Hello. I'm sorry this chapter is so short. I hope you are enjoying the story so far.

To anonym user: Thanks for your comment! And I'm afraid there won't be many moments of LuciYuki because of the important plot. Even so, I'll give you some scenes.

Chapter 03 [Rin POV]

I went on a walk and, when I returned to my room, Yukio wasn't there. I supposed he was busy with work or something like that and I didn't worry too much. But he didn't come back even at night. Where was he? I couldn't help but feel anxious. He never left without telling me where or why. It was very strange.

I asked all my friends if they knew anything about him, but all of us hadn't talk to him in days. Knowing how Yukio was, he surely was involved in something bad. I couldn't stay without doing anything.

Even Shima refused to tell me nothing, but I had a feeling he knew more than the rest of us. Shima was a spy of the Illuminati, so if something happened with them he wouldn't tell us.

So... Was Yukio involved with them? Then, it was really dangerous. We didn't even know where the base of Illuminati was. We could do nothing, and that fact annoyed me a lot.

When I saw Shima some days later in the corridors, I asked him once more.

''Are you sure you don't know anything?''

''Yeah.''

''Please, Shima. I'm worried, and everyone is too.''

Shima sighed and looked away.

''Well... I do know something. But I don't know if I should tell you.''

''Please. I'll do anything!''

''...I guess there's nothing that would change your mind, huh? Okay. I'll tell you.''

Shima explained me that Yukio was in the Illuminati now, and he was dating Lucifer. I couldn't believe it. What the heck was that idiot doing?

''Okay, thanks.''

I left. I needed to think. All that story was giving me headache. Yukio was really dumb. Why didn't he tell me anything? ...Well, I suppose he couldn't. I would try to stop him at all costs.

How could I find him? Just where was he?

Then I recalled something. Maybe Mephisto knew the answers to my questions. After all, he knew Lucifer more than me.

I ran until I arrived to Mephisto's office. I entered it without asking permission, and he looked at me with a disappointed expression.

''Mephisto!''

''What do you want? I'm tired.''

''Where is Yukio!?''

''Why should I know?''

''You know where Lucifer is, right!?''

''I don't.''

I opened my mouth and then shut it again.

''Y-you don't?''

''No.''

He laughed a bit to my reaction and I just looked away, ashamed.

''Then... how can I find Yukio?''

''I don't know. You should just wait.''

''Wait!? Are you telling me to wait when Yukio is with that freak!?''

''Silence. My hands are full with this too.''

I gritted my teeth and walked away. I felt really impotent. There was nothing I could do for my brother. But... if something like what happened to my father happened again... I wouldn't be able to bear it.

''Rin?''

Shiemi called me and I turned to see her with a terrified look on her face.

''Shiemi, are you alright?''

Some tears started falling down her cheeks, and I was really confused.

''Yukio... I saw Yukio...''

''What!?''

''I... H-he was...''

I gently hugged her, trying to calm her even a bit. After some minutes, she stopped crying and I released her.

''Are you okay?''

''Yes... Yukio was wearing the uniform of the Illuminati.''

''What!?''

''He looked... very different. I was afraid and I didn't talk to him, but... I don't know what to do...''

''Okay, where was him?''

''Near the forest around my house... I think he was in a mission for the Illuminati.''

''Great. I will try to chase him.''

''Really?''

''Yeah. Just wait for me! I will bring him back no matter the cost.''

Shiemi nodded with a puny smile and I started running (again) towards the forest. I didn't know how would I react when I saw him, but... Now I could only go after him.

Once I was in the forest, I immediately heard some gunshot sounds. Without any doubt, that was Yukio's guns. I searched the origin of the sounds and I saw him. My brother Yukio. He was with a girl I saw before, one of Lucifer's bodyguards, doing some kind of training. He was working very hard.

Shiemi was right. Not only the clothes, but his expression had changed a lot. He looked... determinate and confident. I never saw him like that. I felt strange, and didn't have the courage to talk to him. But eventually, he and the girl with him noticed I was there.

''Rin...''

Yukio and I were face to face, both of us surprised and confused.

''Yukio... why?''

Yukio looked away.

''Answer me!''

I was angry now. Why didn't he trust me even a little? It was always like that. No matter how much I tried to help him, he tried to do everything alone and solve his problems, even if this destroyed him completely. I hated that part of him. I really wanted to help him even a little.

''I... I won't return to the Academy. Don't try to stop me.''

''But... why are you doing this? I thought you were on our side...''

''Sorry.''

''Is it true that you're dating Lucifer?''

''...Yes.''

''Goddamit, Yukio! Just what the hell are you doing!? This isn't like you at all!''

''Shut up!''

I felt chills over my skin when I heard him shout. He, who was always serious and calm...

''I can't understand it.''

''You don't need to, Rin. This is my decision.''

''Your decision!? Don't talk as if this had nothing to do with me! Why can't you trust me once!? We are very worried!''

