Yujin Akuma

**Yujin Akuma** is the son of Otosan Akuma and Hitokori Akuma, and one of two princes of The Underlands. He is the tritagonist of A Demon's Heart.

### Appearance

Yujin is a slender, skinnier demon. His horns are smaller than Nisu's, and his eyes are slits, similar to a snake's.

In Book 1, he wore an ice blue turtleneck bodysuit, with a darker blue section on the bottom separated by a light blue section.

In Book 2, he wore a light blue bodysuit with pointed shoulder pads and a dark blue section on the bottom.

In Book 3, he wore an aqua blue bodysuit with pointed shoulder pads and a dark blue section on the bottom, separated by a star.

### Personality

Yujin tends to be sarcastic and snarky. This prickly exterior is just a mask for how emotionally fragile he is, due to Otosan telling him that a true king dosen't show his emotions.

He actually cares quite a lot about about those close to him, often being sad when they are gone from his life.

### History

#### Book One

Nisu goes into the royal dining room, with Yujin and Otosan already there, claiming he’s late.

Yujin teases Nisu about his tardiness.

Later on, Nisu and Yujin become soulcatchers. Otosan takes the princes to Demon Mountain and introduces them to the Soul General, Gunso. Yujin seemed impressed by the soulcatching process, even praising Jokku for his work.

Later on, he sees Nisu sitting on a roof, and asks him why he isn't collecting souls. Nisu doesn't give an answer and brushes him off.

Returning home, Nisu has not collected any souls, and Yujin looks visibly concerned. When Otosan confronts Nisu about it, Yujin hopes he has a good excuse.

Yujin calls out to his brother, trying to stop him from the leaving the table.

In the final chapter, Yujin catches Nisu at Demon Mountain, and the two fight. Yujin breaks down, blaming himself for Nisu wanting to leave. Nisu corrects him, saying he was never the reason, and it’s mostly their father.

Suddenly, Otosan arrives.

Nisu reveals his plan to leave for good, and Otosan attacks him. Otosan almost defeats him, but Nisu fights back with a blast of fire and successfully escapes through a time travel portal. Yujin looks distraught, and Otosan tells him to go back to the castle, even threatening him.

#### Book Two

Yujin is seen mourning Nisu's absence, looking at his empty chair at the dining table. Otosan tells him to wipe his tears, and that a king never shows his emotions as it will make him as weak as the queen.

Later in the book, Yujin is telling Jokku what happened to Nisu.

Yujin says he dosent care about him, and is immediately criticized by Jokku, who tells him that Nisu is the only family he has left besides Otosan.

Then, Yujin and Jokku destroy a human village with soulcatching. Gankyu keeps a strange focus on him, creeping him out. He threatens him, telling him he better stay in line. Yujin threatens to turn him into a popsicle, and Gankyu dissapears.

#### Book Three

Yujin is the main protagonist of book 3.

He awakes in his room, with Otosan coming in. He tells him his presence is needed at Demon Mountain, to which he accepts.

Yujin also says he misses Nisu, to which Otosan mocks and laughs at him about.

At demon mountain, Yujin meets up with Jokku, who tries to comfort him about Nisu’s absence.

Yujin brushes him off however and continues to blame himself.

Soulcatching then begins. Yujin and Jokku hone in a human, who breaks down and tells them he has a family. Jokku shows mercy and lets him go.

Yujin deducts that soulcatching is wrong, since humans do live, think and act similarly to demons.

The two reconvene at Jokku’s house. Jokku figures that they should convince Otosan to stop soulcatching, to which Yujin says would be impossible without Nisu’s presence.

Jokku devises a plan to go to whatever timeline Nisu entered and bring him home.

Returning to Demon Mountain, Yujin opens a portal into an earth timeline. This one however, is a timeline where aliens have taken over earth. Jokku quickly gets the two in trouble, and they are attacked by hoverbots.

### Powers and Abilities

**Cryokinesis:** Opposite to Nisu, Yujin has the ability to manipulate and create ice from his hands.

* **Ice Claws:** Yujin's main weapon. He creates blade-like shards of ice at his fingertips, using them offensively.
* **Ice Shields:** Yujin can create defensive shields out of ice, and can even move them for offense.
* **Ice Board:** Yujin can create a "board" out of ice, and move it as an escape.

### Relationships

#### Nisu Akuma

Yujin is Nisu's brother, so the two seem to have an odd sibling rivalry. Later in book one, Yujin is revealed to have a high amount of respect and love for him, even grieving his absence. He even asks to leave with Nisu.

#### Otosan Akuma

Yujin has a desire to impress his father, hoping that soulcatching will earn him respect from him. He also seems afraid of him as well, immediately leaving as soon as Otosan threatens him.

#### Jokku

Jokku and Yujin have a mutual friendship. Jokku tries to comfort him after Nisu runs away, seeming to care about him.
