Request accepted. 

The host will move to hell difficulty level dungeon if he's able to complete the level 50 dungeon. ]

Ting!

[You have successfully made a pact with the hidden boss 'Detiria' 

Detiria will follow your command from now on.]

"I didn't even touch it yet, then how did I make a pact with it?"

"Because you feed me Dii"

Nikita's eyes nearly reached his forehead by hearing it talk like a human. 

"You can talk?"

He was too surprised to see human-like behaviour from a monster. 

"Yes, every high-level monster can talk. You are also a monster, right? You're a high black fang Dii."

   I guess it can't sense the human soul inside me. So I will just go along the flow of this conversation.

"Oh. Yes."

"Tell me Dii, what is your name Dii? You don't look like you're a normal monster born from normal parents. Are you born from the boss monsters?"

"I don't have a name. You can see my status right? So what's the point of asking?"

"Sorry Dii, I was curious about my master."

   It looks so weak. Did something happen to her?

"Are you sick or hurt somewhere? You look sick."

"Don't worry Dii. I will be okay Dii"

I guess she doesn't have any intention of telling me. But she's trembling like a vibrator machine. I guess I have to do something.

"You can tell me. Since I'm your master now. I have a responsibility to take care of you. So, speak to me when you're feeling comfortable. And take this. It's cold in this part of the dungeon. Sleep near the flame. It will keep you warm."

    She's not telling me at all. But I can feel all of its emotions. It's been abused by something really horrible for years and then it was abandoned. 

Why do I feel like I'm seeing the spitting image of myself on it? 

Tsk! Let's go back to sleep.

…

Next day…

I was barely able to sleep because of its noisy imaginations. Was that monster afraid that I would be like her previous master? 

"Oi, come here."

"Don't hurt me Dii!!!!!"

"Tsk!! Come here! I'm not going to hurt you!!!"

"Waaaaaa!!!! Wa?"

Nikita was holding it upside down to check if something was wrong with its body. 

 "Is this a new way of torturing me Diii?"

"Calm down. I'm not going to torture you. I'm just checking if your body is alright or not. You were shaking the whole night and didn't get a chance to sleep."

Ting!

[Detiria's loyalty towards you has increased to 2%]

Her body is alright, but one of her legs is gravely injured. But how can I heal it?

System. What level is this monster?

Ting!

[Detiria is level 175.]

If it's this powerful, then why isn't it healing?

[Detiria has leech inside its body.]

"What did you eat these days? Your body has parasites inside"

"What's a parasite Dii?"

"It's a small-looking monster eating you alive from your belly. It has to be taken out or your fluffy body will die soon."

Nikita poked his finger on its fluffy belly to indicate it.

"Dii will die diii????"

"Yes. As your master, I want to help you. Since you already know about my level, I want you to give me a name in exchange. It's a good deal right?"

"Hm. But can I trust you? Because an owner can kill a familiar no matter how strong it is Dii!"

"I know, I can level up a lot if I kill you. So why did you choose me as your master?"

"Because… um. Because.. you were eating something delicious?"

"I'll pretend that I heard nothing. I will save you, so think about a name."

"How do you know only a high-level monster can name a lower-level monster?"

"It's just a feeling. If we stay alive, I promise that I will give you a name when I'm stronger than you."

"Then I will wait for the day Dii! We will name each other when you're stronger than me Dii!"

I'm feeling better after talking with someone. It's been years since I saw humans. This thing talking in front of me isn't a human. But I need to be satisfied with what I have. At least we are having a conversation. 

I should be grateful.

"Dii, I want to know your story Dii!! You're nothing like my previous masters Dii!"

"Hahaha! You're so excited to hear my story. Okay, I will tell you while I'm killing those parasites inside your body."

"Okay Dii!!!"

[Skill: Life leech : S, is activated. 

7 links have been established between you and parasites of the familier's body.

Do you want to eat those parasites inside Detiria's body ?]

"Yes."

[Command accepted.]

Those parasites inside her body are stronger than me. Thank goodness that I didn't eat anything from this dungeon without cooking it. Or my body could have those parasites.

Both of them talked about monsters and dungeons. It was the fluffy monster who talked the most because Nikita was curious about the hidden parts of the dungeon.

And he found out so many things about his whereabouts.

The place he was staying was called the Roxilus dungeon with 1000 floors. It was isolated from the real world because of the demon lord who ruled this place. He is the strongest ruler of the dungeon. So strong that the demon god is also scared of him. 

But Nikita wasn't in a situation where he could ask his familiar about the summoned heroes. Because it should be kept secret from the intelligent monsters. Because they are connected to the demon lord when they are inside the dungeon.

I should keep this a secret for now. And I don't think I'm obligated to tell him either. I'm his master, so he should keep his mouth shut.

I bet the system is angry because I'm getting free information from a monster. But I have to move according to the rules. That 6 horn devil has a seal on the heart that can kill me. I have to level up quietly and become more powerful than him. 

Looks like I have to forget about going outside for a while. The system wants me to die anyway by putting me into difficult situations out of nowhere. This system wants me to stay here for a long time and level up.

I guess the system is plotting something weird again behind my back.

[...]

   My gut feelings are never wrong.

"Let's go. We will kill some ice wolves and eat fried meat with apple slices."

"What's that Dii?"

"You will know when you eat it."
