I suddenly wake up In the morning, because somebody opened the door with a bang.

"Nee-chan, wake up! Breakfast is ready!

I look at the door and see Sally there. At the same time Sariina gets up and looks around confused. Sally than notices that I and Sariina are both naked. Sariina is finally fully awake and says:

"Okey. We will come down shortly."

"Okay Nee-san.Btw Nee-san, what did you and Lucifer do here yesterday? You were so loud!"(Sally)

Sariina starts blushing and her face is as red as a tomato. She is so embarressed right now, that she can't say a word.

"You don't need to know right now. When you become older, ask your parents."

I answer to her and she says:

"Okay Lucifer."

She then turns around and leaves the room. Sariina is still embarressed. I start patting her head, so she would stop thinking about it. She then looks at me and says:

"Even though I'm 6 years older, you always take the lead."

"But you like it. Don't you?"

I say that to her and start nibbling her ear.

"Nyaa! Luc nyaa! Stop it. We just waked up."(Sariina)

I stop nibbling her ear and say:

"You can take the lead tonight, if you want."

"I'll think about that."(Sariina)

"We should get up now."(Lucifer)

"Yeah!"(Sariina)

We get up from the bed and get dressed. While dressing, she says:

"I want to become an adventurer.Just like you."

"Okey! We can go register at the guild after breakfast."

"You are not against it?"(Sariina)

"Why shoul I? If you want to become an adventurer, I have nothing against it. Now get dressed. We have to go downstairs."

I say that to her and we finish dressing. I wear the same clothes that I wore yesterday and she puts on her clothes, except the leather coat, that we bought some days ago. We leave her room and go down to the dining room.

"Good morning everyone!"(Lucifer and Sariina)

"Good morning dear!"(Maya)

" You are finally here. Sit down and we can start. We sit down and start to eat. Nobody is saying anything. I start drinking my water when Maya says:

"I know you are lovers, but try to keep it down. I think the entire mansion heard you."

'pffftt'. Were we really that loud. Me and Sariina start blushing. This is fucking embarressing.

"You did it for 4 hours straight and we could hear Sariinas 'nyaa'."(Maya)

"Please mother. Don't speak about it anymore. It's too embarressing."(Sariina)

She shouts out. After that talk, nobody said anything. After I finished eating I started to leave, when Gray said to me:

"Lucifer, I want to talk to you. Can you come with me?"

"Yeah sure."

I answer him. He gets up from the chair and tells me to follow him. We walk to the garden and I ask him:

"What do you want to talk about?"

"Does Sariina know who you really are?"(Gray)

"What do you mean?"(Lucifer)

"That you are the true demon lord."(Gray)

I try my best not to look surprised. How the fuck does he know? I say to him:

"I'm not the true demon lord. What is the true demon lord at all?. I have heard of demon lord but never about the true demon lord."

"Don't play dumb! I know you are the true demon lord. I will ask again. Does Sariina know who you really are?"(Gray)

"Yes. She knows who I really am. But how did you know that I'm the true demon lord?"

"By your sword. My grandfather got along with the last true demon lord. He often told me about their adventures and he described me about the last true demon lords sword. When I saw your sword I knew you were the true demon lord, because it looks exactly the same, like the sword that was described to me."(Gray)

"I see now. So that's how you figured it out."

"So Sariina knows about it and still loves you?"(Gray)

"Yes. She loves me and I love her."(Lucifer)

"I see. I can tell that you love each other. So, Lucifer, I'm leaving my daughter in your care."(Gray)

"I will take care of her. I promise."

"That topic out of the way, you should know that the hero is your enemy now. I have heard rumors, that some great power got into his hands."(Gray)

"I know that. When I meet the hero I will kill him for betraying me."(Lucifer)

"How did he betray you?"(Gray)

"Sorry, I can't tell you."(Lucifer)

"Okay. I understand. I won't ask any further."(Gray)

With that our talk ends and I go back to Sariina. I go to her room and see her sitting on the bed. She looks exhausted.

"Why are you looking so tired Love?"(Lucifer)

"After you left with father, mother dragged me into the living room and started asking about our relationship and about last night. I didn't want to talk about it and wanted to get away, but she didn't let me. I finally got away and ran to my room. So what did father want to talk about?"(Sariina)

I then tell her what we talked about. After that she says:

"Well then Luc, take care of me."(Sariina)

"Love, it's till morning and everyone is awake. I can take care of you at night."(Lucifer)

"Luc I didn't mean that kind of taking care of me."(Sariina)

I sit down, lift her onto my lap and place my head on her shoulder. I wrap my hands around her waist and say:

"I knew what you meant. I just wanted to tease my cute Love."(Lucifer)

"Don't tease someone who is older than you."(Sariina)

She then turns her head towards me and kisses me. We kiss about a minute. After that I say to her:

"Didn't you want to become an adventurer? So lets go to the guild."

"Okey Luc."

Sha answers me and gets off my lap. I get up too. I put on my coat and scarf and she put her coat on. We then take our equipment and leave the room. We say our goodbyes and leave the mansion.
