
