I finished the ritual, and now I just need to say this one last line.

"And I summon this demon, with intentions good, and bad," I said finally as there was smoke everywhere in my bedroom. I coughed, and coughed until the white smoke vanished. I looked up, and there was a male demon. He had (s/c) skin, (h/l) (h/c) hair with light strawberry blonde streaks almost all over them, and amber mixed with (e/c) eyes. He also had a moon tattoo on his head. The attractive young moon demon named (Y/n). From rumours spread across the land, he's extremely attractive, and can grant you any wish.

"You summoned me?" The moon demon asked me.

"Yes, I summoned you!" I exclaimed, flabbergasted at its beauty.

"What intent do you have to summon me?" He asked.

"Uhm, I dunno, I just wanted to see if the rumours about you being pretty are true," I explained.

"Oh... well, I can't leave until I grant you a wish, so what do you truely, and solely desire?" The demon asked.

"Uhm... are you a genie?" I asked.

"No? I'm a moon demon named (Y/n)." (Y/n) chuckled. "But do you have a wish?"

I thought, and no actual wish came to mind. "No, not yet." I told him.

"Well, I can't leave, so I'll have to follow you around," he told me.

"Will people see you?" I asked.

"No, only you'll see me. Also, why are there rumours about me being pretty?"

I shrugged. "I'm not sure, but a bunch of people who summoned you in the past said you're pretty. They also said in order to summon you, they'll need to have a lot of bravery," I told him.

"Weird, it's not like I'm Lucifer or something. Anyway, I'm going to sleep, bye." (Y/n) said as he crossed to the other side of the room, and slept in the air.

"Are you sure?" I asked him.

"Yep. Goodnight... uh what's your name?" (Y/n) asked as he chuckled.

"My name is Terushima Yuuji, but call me Yuuji, I don't mind," I informed him.

"Alright, Yuuji, I'll see you in the morning!" (Y/n) exclaimed as he fell asleep.

...

The next day came, and I went to school as normal for morning practice.

"Good morning, Yuuji!" I heard a voice exclaim. I turned around to see (Y/n) float behind me.

"Oh hey, (Y/n)." I greeted as I smiled.

"Where are you going?" He asked.

"School. I have morning practice today." I told him.

"Cool!" He exclaimed as he smiled at me.

"You know, you don't seem like a demon. You're really nice," I told him.

"Really? People say I'm a little too bubbly." He said as he scratched the back of his head.

"I think you're just fine," I said as we arrived at the gym.

"Hey Terushima!" Bobata greeted.

"Hey Bobata!" I greeted him back as I put my stuff away. "Go change, practice is starting soon," Bobata said. I nodded, and walked into the changing room.

"Wait here, (Y/n)." I told the demon.

"OK!" he exclaimed as I walked into the changing room.

I changed into my practice uniform quickly, and went to the team. Actually, (Y/n) followed me back to the team, but I acted like he wasn't there, just to avoid suspicion.

"Alright, let's practice!"

We finished up practice, and I told the team that I'll clean the gym. I cleaned it up with the help of (Y/n). Whoever spread the rumour that (Y/n) was pretty, they were completely right. His (h/c), and strawberry blonde hair glowed with the orange lights in the gym, and his amber, and (e/c) sparkled with innocence, and joy. That's when I realized; I fell for the charming moon demon.

It's been months since the realization. (Y/n) was still around, helping me, and stuff, but I didn't mind. It was great that he helped me out, otherwise I'd be dead. It was math class in the afternoon in October, and the sun was extremely bright.

"It's so bright," I mumbled.

"It is." He agreed.

"Can you block light, since you're the moon demon?" I asked.

"Yeah, I can." He said as snapped his finger. Suddenly an eclipse happened, which shocked my teacher so much, he called the police.

"What the- there's an eclipse!" Bobata shouted.

"Whoa, you did that?" I asked (Y/n).

"Damn right I did,"I did." He said.

"Wanna go outside to check it out?" I asked.

"Hell yeah!" (Y/n) exclaimed as we both ran to the back of the school.

"This is awesome, whoa! Wait, hold on don't you need sunglasses for this?" I asked him.

"To the normal eyes, yes, but I made sure that you can look at it with the naked eye. You are my priority." (Y/n) smiled. I blushed and nodded.

"Thank you." I thanked him. "Hold on, I think I have a wish!"

(Y/n) looked a bit disappointed, and smiled.

"Alright, what would you like then, Yuuji?" He asked.

"I want you to stay with me forever." I told him.

"Uh, are you sure? I'm a demon." He said.

"Yeah, I'm pretty sure. Please stay with me, I love you," I said as I grabbed his hand. (Y/n)'s eyes sparkled with joy, and he smiled.

"Yeah, I love you too. And sure, I'll stay with you,"

I then grabbed his torso, and kissed him roughly on the lips, to which (Y/n) kissed back.

"I love you..." I whispered.

"I love you too," (Y/n) whispered back as he caressed my cheek.
