He placed his bag on the desk and looked around since he was the first one to arrive in their classroom. He remembered what happened last night. His mother finally accepted Yuu as her grandfather, meaning that he is his great-grandfather. His classmates arrived one by one and he smiled at them when they greeted him good morning. It was his second day in school but until now, he couldn't absorb everything that was happening around him.

"Good morning, Yuuki-kun." His seatmate greeted him and he smiled at her while greeting her back. Somehow, he was feeling uncomfortable when she was beside him. He also remembered that Hanahime cried when she approached him yesterday.

The official classes started and he focused on everything as much as he could until he saw a familiar figure walking in. A wide smile formed on his lips when he saw his great-grandfather wearing a working suit. He secretly pulled out his phone from his pocket and saw a message notification. When he opened it, it was confirmed that his great-grandfather will be one of his subject teachers for that school year. He put his phone back inside his bag and then, he couldn't help but to feel excited about what the older one would teach.

His eyes widened when the time suddenly stopped. He stood up from his seat and then, Yuu approached him. It was his first time to experience something like that but he felt like it would be one of the powers he should avoid on learning. What more that made him surprised was when his seatmate was not affected by the powers. She stood up and gave them a cold look. Aside from them, she was also one of them.

"I'm right from the start. You are no ordinary human. You're a demon." She said and he clenched his fists tight. He was there to enjoy new things like attending school and making friends but it seemed like there would be a nuisance.

"And you're an angel, Itsumi." He said and a smile formed on her lips. He furrowed his brows and she suddenly hugged him tight, jumping while chuckling softly. He gently pushed her away and gave her a questioning look.

"I'm your aunt. My father is Itsuki. I know you're Aunt Gia's grandson." He deeply sighed at what he just learned. The older one watched them talk and then, he went out of the classroom for a while to see if there are more people like them. So far, it was only Itsumi.

"I know, I fought him before. Why are you even here?" He took his seat once again and she smacked his arm while pouting as she felt like he didn't want to see her around. She also took her seat when Yuu gestured that he will resume the time already.

The day passed by without any more disturbances. He squinted when Itsumi started following him. Other students looked at them when she suddenly hugged his arm. His parents arrived and they were surprised that he was with a girl. Itsumi immediately introduced herself and Yuuki sighed in relief as he doesn't want his parents to think that she will be his future wife. He couldn't even see the disappointment on his mother's face.

"So, you're Itsuki's daughter with another angel. So, you're my cousin." Fuyu said while they were in the car. She noticed that Hanahime was glaring at Itsumi, so she asked her what was wrong. If her daughter could just speak, she would already be throwing tantrums.

"Your family tree is getting more and more complicated." Sho said once they arrived home. She put Hanahime down on the couch and then, when Itsumi tried to carry her, the little one started screaming, wailing her arms as if she was trying to push her away.

"Hanahime, why are you like that to your aunt?" Sho asked as he carried her in his arms. The little one cried and hugged her father. When they were about to go to the playroom, she threw more tantrums and cried harder.

"What's wrong?" He asked her once again and when he felt that something was wrong, he rushed back to the living room, seeing Fuyu and Yuuki struggling from Itsumi's dark tentacles. He materialized one of his black katanas, attacking Itsumi with it.

Fuyu and Yuuki fell on the floor when he cut off the tentacles, gasping for air. They were about to attack the girl when she suddenly fell on the floor and lost consciousness. Yuu was holding a transparent sword with gold highlights since he stabbed her with it. Hanahime slowly stopped from crying and then, she crawled towards her great-grandfather. The older one carried the little one as he put his sword down. They couldn't believe what just happened.

"It was one of the thousand demons that your grandmother summoned. It seems like they are now moving to kill all the people related to your mother." Yuu said to Fuyu. He knows that he has a fault there because it was his wife who summoned them just to have a son and now, they are asking for the payment.

"So, there will be more?" She asked and he nodded. She sighed in frustration. She got Hanahime back in her arms and hugged her gently. Perhaps that was one of the reasons why the little princess was so moody when Itsumi was around. The girl's body started to disappear.

"If you need my help, Hanahime can immediately summon me. She can detect the thousand demons and it will automatically cast a spell on me to teleport here." He added and she looked at the little princess who was already sleeping in her arms.

"For now, I will talk to my wife to ask if she knows how to defeat all the thousand demons." She nodded and then, she gave Hanahime to Sho. When Yuu left, Yuuki hugged his mother. It was his first time to experience something like that even though he already went to a war between the angels and demons before.

"Are you okay?" Fuyu asked her son and the younger one nodded. They don't know what the abilities of each demon are, so it will be much better for them to be prepared. The demons could easily borrow other people's identities, so it means that they should trust no one but only themselves.
