All through English, I considered all the positives and negatives of telling Lysander the truth.
Cons:
Risk of getting 'Reaper Chopped' by Lord Death, getting kicked out of the Academy, and risk of Lysander hating my guts and never speaking to me again.
Pros: No more guilty conscience.
Well, the possible negatives definitely outweighed the positives, but my instinct told me- no, more like screamed at me- that telling Lysander the truth was the best choice.
-Later-
My heart was pounding, my head felt light, and my palms were kind of clammy, ew, as I walked into the science room. Lysander was sitting in his usual spot, gazing out the window. I sat down in my desk beside him and he looked over at me with a small smile. Maybe he's not mad at me.
I smiled back at him. "Hey, Lys" I started, "I was wo-" before I could get the words out, I was cut off as the teacher came into the classroom and started rambling on about something-or-other.
Frustrated, I tore a sheet of paper out of my notebook and quickly wrote:
I was wondering if I could talk to you after school.
When I finished, I folded the paper and placed it on Lysander's desk when I thought the teacher wasn't looking. When I did, he looked at me curiously before turning his attention to the note. After a few seconds of writing, he passed the note back.
Sure, where?
Good question. It had to be somewhere that nobody could listen in.
The park?
Lysander agreed that he would meet me there after he dropped off his things at home. For the rest of class, I concentrated on pretending to listen to the lecture, while my gut was twisting with anticipation and nervousness.
-Lysander's POV-
I knew exactly when she walked into class, though to keep from staring I switched my gaze to the window. She looked tiny and fragile and I was still kind of worried about the cut on her forehead, though Castiel assured me that someone like her could take a lot more damage than that.
When she sat down at the desk beside mine I turned and gave her a small smile. She returned it and said "hey Lys, I was wo-" but she was cut off when the teacher came in and started his lecture.
She let out a small, frustrated sigh and took a sheet of paper out of her notebook. Assuming that she was writing notes, I focused my attention on the lesson. Suddenly, a folded piece of paper landed on my desk. I looked at Aria, the one who placed it there, curiously then un folded the note.
I was wondering if I could talk to you after school. it said.
Was this about what Castiel had told me? I quickly wrote a response:
Sure, where?
Aria paused for a moment, thinking.
The park? she wrote.
I agreed, but I had to stop at home first to drop off my things, and because Leigh would worry if I went somewhere without telling him. He was like that a lot, but I didn't blame him we had no other family, so we'd been living alone since I was twelve.
For the rest of class I watched the teacher without really paying attention to what he was saying, I was too anxious about what aria wanted to tell me.

-Aria's POV-
It wasn't until the last bell had rung that I remembered that today I had training with Castiel. We usually walked to my place right after school, so all I had to do was wait for him by the doors.
"Hey, short-stuff. So, what are we doing today? More hide and seek? I was thinking we could play tag this time." Castiel said, coming up behind me with his ever-present smirk.
I sighed, some of my annoyance surfacing. "Sorry Castiel. Practise is going to have to wait. There's something important I need to do. I'll need you to come by around six, okay?"
He didn't even seem mad. Usually he was way too impatient when it came to training. "Fine fine, I got it. I'll see you at six." Then he walked off in the direction of his house, a devious smile on his face.
He'd better not be planning something, or he going to have to do ten laps around the neighbourhood. I thought as I walked towards the park.

Thirty minutes later I was sitting under the tree where I had sat with Lysander. I was staring off into space, not paying attention so when I felt someone tap my shoulder, I let out a little squeak of surprise and turned around to meet Lysander's mismatched eyes.
"Sorry, I thought you would have heard me." Lysander said, chuckling at my expression.
How did he move so quietly? "It's alright." I said with a nervous laugh. Man, this isn't going to be easy.
"So what did you want to talk about?" Lysander asked, sitting down beside me.
"Well, first I have a question." I had a bad habit of fidgeting my sleeves when I was nervous, and right now, it was as if they were the most interesting things I had seen in my life.
"Okay, go ahead." He urged me to continue.
"We're friends right? I mean I know I've only been here for a while, but do you trust me?"
I looked up at him and saw something like sadness flash across his face, but it was soon replaced by a half-smile. "That's two questions." He said.
"The answers would mean the same thing." I said, knowing that he was stalling.
He sighed, "Yes you're my friend, and yes, I trust you. Now what did you want to talk about?"
My heart was beating so loudly I swear he could hear it. "Do you promise you won't get mad?"
"That depends." He said
I let out a long, frustrated sigh. "I seriously don't know how to explain this." I mumbled, more to myself than to him. "Lysander, what do you know about the DWMA?"
Lysander paused before answering, "Well I know that it's an academy where Weapons and Meisters are trained to fight, right?"
I nodded. "do you know why Meisters and Weapons fight?" I asked.
"Something about keeping balance between souls, isn't it?"
"It goes deeper than that. The Academy was created by the Grim Reaper, to hunt, and prevent the creation of Kishin Souls." I said, remembering the speech Lord Death had given at the entrance ceremony.
"Kishin Souls?" Lysander inquired.
"They are creatures, demons that are created by devouring innocent human souls in order to gain power." I said.
"How do you know all of this?" Lysander's face was serious, but I could see curiosity in his eyes.
I swallowed, "Well, that's because…" I trailed off. Was I really going to tell him?
"It's Because Aria-Chan is a Meister!" called a voice behind us.
Both of us turned around. There, suspended in air was a woman. Her hair was the color of emeralds and her eyes were as dark as the night sky. She wore a long, deep blue skirt that ended at her feet, and wrappings that covered her torso, arms, and covered from her nose down, concealing most of her face.
I stared at her in shock. How did she know me? and how was she just hanging in air like that? I searched for her soul wavelength, but felt nothing. When I searched other people for the Weapon's wavelength, it was just normal. From this woman, I felt nothing. Then I realized it. Soul Protection. She's disguised her Wavelength. No way. This can't be happening. I haven't found the Weapon yet, how am I supposed to win against HER?
Lysander looked at me and said, "Aria? Who is this woman? How is she doing that?"
I looked at Lysander, pain twisting my chest, knowing that I had dragged him into this. No matter what, I won't let him die here. I'll hold her off as Long as I can for him to get away. After all, it's the DWMA's duty to Protect innocent souls.
I steadied myself, and took a deep breath before answering him. "She's a Witch."
