~A few days later~
As they were standing outside, the Fifth Unit were now standing before Nagisa. As the boy was standing right in front of them, they noticed how his entire presence changed. Right now, an air of seriousness was present. Before they knew it, Nagisa was already in front of Saki as he punched the girl in the gut.

Suddenly, Nagisa found himself trapped within a tornado as Yakumo used her ability. Meanwhile, as she managed to land on her feet, Saki suddenly turned her right arm into a sub machine gun as she fired several rounds at Nagisa. However, both Yakumo and Saki's eyes widen in shock with what they saw.

Nagisa began to manipulate the air of the tornado he was trapped in with his hands as he released razor-sharp whirlwind pressures to break out of his cage and slice the bullets that were heading towards him. Before she realized it, Saki suddenly saw Nagisa front of her as he slammed his right fist into her stomach as the girl coughed violently.

Suddenly the boy turned around as he was swiftly blocking Yakumo's fists. However, the chief smiled as her right fist was caught by Nagisa. Suddenly Yakumo did the same hand gesture that Nagisa did earlier, however, she managed to send Nagisa flying backwards as her use of Bomb's martial arts had far more power to it.

"Perfect. Fist of Whirling Wind Slashing Steel already involved the manipulation of the air. The reason she has more power when using it is due to the fact she can generate the wind needed and alter the power of it as much as she wishes. As for Saki......"

As Nagisa lands on his feet, he noticed how Yakumo used her wind to send Saki flying towards him at high speed. The moment she got close, she turned both of her arms into guns and fired them at the boy. Just as Nagisa used Fist of Whirling Wind Slashing Steel to cut some of the bullets, he noticed how the girl swiftly shifted her arms from guns back to her hands as she quickly landed a punch to Nagisa's liver, only for the boy to land a kick to her chin at the same moment.

"......her speed of transforming her body into weapons and back to normal has increased. By helping her with her combat ability without weapons, she can mix up her attacks at any given moment. Good, they made great progress."

"That's enough for now. Everyone take five."

As soon as Nagisa said this, both Yakumo and Saki fell to their knees. Truth be told, it took all they had just for them to apply the advice that Nagisa gave to them. While everyone was resting, Kaiko walked over to the group with bottles of water.

"Here you go everyone, don't overdo it."

"Thanks, Kaiko-chan

"...."

"Thanks, Kaiko-san."

"It was no problem. Also, i'm sorry I couldn't be of much help, Tomioka-san."

A sad smile formed on Nagisa's face. During their first day of training, Kaiko used her ability to heal everyone from their injuries. However, when it was used on Nagisa, his blood was still pitch black. Not only that, his mental state was still the same. It seemed like Kaiko wasn't able to help heal him mentally.

"It's okay, Kaiko-san, it was worth a shot."

"Honestly, you should loosen up a bit, Nana-chan."

"................"

"What the hell did Yakumo-san just call me?"

"Well, it seems like you have a lot on your mind, so your sexy big sis Yakumo will help you out."

"Oh dear god........."

"You should just let loose, Nana-chan. You may be in the corps for a reason, but that shouldn't be the only thing on your mind. Life would be pretty boring if you only thought about work. So be like me, MAKE YOUR HAREM AND LIVE YOUR BEST LIFE."

Silence. All Yakumo was met with was silence. Nagisa appreciated her advice, hell, part of it was even helpful. Though as soon as he heard the last part, he couldn't help but just stare at the young woman like she was a weird creature. Seeing this, Yakumo began to smile at the boy.

"Come on, Nana-chan. I'll let both you and Yuuki join my harem. Everyone will be loved."

"Get away from me!!!!"

As Yakumo lunged to hug Nagisa, the boy was running away as fast as he could. While Yakumo was flying around to catch Nagisa, Kaiko was seen laughing at the scene while Saki had a small smile forming on her face. Things were always lively here, but for some reason, today felt even more fun than usual.

"I guess letting my guard down at least while i'm with the Anti-Demon Corps isn't so bad."

~Meanwhile~
As she was seen at a desk, Ren was looking at which unit to send Nagisa too next. This was brought to a halt as she heard someone walking into the room. When she turned around, she saw Gun standing in the doorway as he had a smirk on his face.

"My, my. To think you would go this far for a guy you don't want to lose to."

"What are you getting at, Gun?"

"Simple, you noticed how after the incident, Nagisa's mental state was unstable. To keep him from focusing on how negatively his mental state was getting, you're sending him to other units to help ease his mind by using training as an excuse."

Ren pouted when she heard Gun's thought. He wasn't wrong, she was doing this to put Nagisa in an easy state of mind. Not only for his sake, but for the sake of the whole corps. If he were to be unstable and he suddenly went on a rampage like that again, who knows how much damage he could cause. It was best to help him stay calm mentally.

"So Ren, what do you plan on doing?"

"Well. I already have Bell training with the Seventh Unit currently. The next stop for Nagisa will be the Ninth Unit due to the request by Azuma Tobera. After that, we will allow them to train in Shangri-La."

"I see. So you-"

"Yes. Gun Park, you will help train Nagisa to master Ultra Instinct."

"I had a feeling you'd say that. I also made some adjustments and called someone. You want Nagisa to keep his cool that way he doesn't rampage. Plus I noticed how sometimes his movements were identical to this man. Once he arrives, i'll let him know about the situation."

~????~
"So this is Japan. I must say, this is quite a pretty place."

A single man was seen walking out of the airport as he took off his sunglasses. To say he was handsome would be an understatement. He was a very attractive man with pink hair and dark eyes. He also had pale skin and a slim body figure. As he began to walk to the place he agreed to meet the person who requested him, he began to think to himself.

"Not just Goo, but even drawing Gun's attention as well. I wonder what kind of man you are, Tomioka Nagisa."
