"Miu, Karin's situation is a bit special. The place she lived in before was invaded by monsters, and her family is all gone. Also, she lived in a very remote and backward place, so there are many things Karin doesn't understand. I hope you can help Karin a lot, okay?"
After the two introduced themselves, Takeru quickly fabricated an identity background for Karin.
"Huh? I understand." Hearing Takeru say this, Miu was somewhat surprised but nodded.
Karin, noticing Miu didn't seem hostile toward her, also breathed a sigh of relief.
"Alright, Karin, Miu, you two chat for now. I'm going to clean up first. If there's anything you don't understand, you can ask Miu." Seeing the two, Takeru spoke with a light laugh.
"Mm." Although Miu wanted to stay with Takeru longer, hearing Takeru say this, she couldn't stop him.
Then, Takeru went to the bathroom, quickly filled the tub, took a simple shower, then left.
Outside, Karin was still curiously asking Miu about cars and airplanes, while Miu was teaching Karin how to use the internet.
Compared to other methods, the internet could provide knowledge much faster about most things.
"Alright, Karin, you go wash up too, then get some rest. I'll tidy up the guest room for you now." Looking at Karin, Takeru quickly said.
"Okay." Hearing Takeru's words, Karin nodded quickly. Then Takeru explained hot and cold water, shampoo, and body wash to her in detail.
Karin listened carefully to Takeru's explanations, finally nodding to show she understood.
As for a change of clothes, since Miu's clothes didn't fit Karin, Takeru asked Miu to watch over Karin at home while he went to a mall to buy her a few simple outfits, planning to go shopping for better ones tomorrow.
"Sorry for the trouble." Hearing Takeru had to go buy clothes for her late at night, Karin said apologetically.
"It's fine. Ask Miu if you don't understand anything. I'll be back soon." After another reminder, Takeru quickly headed toward a nearby mall.
Although it was getting dark, many clothing stores were still open. Takeru entered one and directly selected a few outfits for Karin, including underwear...
The store Takeru entered wasn't a luxury brand but a reputable one with good quality and service. So, for three sets of clothes and some underwear, Takeru spent over 100,000 yen.
Takeru paid calmly, then took the bagged clothes from the clerk and left the store under the clerk's envious gaze.
Returning home, only about ten minutes had passed. Karin was still in the bathroom.
Takeru didn't mind, then picked out a set of clothes and have Miu take them in for Karin.
After doing this, Takeru went directly to the living room and began training Senjutsu Chakra.
Perhaps due to his exceptionally high Spirit attribute, Takeru entered a meditative state in less than a minute. As Takeru entered the training state, he soon sensed external Natural Energy continuously flowing into his body, merging with his Physical and Spiritual Energy, slowly forming Senjutsu Chakra and gathering with the previous amount.
However, what surprised Takeru was that the Senjutsu Chakra he trained differed from Naruto's. If Takeru remembered correctly, the ratio for Naruto and others was 1:1:1 for Natural Energy, Physical Energy, and Spiritual Energy.
But for Takeru, the ratio was roughly 3:1:2. Perhaps due to this special ratio, Takeru didn't undergo any physical changes when using it.
Although the Senjutsu Chakra Extraction Technique was still at the beginner level, and Takeru's extraction speed was somewhat slow, he could still clearly sense the Senjutsu Chakra continuously increasing.
He didn't know how long passed before Takeru was awakened by Miu and Karin's calls.
"What's wrong?" Awakening, Takeru felt refreshed and looked at the two, puzzled.
"Brother, it's already midnight. Time to rest." Hearing Takeru's question, Miu puffed her cheeks and spoke.
"Is that so? Alright." Hearing Miu's words, Takeru realized. Immersed in training, he hadn't noticed time passing.
The feeling of clearly sensing himself grow stronger was so good that Takeru ignored the passage of time outside.
But since awakened, Takeru bid goodnight to Karin, then went back to his room with Miu.
Lying back in bed, Takeru soon re-entered the training state. Seeing Takeru quickly enter meditation, Miu felt somewhat discouraged. Although she had urgent questions for Takeru, seeing his state, she didn't dare disturb him.
Takeru, immersed in meditation, was unaware of Miu's situation. However, he could feel the amount of Senjutsu Chakra in his body growing larger as time passed.
The next morning, when Miu woke up, she found Takeru, who usually would have woken up early to prepare breakfast, still sleeping. She was stunned.
"Brother!" Thinking this, Miu gently woke Takeru.
As Miu called, Takeru quickly exited the training state, though he was slightly dazed at first.
"Hmm, Miu, you're awake." After a dozen seconds, Takeru reacted and looked at Miu in surprise.
"Yes, brother. It's already 8:30 a.m." Hearing Takeru's words, Miu showed him her phone, indicating it was late.
"I see. Wait a moment, I'll prepare breakfast for you." Hearing her words, Takeru nodded understandingly. As he just started training Senjutsu Chakra, he needed to focus wholeheartedly to improve efficiency. Later, when proficient, it wouldn't be so troublesome.
One night of training had increased Takeru's Chakra amount to three times the initial quantity.
The growth speed somewhat exceeded Takeru's expectations. He felt it might be related to his base attributes, the previously consumed aptitude potion, and lastly, the Senju bloodline and Sharingan might also boost Senjutsu Chakra.
After sensing his condition, Takeru prepared to make breakfast for Miu.
"Not that, brother! Are you okay?" However, as Takeru was about to get up, Miu directly grabbed him, speaking worriedly.
"Don't worry. Your brother is the strongest, and nothing's wrong. It's just that from today, I'm training a special technique and need to adapt to it." Hearing Miu's words and noticing the concern in her eyes, Takeru understood her worry and patted her head reassuringly.
"That's good then." Hearing Takeru's words, Miu relaxed and nodded.
When Takeru came out, he noticed Karin in the kitchen, flustered. Although Karin wanted to prepare breakfast for Takeru, she didn't know how to use the gas stove or microwave and was afraid of damaging them, so she was anxious.
"Let me handle it. I'll show you how to use these things later." Noticing Karin's situation, Takeru said with a light laugh.
Then, Takeru quickly washed up and went to the kitchen.
"Karin, you turn this on like this." Noticing Karin's curious gaze, Takeru demonstrated turning on the gas stove. Seeing the sudden flame, Karin was very curious.
"And remember to turn off the gas stove after use. Also, here are precautions when using the microwave." Looking at Karin, Takeru quickly explained carefully.
For breakfast, Takeru took out a Spider Eagle's Egg, baked some bread, pan-fried some steak, and boiled hot milk for three. A hearty breakfast was ready.
"Awesome, we get the giant egg again!" Noticing the Spider Eagle's Egg, Miu said happily.
Karin, while enjoying breakfast, pondered the knowledge she just learned.
After the meal, Karin proactively took on dishwashing. Takeru demonstrated once.
After cleaning up, Takeru noticed constant messages in the group chat. Everyone was discussing where to meet, and several were repeatedly @-mentioning Takeru.
