Barbatos

Barbatos, the Necromancer of Chaos. She actually seemed like a teenager dressed in gothic black dress, yet the voice that came out was that of a woman. (A playful voice rang out as Noah found the figure of a girl that seemed slightly younger than he was...)

She meets noah for the first time in chapter 167

First time with Noah in chapter 182

Barbatos was known as the Necromancer of Chaos, but that wasn't all for her. Noah looked through the memories of the undead skeleton warrior as he noted the habits Barbatos had maintained for years.

When she was angry, playful or even hopeful, she only had her undead to talk to. She expressed her inner thoughts to her lifeless companion, and Noah was walking past them now as he began to understand Barbatos better. He was sure of one thing as he watched her crazy life, and it was her hatred for the one person she couldn't challenge.

She uses the magic of the abyss to bind noah to a cooperative contract, whereby Noah must kill Baal within two months, while Barbatos will not claim or destroy Noah's belongings during this period.

Harbinger Of Gluttonny

Personality
Her personality in the start is playful but gets angry when they mentioned about Baal defeating her miserably that Noah uses to escape the predicament.

Barbatos however is lazy to the point she just want to have a nice bathe to the dismay of Emperor Penguin that was massaging her.

She also sometimes a pervert but she always lose to Noah when they are doing it. Also, she seems that she can keep up with Noah when they do it but in the end, she will fall asleep

When Noah is having a gap in power for both to his friends and people, Barbatos realize that she don't need to be strong to stand beside Noah but get her superiority through love because she is a genuine wife of Noah.
