Deca

**Deca** is the brother and other-half to Orochi Yamata. He was born when Orochi had split his mind due to an 'error' with Memory Partition. The new personality was then turned into the Skill Divided Mind.

Deca was named during the events of Abyss Unleashed which resulted in him fully separating from the housing of Chokmah and evolving into a digital-nature called a Manas.

## Appearance

Before getting his own body, Deca shared one with Orochi. Whenever he would get to pilot one of Orochi's body doubles, Deca would tie his hair into a ponytail, and the purple markings around his eyes point up instead of down, like Orochi.

After getting to modify his own body through Orochi's Enhanced Body Double, he morphed Orochi's body into someone else entirely. Unlike Orochi who preferred a more monster appearance, Deca was more fond of a human's form. And in that form, he has straight-edged black hair of varying lengths, the longest reaching down to his shoulders and the shortest stopping at his cheekbones, which he wears down with two shorter strands hanging between his eyes. His eyes are almond-shaped and tilt upwards on the far sides, and are unusual due to Deca possessing heterochromia—his right eye is naturally yellow and his implanted left eye is turquoise.

He wears a navy blue buttoned shirt with a white framed collar, a shirt pocket on top of the left breast and white undershirt. It also consists of long, saggy tattsuke-hakama pants strapped by a white buckled belt that can be optionally tucked in with any kind of Kyahan that extends into tabi socks. Along with a black and white pinstriped haori, the hem and cuffs of which are striped length ways rather than vertically, which covers his hands. Deca also sports bandages in place of the leg-wraps around his calves, as well as white with blue-strapped zōri on his feet. He is also always seen with his white snake, Kabuto, wrapped around his shoulders.

## Personality

Deca is an energetic and optimistic boy who has the constant drive to improve himself, even when he was still just a skill without an Ego. He is confident in his skills and always seeks to challenge others to prove his abilities and test the limits of his prowess. Because of this, Deca constantly finds himself in very difficult situations in his various duels and challenges which would break the spirits of most people. However, he remains positive and cool under pressure, never backing down from a challenge and is always constantly thinking and evolving his abilities.

Deca is also flexible and innovative, able to break away from ordinary procedures to develop new skills, thus allowing him to make his own solutions when he needs to find an edge. As such, he can create some of the most unorthodox, but also incredibly effective techniques no one has never seen. From his time within Orochi*,* Deca toyed with Architect and the skills contained within him. It was his personal hobby within Orochi's soul to rearrange skills and fusing them in different ways, finding out all possible combinations, as it was his only form of entertainment before acquiring his own body. This lead to Orochi's massive boosts of power, and acquiring skills he wouldn't have obtained otherwise.

## Chronology

Deca was born from Orochi's uncontrolled thought partitioning, that, when it attempted to fuse back together, caused his mind to split into two. The one who was there from the start, and the extra personality. Deca possessed memories from before Orochi's reincarnation, whilst Orochi lost them but kept the ones he made since the start of his reincarnation.

During Orochi's evolution to Mystic Naga, Divided Mind acted on it's own to make full advantage of the evolution process to evolve Orochi's Extra and Common Skills using his Unique Skill Architect. It was during this that Divided Mind evolved into Parallel Mind, possessing a simulated personality. At the end of the process Orochi obtained 5 new Extra Skills, one of which was the evolved form of Parallel Mind, Administrative Assistance.
