Yuuki looked at his phone and saw it was Elsa. He opened the call by saying, "What's wrong Elsa?"

"Where are you, Yuuki?" Elsa asked.

"I am in my big sister's house, I need to take care of my nieces," Yuuki said.

"Hmm, when are you going to come back?" Elsa asked.

"Maybe tomorrow, I don't know yet, I will call you later," Yuuki said.

"Ok, then, I will continue my work," Elsa sounded very spirited.

"Hey," Yuuki said.

"Hmm?" Elsa said.

"Nothing, I was just thinking that I wanted to hear your voice," Yuuki said.

Elsa didn't answer him for a while but she was blushing very hard, "I-I closed the phone! The supermarket is quite busy!" She closed the phone hurriedly and took a deep breath. She was beyond happy and walked in a very excited manner. Her co-worker was stupified when she looked at her.

"Is there something happy happening?"

Elsa gave her a smile and said, "Nothing."

---

Yuuki thought Elsa was very cute. He placed back his phone and asked his nieces, "Sorry, what did you ask earlier?"

Miu and Sora opened their mouths wide when they heard that conversation. They thought that must be his girlfriend since they heard it was a woman's voice and he talked very intimately with her.

"Oi-tan, who is that?" Hina asked curiously.

"That's my friend," Yuuki said.

"Friend? Not a girlfriend?" Miu asked.

Yuuki shook his head and said, "No, only friend, also Hina, your mouth is messy." He took a tissue and wiped her mouth.

Hina looked curiously at Miu, "What is a girlfriend?"

Miu and Sora were too shy to answer this question.

Hina became even more curious and asked him, "Oi-tan, what is a girlfriend?"

"Well, girlfriend is..."

Miu and Sora were shocked when they saw he wanted to answer this question.

"Un-."

"Girlfriend is a female friend," Yuuki said.

Miu and Sora sighed in relief when they heard his answer.

Hina nodded and continued to eat. She wasn't that interested in this female friend. But it was different for both Miu and Sora. They were very curious about this woman who was close to their uncle.

Yuuki helped Hina to eat since this little girl was very clumsy to eat with a spoon.

"Aaaah," Hina opened her mouth.

"Don't forget to chew it 30 times," Yuuki said.

Hina nodded and chewed the food for 30 times.

"Uncle, how is the life of a hunter?" Miu asked.

"Hmm, it is quite good," Yuuki said.

"Isn't it dangerous to fight a monster?" Miu asked again.

"Monster!!" Hina suddenly stood up.

"Don't stand up suddenly what if you fall," Yuuki was getting scared of this little niece of his.

"Oi-tan, did you fight a monster?" Hina asked.

"Yes, I fought them," Yuuki said.

"Hmm, how did you fight it?" Sora was also quite curious.

"Hmm, I hit it until they lost," Yuuki said. He didn't really want to tell them about the life of a hunter.

"Eeeeh?" Miu seemed unsatisfied with his answer.

"You're still a kid, don't think too much about it," Yuuki said.

"I am not a kid!!" Both Sora and Miu said at the same time. They really thought their uncle couldn't see their charms and treated them as a kid.

"What does your female friend look like?" Miu asked. and Sora was also curious.

"Hmm, she is beautiful," Yuuki said.

They were shocked and became even more curious.

"Can you show us?" Miu asked.

Yuuki took his phone and showed them. Elsa liked to take a picture of both of them whenever they were together using his phone.

Miu and Sora took his phone and saw a beautiful woman who was laughing beside him. Their expression became ugly and knew this was their enemies.

"Hina wants to see it too!" Hina looked at the picture of Elsa and said, "Wow, she is beautiful and her milk is like a mama."

Yuuki wasn't sure how to react when he heard her say, "Finish the food, okay?"

"Okay!" Hina said, but both Miu and Sora didn't answer him.

"Is the food not suitable for you?" Yuuki asked.

"N-No, I didn't expect my uncle to have such a beautiful female friend," Miu said.

"Well, don't think too much, it is normal for an adult to have a friend or two," Yuuki said.

"But Onee-chan will be disappointed since my uncle has a girlfriend," Miu said with a sigh.

"MIU!!!" Sora shouted.

"Eeeeh! But Onee-chan took a bath twice when you heard him will come to the house, which is why he ended up seeing you in underwear," Miu said with a naughty smile.

"MIU!!" Sora was very embarrassed right now.

"Hahaha, you're embarrassed how cute!!" Miu teased her and ran.

"Hey, wait!" Sora followed her and stopped. She looked at him and said, "That isn't why."

"Hmm?" Yuuki looked at her.

"I was cleaning and started sweating, so I got all dirty, so that's why I...." looked very flustered and added, "That's why I took a shower again, that's all there was it!" She said and ran.

Yuuki started to think that girl in puberty was quite difficult. He was thinking over until Hina pulled his shirt.

"Oi-tan, let's play a game," Hina said.

"Sure," Yuuki decided to not think about it.

---

"Ah, Hina-chan is good," Yuuki said. He lost deliberately on her since she was a kid. He wouldn't even be happy to win against her in the game.

"Hehehe," Hina was happy that she won against him.

"Moo, uncle is weak!" Miu said.

"Give me, I will show you how to play a game!" Sora said.

Yuuki saw both of them come back with a very bossy tone. He smiled at them and said, "Well, let me show you my skill."

Miu and Sora had a bad forbearing when they saw his smile.

---

Miu and Sora were shocked when they saw they had lost several times.

"Wow! Oi-tan is very good!" Hina was amazed.

"But Hina is even more amazing since Hina can beat me," Yuuki said.

"Yay! Hina is more powerful than Nee-chan!!" Hina looked very happy.

Miu and Sora couldn't say anything to her since Hina looked very happy.

They played for hours until they fell asleep together.

Yuuki sighed when he saw they were sleeping on his arms. He couldn't move and decided to sleep together.

---

"We're home!!" Yuri came home together with her husband.

"Is your little brother here?" Shingo asked.

"Yes, let's check the living room," Yuri said.

Both of them were walking together and saw their daughters and Yuuki were sleeping very close there.

"My friends have already become very close," Yuri looked happy.

"Hmm, as I thought he looked like a hunter," Shingo observed him.

"What are you talking about, let's wake them up!" Yuri said to him.
