Kai returned to the restaurant with Amber. They immediately went to the second floor and entered his room.

Why were they in Kai's room? It was because Kai wanted Amber to teach him how to replenish his Spirit Power.

From what the Phoenix had said, he had so much difficulty controlling the fire and couldn't make any big and flashy moves because his Spirit Power was almost depleted. It was only around 20% of his full capacity.

Not to mention, the reckless move earlier cost him more of his remaining Spirit Power.

Hence, an immediate refill of his Spirit Power was needed. Indeed, he felt somewhat lethargic after fighting Malice. Turned out it was because his Spirit Power needed to be replenished.historical

Sitting on the bed facing Amber, who sat in the same position, Kai listened to her explanation quietly.

"The special constitution of your body allowed you to contract with a Mythical Beast such as myself and to replenish your Spirit Power just by simple breathing. But that will take too long. You will need a whole week to fill your Spirit Power just by breathing." She explained, raising her index finger.

"So, a technique to replenish your Spirit Power using the Nature power is needed. I will teach you how to do it now, so close your eyes."

"Alright." He replied and followed her instruction. As soon as she closed his eyes, he felt a touch on his shoulders. They were Amber's hands.

"Relax. Take a deep breath when I push your shoulders down. Hold it until I release the tension. Feel my hand closely, understand?"

"Yeah." He nodded. The instruction was simple enough for him to follow.

Surely enough, he felt his shoulders pressed down by Amber. After that, he took a deep breath and held it in until her hand released the tension. Once he didn't feel his shoulders being pushed down, he released the breath he had been holding.

His body somehow felt lighter as some warm feeling entered his body. It wasn't really apparent at first. It could also just be his imagination. But once he repeated it a few times, he understood there was a rhythm, and his body felt a lot lighter than before.

The warm energy that entered his body settled around his stomach and heart area. After understanding the rhythm, he didn't even need Amber's help anymore and concentrated on refilling his Spirit Power.

Unknown to him, Amber was fairly surprised. She looked at him with wide eyes and a happy smile.

'He's able to take in the Nature power and turn it into his Spirit Power in just a few minutes.'

The person she made a contract with was unusual. She knew about it from the start. She kept watching light dots entering Kai's body with a smile.

It was the first time she felt something like wanting to stay with someone. She was a Phoenix, a Mythical Beast of great power and long life. She couldn't even be killed when she was killed.

The people who had targeted her before had some misunderstanding that they could touch her even when she was careless. Still, she would be killed and forced to slumber if Kai didn't help her that night.

She was happy. For the first time, a Human had helped her. So she wanted to share a little bit of her power. Who knew that the human would take all her power and make a forced contract with her?

Usually, that would be something unsightly, giving her imperfection. Giving her a weakness. However, she didn't mind. If it was Kai, she wouldn't mind having a contract with him.

'I want to stay with him forever.'

That was Amber's dear wish. Her carelessness caused two Slayers to come to attack Kai. One was right after they made a contract, and one was a day after. Tonight too.

Because she absorbed too much Spirit Power at a fast speed without purifying it, a Malice was born in the area near them.

While thanks to that Kai managed to encounter one of the Supernatural disasters and gained a precious experience, she needed to be careful in the future.

Or that was what she thought as she planned to teach Kai about everything, including how to control her Phoenix fire better. His learning speed broke her expectations.

'He will be proficient in handling my Phoenix fire tomorrow if he can already do something like that with just a little Spirit Power.' She thought, remembering his fight against Malice earlier.

Without any fear, he closed his distance with Malice and let the Phoenix fire go loose, creating a small fire tornado that engulfed Malice and burned it to nothingness.

'As expected from Kai!' She exclaimed happily with a bright smile.

"Fuu.." When Kai finished replenishing his Spirit Power, he opened his eyes and noticed a pair of golden eyes staring at him. "I am done, Amber." He said.

"Good job, Kai. Also, good morning." She greeted cheerfully while Kai was confused.

"Good morning?"

"Yes. Good morning, Kai." She repeated.

Still confused, Kai turned to the window on the side and noticed sunlight seeped past the curtain of his window, lighting the room with morning light.

"What the–" He was about to curse but kept it to himself. It had been a long time since he cursed and actually managed to stop. Still, this situation was ridiculous. "How could this.."

"..happen?" Amber finished his sentence, making him turn to her again. "This is normal, Kai. For your first time, you will definitely really tell the time and meditate until you fully replenish your Spirit Power." She continued.

"This is normal?" He asked once again, turning to the clock on the wall. It was 6 AM already, two hours late, when he usually woke up and bought groceries for the restaurant.

"Shit!" He rose from the bed and quickly went to the closet, taking a hoodie and wearing it.

"Kai, what's wrong?" Amber asked curiously.

"Grocery! I need to be fast, or we won't be able to prepare breakfast on time."

"Oh, that? I have already bought it. Right now, grandpa is in the kitchen to turn it into a dish."

"Huh? Really?" He stopped and turned to Amber.

"Yes. I knew you wouldn't be able to wake up in time, so I asked grandpa Marcus if I could do the grocery this morning as thanks for giving me the waitress job. He happily accepted and made a list for me, saying that I was a great help."

He was relieved. He thought he would need to close the restaurant for the morning because he was late. "I-I see. Thanks, Amber. You're a great help."

"You're welcome, Kai." She replied with a smile. "Ready for a new day, then?"

"Yeah."
