Flashback During School
Naruto came to his class and smelled an unfamiliar presence. He went in and sat in his seat. Soon, the bell rang and their first-year Homeroom teacher, Mr Sosoke came.
"Good morning, students. How were your summer?" He asked cheerfully and everyone started answering.
He was given class 2-B instead of 2-A as he was in 1-A last year. He didn't give it much thought and sat calmly, listening to his classmates recall their summer.
"You enjoyed it, I see. Well students, from today, you will be getting a new homeroom teacher. Please welcome her," said Sosoke and a young woman walked in.
She is a beautiful young woman with long, straight silver hair and aqua-coloured eyes who appears to be young. Maybe 18 or 19 if Naruto had to guess. She wore a simple purple business suit and skirt.
All of the class including Naruto kept quiet as their new homeroom teacher came in, shocked by her appearance.
"Please introduce yourself, Miss," said Sosoke and she took a chalk and wrote her name on the board in Japanese.
"My name is Rossweisse. I will be teaching your Homeroom teacher and teaching Civics. I'll be under your care during my stay in Japan. Nice to meet you all." She said and bowed at the end. Everyone was astonished at her perfect Japanese.
Naruto knew from the moment she entered that something was wrong with her as he could smell her magic in waves. It was different from his friends as it has a holy tint to it.
'A holy magic-user? Why does her magic have a unique flavour?' He thought in confusion. He idly thought how she and Grayfia had similar hair colours.
All his thoughts were squashed when her aqua eyes turned to him. "Uzumaki-san, can you tell me what is Japan's government structure?" She asked in annoyance as at some point, she started teaching.
As Sosoke left the class in her hands, she started with introductions and Naruto's was done on autopilot. It seems she noticed his lack of attention.
"Ours is a Unitary Parliamentary Constitutional Monarchy," said Naruto and he saw her eyes widen, but she changed it and asked him to sit but had a displeased expression. She continued her class and the day passed.
Flashback End
As he sat relaxed, Roygun and Kazehana walked in their nurse attire. Naruto must admit, they are very tempting in those outfits.
Naruto can't understand whether the outfit is like that or they are doing this to tempt him. But he had other plans for them and so he focused on it.
"I am waiting for you two. Change into your battle gear, we are going to spar," said Naruto, sipping tea that Reni bought for him. They nodded in joy and went to change.
After 10 minutes in the basement. Naruto was waiting when he saw Kana and Roygun walk in their battle attire.
"Damn, are they doing this on purpose?" He asked his lovely Bishop.
"Maybe? They are ready," she suggested and Naruto nodded in understanding.
"You look badass." He complimented when they walked in. Kana and Roygun smiled widely after hearing that.
"We are going to spar and all out. No holding back you two. I think I will get one more piece soon," he added.
"It may be 2 as well," he said looking at Roygun. She understood and nodded in determination.
"Reni-chan will be our proctor for this," said Naruto and Reni stepped forward.
With a snap of his finger, their location changed into a large wasteland that spread as far as the eye could see.
"Oh my, I didn't think we will spar here of all places," said Roygun. She instantly knew where they were the moment she noticed the shift in the sky. It was her home after all. The Underworld.
"Of course, I don't want to damage our basement," said Naruto and they all changed into their respective battle stances and Reni took the ground in the middle.
"Begin," she said, chopping invisible air. Roygun and Kazehana attacked Naruto without thought and they fell into a smooth hand to hand combat.
They punched, slashed, kicked and they did everything in perfect sync as if dancing. Naruto noticed it and smiled at them widely, encouraging them to go further.
Taking this as their cue, they started using their magics, Wind in case of Kana and Crack in case of Roygun.
Roygun had managed to master her Clan Trait to its previous mastery and went a step ahead by mastering its control and applying it across her body.
"Crack Armour," she said and a purplish liquid filled her body, covering her completely. Naruto can see the black emptiness in the liquid.
'Wow, is it the Dimensional Gap? Does her ability directly send someone into the large emptiness?' He thought in awe.
Kana on the other hand pumped wind through her body and spread it across her body much like Roygun, however, her wind formed a loose armour, going a few inches above her body, increasing her damage area.
"I must admit, your strength improvement was astounding. Let me add my variety for you," said Naruto.
"Amaterasu," as his eyes changed into his Mangekyou. Black flames started to spread across his body, vaporising anything and everything they were coming into contact with.
