Nero

The son of Remnya Scheduna and Nero Belladonna. He was born during the brief peace after the defeat of "The Four Executioners of Karx".

Like his mother, he was born with the natural ability to manipulate the Crimson Fire as well as being immune to it. Being a Nebrid (born from a pure female Nephilim and a male human) he is a prodigy when it comes to combat. Considered a battle genius, he's often overconfident about his skills, leading to showing off his power and mocking of his rivals.

He's the strongest out of the Children of the Advent, with the potential to rival veteran warriors such as Pestripe. He's thought to have the potential to become the strongest Nephilim on Earth. However, his easy-going personality, overconfidence, and laziness lead him to not train properly and getting distracted by mundane things.

He has a close friendship with Nikla and Marko but shares an even closer bond with Kana, whom he shares feelings for, eventually turning their relationship into an everlasting romance.
