Hey guys! I'm editing the first few chapters of this story, since I felt like I kind of rushed the background of Yumi. I hope you enjoy this edited version of chapter 1!

Notes: Pairings are Hecadoth x OC, Furuichi x Agiel, and an established Oga x Hilda. The title means 'The Half-Breed Girl'.

Chapter 1- Putting My Walls Up

I arrive at St. Ishiyama Academy, wearing the girls' uniform, a thick black headband in my brown hair that flows past my shoulders. I take a deep breath and walk towards the school. I've heard that the special class, the class I'm transferring into, consists of delinquents from the sister school Ishiyama High School. I stare up at the school in determination. Okay, Yumi. Remember. Do not lose control. You don't want a repeat of what happened in Edmonton.

My name is Tanaka Yumi. I'm an eighteen year old, Japanese-Canadian third-year high school student who has just moved from Edmonton to Ishiyama with my dad, Tanaka Tomohiro. I look like a normal Japanese girl with brown hair and amber eyes. However, I'm not normal. I'm far from a normal human. And for that reason, I don't get close to anyone.

"Sheesh, this uniform is just too constricting!" A girl's voice sighs in annoyance as I walk through the hallways.

Raising my head up slightly, I see a girl with crimson-red hair in two braids and a guy with long, slightly unruly black hair, both of them wearing the St. Ishiyama uniforms. I can only see their backs, though, so I can't tell who they are. However, I can sense a demonic aura from them, increasing my suspicions even more.

"We have no choice, Agiel," a male's voice says. "If we're supposed to be moving in with him, we have to get used to wearing such uniforms and acting like high school students. If we wear our standard uniforms, people will become suspicious."

Huh? Who could they be? I wonder. Although, the name Agiel sounds rather familiar. As if sensing my presence, the two of them turn around to face me. Right then, I notice the fish ears on the male as well as the black tattoo on his face, and it hits me. These two are Pillar Generals from Behemoth's 34 Pillar Division!

"Yo," the black-haired male says. "Who're you?"

"Huh? Oh, I'm Yumi," I introduce. "I'm new here. You?"

"I'm Hecadoth," the male introduces.

"And I'm Agiel," the girl greets, smiling at me. "You're kind of cute, you know?"

I raise an eyebrow. "Uh… thanks…?" I thank, unsure of how to respond to such a comment.

The rest of the walk to the class is silent. Eventually, we reach the special class and walk inside. I see our teacher, Saotome-sensei, at the front of the classroom. "Alright, brats! We have three transfer students in our class." He gestures to Hecadoth and Agiel. "First off, from Macau, this is Hecadoth and Agiel. Agiel will be transferring into the second-year, and Hecadoth will be transferring into the third-year."

The two of them bow and sit down in empty desks.

"And from Canada, transferring into the third-year, this is Tanaka Yumi," he introduces me. I give a slight bow, smiling slightly before going to a desk and sitting down. Right then, Saotome-sensei starts the lesson for today.

"Tanaka-san," he suddenly calls on me. "Solve the problem on the board." He taps a math equation that's been written out on the board. I go up to the board, picking up a piece of chalk. I then start to write down the solution, step by step, finding it pretty easy since I had done this particular unit before. Once I finish, I sit back down without a word.

When the lunch bell rings, I decide to go to the library instead of eating my lunch. While I walk to the library, I see so many students walking around with a particular group of friends. Practically everyone is friends with someone. And here I am, someone who has no friends. Not that I care. I'm better off without friends. If I make friends, if I let people in, I'll end up getting too attached, and they'll get hurt. I don't want to see people getting hurt because they got involved in my current problem. Not only that, they might not accept me if they find out what I really am.

"Tanaka-san." I turn and see Principal Isurugi. "Come to my office. I need to talk to you."

"Uh… okay…?" I trail off as I follow him.

Upon reaching the office, I'm surprised to see Dad here. "Dad? What are you doing here?" I ask.

"I feel that I need to be here for this," Dad tells me.

Principal Isurugi sits down behind his desk and I stand in front of the desk. "What is it that you need to talk to me about?" I ask.

He looks up at me with serious eyes. "We need to warn you," he tells me. "You are in grave danger, Tanaka-san."

"Huh?" I ask, confused. "I'm… I'm in danger?"

He nods. "You lost control and you were expelled from your school in Canada as a result," he says.

Wait, how does he know?! "How… How did you know?" I ask, now wary.

Dad smiles slightly. "I was a former student here, remember?" he recalls. "I told him about the incident and he allowed me to enroll you here, Yumi. Besides, you'll be safer here. There are others like you here as well, especially in the special class."

I nod slowly. "Who's coming after me?" I ask. "And why?"

Principal Isurugi lowers his eyes solemnly. "A group of demons that severely hate your kind," he says. "The same one that abducted, tortured, and murdered your mother."

My eyes widen in shock. "But… why?"

"They want to finish what they've started," Dad says tersely. "Ever since you lost control, they now know you exist and now, they will stop at nothing until you're dead. So please, don't lose control ever again."

I nod. "Y-Yeah…"

"You're free to go," Principal Isurugi tells me. As I walk to the door, he calls me again. "Tanaka-san, just one last warning."

"Yeah?"

He gives me a serious look. "Do not ever fight them, even if they confront you." He says this as an order.

As I sit in class, I can't help but silently thank Principal Isurugi in my head. I really owe both him and Dad a lot. So to repay them, I will keep control of myself, even if it costs my life.
