The next day, Kai and Kaya returned to the cabin in the forest. During their trip, Kaya tried to understand why they had to go back urgently but all Kai said was that it was a weird occurrence.
Now, whether it was a dangerous matter or not, Kaya couldn't say. But, she at least knew that it was important enough for them to quickly take the first plane back.
Now, they were standing in front of the cabin's door. Kai's eyes scanned the area to check if there were any abnormalities. However, he noticed nothing of importance so he stepped toward the cabin's entrance and opened the door.
What welcomed him was the sight of a chaotic mess. Whether it was the furniture, the tables, the beds, or even the kitchen, they all looked as if they were hit by a violent storm.
"What the hell happened here?" Kaya murmured as she kicked a broken vase to the side and moved inside. "Did someone raid this place?"
"Eva," Kai called for the girl.
"I'm here…" Luckily, a reply came to him so he walked toward the source of the sound.
Inside Eva's room, he found her crouched on the ground. Her room was also a huge mess. She was picking up broken glass.
When she saw Kai, she jumped up and rushed toward him. "I missed you so much, Kai!" She said as she hugged him tightly.
The latter held her from falling as he kept looking around the place. "What happened here?" He asked.
"I… don't know. I came back yesterday and I found the place in this state."
Kai's eyes squinted as he put Eva down and walked outside. His eyes scanned the area again before he asked a question.
"Where is Miyu?"
The two girls looked at each other confusedly before they shook their heads. So, Kai spread his senses to cover the whole forest.
It didn't take him even a second to find what he was looking for. So, he left the cabin and walked around the place to the interior part where the pool was. Kaya and Eva followed him.
When the trio reached their destination, they were shocked by a sight they never expected. Kaya had to even scratch her eyes in case she was hallucinating.
Right there, sprawled on the ground, clearly asleep was a gigantic cat three times the size of an average human male. Her distinct midnight black fur made her quite easy to distinguish from other cats.
"Miyu…" Kai murmured her name with a confused expression. What in the hell happened to the cat at the time he was not here?
When the cat heard her name being called, her beautiful, big -now even bigger- eyes looked up. Immediately, her face turned from drowsy to excited in a moment.
"Meow!!!" She meowed loudly.
However, the sound was so loud that it rumbled in the trio's ears. The trees rustled and even birds flew from the branches, thinking there was an earthquake that hit the place.
Then, the cat ran toward Kai and jumped him.
*BOOOM*
Kai found himself getting crushed by the giant cat as she rested her giant head on his stomach and started licking his face.
Her tongue was big enough to cover his whole face.
"Wait…" Kai pushed her tongue away and looked at the excited cat. "What happened to you, Miyu?"
"Meow!!" The cat responded excitedly as she looked back at the volcano.
It didn't take Kai long to link things together before he came to the conclusion. "Is it that pure Origin you absorbed?"
"Meow!!" The cat responded enthusiastically.
"She grew in size because she absorbed Origin? What kind of magic is this?" Kaya sighed as she looked at the cute, albeit overly big animal. Even with her intimidating size, Miyu was still extremely cute.
"Woah, Miyu is amazing! I've never heard of Origin affecting the anatomy of a creature no matter what it is." Eva exclaimed.
"Meow!!" Miyu nodded her head before she stood up, letting Kai free from her giant hug.
"She's not a cat. Maybe a creature that looks like a cat, but not a cat. So, we can't really say that Origin would affect her just like how it would affect normal people." Kai replied.
"Her aura also increased tens of folds in strength and purity. It's almost half my power now." Kaya commented with a thoughtful look.
"She still hasn't reached her peak yet." Kai approached the cat and touched her forehead. The latter allowed him silently and closed her eyes.
"Her Origin Veins are still not full. She can grow even stronger than this."
"Meow!" Miyu jumped excitedly at his words. Each jump she made shook the place.
"What should we do about her, now? We can't let her inside the house or she will make a mess like the one we just found."
"Meow…" Miyu's ears fell down as she sat with a sad look on her face.
"... We can build a house her size where she can sleep," Kai said.
"Meow!"
"Seriously? How big would that house be?" Kaya sighed.
"Grrr…" Miyu glared at Kaya with hostile eyes as she protruded her fangs out.
"What? Look at your size, Miyu. You're almost bigger than the cabin." Kaya said.
"Meow!!"
"Oh, yeah? Like you meowing loudly would help this situation."
"Hey, old hag. She's just a cute cat. Be nice to her."
"You're really too naive, Kiddo. That cat isn't even a cat! She's as sentient as all of us here!"
"Meow!! Meow!! Meow!!" Miyu meowed even louder as if she protesting. Then, she made a very cute face as she started rolling on the ground just like a normal cat would.
"See? Who is the big, cute cat? Yes, it's you~" Eva approached her and started rubbing her stomach. The latter purred as she let Eva massage her. The sight was as ridiculous as it sounded.
"God have mercy on my soul." Kaya facepalmed as she looked toward Kai. "Should we take a day to help you build it?"
"No need. I will build the house myself while you two train. We already lost one week because of the recent events. We can't waste any more time. Eva, let's go." Kai interjected. Building a house for Miyu won't be a problem for him. Now, their focus should be on training and nothing else.
Kai wasn't even sure if they could actually make the schedule he planned before the start of this training trip.
"Ok~ Now, be a good girl and don't enter the house, Miyu. Ok?"
"Meow!!"

Then, for the next few days, Kai kept training Kaya and Eva with his light clones relentlessly. He made them fight for hours and hours without stopping. The intensity only kept on increasing as when Kaya and Eva were close to reaching an epiphany, the difficulty would increase and the challenge would become even tougher.
However, Kai was noticing the change they were having. In the first days, they were only able to reduce the size of their auras to the general area where the attack would be. But, slowly but surely they were able to start manipulating the Origin with more mastery.
But, that improvement came with pain and suffering that pushed the two girls beyond the edge. The sheer amount of hits they sustained was ridiculous. Was it not for the fact that Kai healed them after each training session, the two would've eventually succumbed to injuries.
At the same time, Miyu continued to go to the volcano each day to absorb Origin. Her size didn't increase any further but her strength did, exponentially so.
