[No One Pov]

After the destruction of Atlas and their military structure, Union has lost their military support, many students of Union were sent to the ruins of Atlas to find any to all survivors, which was incredibly small, Like in the 200s.

The destruction of Atlas has shocked the female heroine society, making it start to crack slowly and extending to other problems, the grimms has made the ruins of Atlas as a nesting ground for them and the White Fangs are advancing and attacking more often due to the Non-Atlas presence.

Union Academy on the other hand were furious, because they knew that the men were responsible for the destruction of Atlas, General Ironwood, Winter and Weiss Schnee were the last survivors of Atlas with a handful of soldiers that lost the will to fight now.

The loud family were completely angry that Y/n destroyed Atlas and threatened to destroy Union next if they tried to get him again. They want to make Y/n pay for the crimes that Union has placed against him, but he wasn't going to go easy on them or any female that'll try to encounter him.

Right now, the headmasters are having a meeting with General Ironwood, trying to find a way to capture Y/n.

Ozpina: as you all know, Y/n and the males of the land of males were completely responsible for the destruction of Atlas and other military superiority.

Ironwood: we need to take action as he just declared war against us, we have allies around the world to support us!

Sirzechs: I know Ironwood, but even if we do ask for reinforcements, we have no idea when and how Y/n is going to attack us.

Tsunade: I agree with Sirzechs, we have no information on the males when it comes to technology or powers.

Ironwood: what are you talking about, Y/n Loud is the only male with powers!

Nezu: I'm afraid not Ironwood, he has the power to create anything that he wants as one of his powers, he can create powers for others and give them to others if he wants to.

Ironwood: shit we need to stop him before he makes the males more powerful!

Before anyone could say anything else, warning alarms were sounding around the grounds of Union, as the pro heroes and headmasters rushed over to the USJ, thinking that the League of Villains decided to attack again, but when they arrived inside of the USJ, seeing Class 1A, Team RWBY and Team Ryuko, at the center of the USJ, their was army of men stepping through a portal, some were white armored soldiers, some likes like they were hero costumes. The number of males present were about 250, 100 were 'special' types of males.

Nezu: who are you?!

Gaara: I am Gaara, one of the leaders of the land of males.

All Might: what are you here for?!

Gaara: we have come to battle you all, to see if you are worth our fight.

Yang: ha, like you have any chance against us!

As Yang lunged at Gaara, with her gauntlets ready to punch him, only for a wall of sand to stand between them, blocking her attack.

Yang: what the-?!

Gaara: is that all?

Yang: Not even close!

As Yang started punching the sand wall over and over again, not making any difference against the sand wall, Gaara made part of the sand wall hit her in the gut, launching back into the wall of the USJ.

RWB: SIS/YANG!

Then without warning, three males jumped out of the crowd and aimed towards the Union Students that were doing nothing.

???/???/???: Hello Sister, miss me~?

Kami: D-Denki?!

Gaja: G-Gajeel?!

Issaumi: I-Issei?!

Denki: Hello dear sister, did you miss what you have done to me~?

Gajeel: Yea Gaja, how was your life without your punching bag around~?

Issei: been a long time sister, how's been your fabulous life~?

Kami: B-But how, you were-

Denki: Dead, No dear sister, we weren't dead, we were rescued and brought to the land of males...

Issei: let's just focus on what we are here for, and that is show our stuff.

As the three turns toward the Union Students; Kami, Gaja and Issaumi came down the stairs and charge towards their brothers, believing that they are still powerless to fight back, but then....Issei, Gajeel and Denki powered up to higher levels, more than their sisters expected.

Denki: Lighting God Mode!!

Gajeel: Iron Shadow Dragon Mode!!

Issei: Welsh Dragon Balance Breaker!!

Denki/Gajeel/Issei: NOW, YOU"LL SEE WHAT HAPPENS WHEN UNDERESTIMATING US!!!

As the three charged at their sisters, Denki headbutted Kami in the gut, sending her flying into a wall, Gajeel launched at Gaja as she tried to stop him, but he turned into a shadow and attacked her from behind, and then sending her towards Kami and Denki before slamming her into the ground with Kami, and Issei lunged at Issaumi as she was in her own scale mail on as she tried to slash at Issei with ascalon, only for it to be encounter by another ascalon of his own, then Issei started making slashes of his own, his however was making hits, at the last slash, Issei made a powerful slash attack, launching Issaumi towards Kami and Gaja, crashing into them.

Issei: let's end this.

Denki/Gajeel: Agreed.

Issei: WELSH BLASTER BISHOP!!!

Denki: CRITICAL RED LIGHTNING!!!

Gajeel: IRON SHADOW DRAGON ROAR!!!

As Issei, Denki, and Gajeel combine their attacks together, launching them towards their sisters and the Union students and staff presents, Naofuma activated her shield and stand in front of Kami, Gaja and Issuami, she raised her shield as much as she can as the combined attack slammed into her shield, pushing her back until she slammed into the three behind her and into the wall.

As the rest of the Union Students and staff charged into battle, they were clashing with the males forces, having a disadvantage and losing the battle against them.

Then Gaara ordered a retreat back to the land of the males, one by one, all of the males retreated into the portal and at the land of males.