''I don't care.''

I was no longer angry but sad. It really made me sad to see I didn't mean too much for him. Lucifer was more important than me. I, his brother, who lived with him all that time, meant nothing.

''Aren't you aware of what are you doing?''

''I am.''

''Lucifer has killed a lot of people. Do you really agree with that?''

''It doesn't matter if I agree or not. I love him, and I know he has great motives to do so.''

''The motives don't justify the things he is doing.''

''Who are you to say that? You also hurt a lot of people. Lying to your friends. Even I couldn't stand you anymore.''

''What are you saying? Don't compare lying with killing.''

''What's the problem? You want to kill Satan too, right?''

''It's not the same!''

''Yes it is. Killing is just killing. No matter who.''

''No, you're wrong!''

''I'm not. Even you... I will kill you if it's necessary.''

I couldn't believe it. Did he hate me that much? I looked towards the girl that wore an uniform similar to Yukio's, and then towards Yukio again.

''Okay... I realized I can't bring you back. Then... I swear I'll beat that Lucifer and you'll come back, even if you refuse!''

''...Do whatever you want.''

''Yeah! And don't you dare saying you'll kill me again!''

''Brother... stop it.''

Yukio and the woman left and I sighed. I was disappointed, and I didn't expect him to act like that. That was just how much he liked Lucifer.

I returned to the Academy and explained the situation to Shiemi and the others, trying to sound as calm as I could. They ended up saying things similar to what I told to Yukio, and we decided to defeat Lucifer together. Shura offered us her power too, and we talked to Mephisto to request help from stronger exorcist such as the paladin, Arthur Auguste Angel. I didn't like him at all, but his power was necessary.

Bit by bit, we were gaining more allies, and I started to feel confident about this. Still, the fact Yukio betrayed us hurt me. I wanted to help him, but I didn't know if I could do that.

By the moment, I trained myself more than before, without resting even a second. Day by day, my trainings were difficult and tiring, but I never gave up.

I knew the battle was close. I knew I had to win no matter the cost. So I was so concentrated on the training I didn't realize what was happening to me... and to my friends. Things wouldn't go as I expected.

One day, I was eating with all my friends in the dining room. The ambience was very depressive, and no one was in a good mood. Shima made some jokes, but no one answered him.

In a certain moment, I heard something strange, but I didn't know what it was. Suddenly, the door of the room blew up, making some of us scream in fear.

When I stood up and looked at the now destroyed door, I saw something I didn't want to see at all. Lucifer... and his bodyguards, including Yukio. He didn't look at me. In his eyes, I noticed nothing but his will to protect Lucifer.

Shura and some teachers remained in front of us, planning to talk with Lucifer. Me and my friends just watched the scene in silence. I was too shocked to say anything.

''Good afternoon.'', Lucifer said.

''Why are you here?'', Shura asked to him.

''I'm here to give you an advertisement. Specially to Rin Okumura.''

He glared at me and I swallowed hard. He was really scary. To think Yukio and him were going out... it was so... weird.

''Tomorrow, at 4 pm... The army of the Illuminati will come and destroy everything in this building.''

''What!?''

''Yuki!'', Shiemi called him, and Yukio looked at her, ''Yuki... Why...?''

She started sobbing and I knitted my brow. I was getting very angry.

''Yuki... Please don't do this...''

''That was what we wanted to say. We'll be going now.''

Lucifer and the others left, leaving us alone and broken. I caressed the shoulders of a crying Shiemi while the others just looked at the floor in silence. Shiemi hugged me and I accepted the hug. He was really, really sad.

''I won't forgive Yukio for this'', I thought. He made Shiemi cry, and that wouldn't cost him cheap.

I had only one day. Only one day to win the fight against an entire army of professionals and demons. It wouldn't be easy, but I had to do it.

After another heavy session of training, when I returned to my room at night, I saw something I'd never expect. That guy... the one with green hair, the demon that hated me so much... How was he called? Kamaimon? He was there, sitting in Yukio's bed.

''Hey! Kamaimon! What are you doing here!?''

''My name is Amaimon. And I was ordered to be your new roommate.''

''NO! You must be lying! I have to live with you!? I'd rather die!''

''Shut up. It's not like I want to be with you either, but we don't have nothing to do against Mephisto's orders.''

''That shitty Mephisto...''

Kamaimon crossed his arms with a lollipop in his mouth.

''I heard you will be fighting Lucifer tomorrow.''

''Yeah.''

''I would recommend you to give up. He's a hundred times more powerful than you.''

''I don't care what you say. I will win.''

''You seem pretty confident. Well, I'll be watching too, but I don't care about the results too much.''

I sat, ignoring him and starting to read a magazine.

''Rin Okumura.''

''Hm?''

''Don't die.''

I smiled ironically.

''I won't.''

And then, the tomorrow came. The battle was near...
