Namix Akiyama

Namix Akiyama is a female Demon that possesses the Chikara, Draconis. Namix was first introduced in the Shimetsukeru Arc when Kazega Eijizoyo and his team invaded Shimetsukeru. Namix was also the second Demon King.

Backstory
Namix Akiyama was born in an uncharted region of Thurlin among two dragon clans, Dokin and Rakin, being the first-ever born from two dragons from separate clans. Both clans came down on Namix's family as it was against tradition to have a child between two clans, hence the Elder deemed that Namix belonged to neither clan and thus she and her family were excommunicated from the clans. Soon after their excommunication, a small group of Demons took over the village, capturing all Dragonkin living there excluding the Akiyama family. The family, as they were leaving, saw smoke from behind and quickly returned to the village, only to find it nearly destroyed.

Namix, still a child, was told to stay behind by her parents near the entrance. However, Namix ended up secretly following in from behind, soon witnessing the capture of her parents by Demons. Fearing for her parents, her Chikara awakens and causes her to black out, killing all Demons present. However, she's quickly subdued afterward by a higher Demon known as Ozin. After the Akiyama family's capture, they were brought to Shimetsukeru before Akuma-Ara. Akuma, seeing Namix as a unique individual, gave her a choice: Namix could either join him as a Demon or join her family in a Ward to work for eternity. Namix, wanting revenge for her village's destruction, joined Akuma, ingesting his blood and becoming a Demon.

Shimetsukeru Arc
Namix is originally spotted by Kazega when running through Jigoku G. Namix, looking down over the courtyard, spots them in the corner of her eye, prompting her to pursue them. Kazega halts and enters combat with Namix, defeating her. Soon after Namix's defeat, she begins pleading for her people, claiming that if Kazega is as strong as he is, he should have no issue freeing them.

Kazega agrees to help her free the Dragonkin, plotting against the Warden of Jigoku G, Ozin.
