As she dried the cat after bathing it:

The cat exclaimed with a series of meows, "You crazy girl, how dare you make a demon king bathe with you? Stop, stop... Girl, where are you touching me? You have no shame," he started moving his body; he was flustered, no one in his entire life had treated him like this.

Ella, unaware that she had brought a demon king home, casually spoke to the cat. "What name should I give you? Let me think. Milo... how does that sound?"

The cat responded with more meows, "I already have a nice name, girl. You don't even realize what you brought home. You will regret keeping me here."

Observing the cat energetically scratching all over the bedsheet, Ella guessed, "I guess you loved your new name. You are such an unusual cat."

She continued, "From tomorrow onwards, I have my summer break starting. So, I will be home. We can spend lots of time together... Milo."

Caressing the cat, she said, "Let's go for dinner; Mom and Dad must be waiting for us to join."

On the way downstairs, she heard her mother say, "Honey, come and eat your dinner."

"Yes, Mom, I am coming," she replied, carrying Milo with her.

Milo, thinking of running away, said, "I need to find my men as soon as possible. I can't stay here like this."(Meow.. Meow... Meow..)

Mother asked Ella if she had brought some cat food on the way, to which she replied, "Yes, I brought some, but I'm uncertain if Milo will love it or not."

Mother, staring at the cat, remarked, "Milo, huh? Nice name. What an unusual cat with red eyes. Our Milo must be some foreign breed; I've never seen such a beautiful cat."

Milo retorted with a meow, "Old hag, I am the most handsome being in this world."

Ella brought the cat food in front of Milo to eat, but he got angry and left to sit in the corner of the room.

The cat expressed its displeasure with a series of meows, saying, "How dare you, human, make me eat this. I am hungry, but I want to avoid eating this." (Meoww.. Meoww... Meow...)

Ella's mother then suggested, "I think Milo doesn't want to eat at the moment. Keep this food in your room. When Milo wants to eat, it can have it."

She also instructed Ella to take Milo to the vet the next day.

Agreeing with her mother, she went upstairs with Milo to her room. Upon realizing that her room was a mess, she cleaned it before retiring to bed with Milo.

Late at night, the cat turned back into the Demon King and regained his powers.

"I've transformed back to my original form. Now, I have to figure out a way to get back to my world, but how?" the Demon King pondered.

The snoring sound of Ella surprised him. "Hey, human, stop making that sound. I can't sleep like this," he said.

A few minutes later, Ella cried out in her sleep, "Save me, save me."

The Demon King watched her, noting, "Now she's started sleep talking. Why is she making weird faces? She's trembling. I can feel dark energy from her."

He could sense dark energy surrounding her. "What is she dreaming about? Since you helped me last time by saving me from that dog, I will help you this time," he said.

He kept his hands above her forehead and used some of his power to enter her mental domain.

"I am in her dream now. It's all dark," he talked to himself.

He heard Ella's voice, "Help… Help… You red-eyed monster. Stay away from me."

The Demon King moved to help her, but there was no one. He continued to watch Ella from the corner, noticing footsteps approaching.

"There is someone... Who is that person? I was right. It's not just a dream. It's something else," he realized.

With red eyes, the newcomer defied the expectation of any ordinary demon. Only a royal member of the demon clan could possess such eyes, he thought to himself.

"Stop! Who are you? Stay away from her," he shouted at the demon approaching Ella.

He wielded his power to summon a luminous orb in the air. As the radiant beam struck the demon's countenance, the Demon King was taken aback.

"How can this be possible? Have you assumed my guise to pursue your prey? You are a Dream Hunter Demon, a skilled entity tracking me within the human world," he queried the demon.

In response, the demon chuckled mockingly, "HAA HAAA. That's quite fascinating. You will indeed recall me, my reincarnated self. Our paths will inevitably cross again... Farewell..."

"What a jest this is... You would be wise not to cross my path again, or I will ensure your swift demise," he retorted with a simmering anger.

With resolve, the Demon King departed from the mental domain as Ella began to awaken.

As she slightly opened her eyes from a slight headache, the Demon King transformed back into the form of a cat.

Pondering to himself, the Demon King questioned, "Is she somehow related to the demon clan? Have I met her before? I am not from this world, so it is unlikely that I have met her previously. Yet, why do I feel this sense of unease upon seeing her, and what was that demon implying?"

"I must consult the old man about her; perhaps he possesses knowledge that I lack. Until then, I must remain here to gather more information.”
