As Ryo arrives inside of Ground Beta it was chaotic as Ryo called in as many military rats as possible from close combat to range as many got so much casualties as medic rats doing their best to heal their injured rats as other rats are holding on to their positions as long as they can. meanwhile with Ryo commanding the rats where to flank and reinforce also helping with his bow and arrows he began to use his archery skills to the test. With a draw and release arrows began to fly as it hit any robot thanks to its bodkin design to penetrate through the armor of the robot's same thing with all of the Militia archers, Archers, and Longbowrats. Firing a volley of arrows with the frontlines where the rats are taking most of the damage. as the students watching this is like watching a war movie unfolded in front of them a commander an army and enemies from all corners. In which they were dumbfounded to see rats reaching a size to an adult person's thigh as they form formations and strategy.
"Is that... an army of rats?" one of the students asking then another who checked his phone showing the social media page showing a photo of the same rats "Wait those rats look familiar" one of them looking at his phone then the rat.
In which the see a sea of metal scraps as rats began to attack as Shield rats, and Legionaries pushing and attacking the robots as Ryo uses his skill cards from Defense and Counter to boost. Then a line of Rataphracts charging towards the swarm of villain boats striking with their duck steeds waddling fast as their long lances penetrated the robot's armor.
Meanwhile in the monitoring room
they see the staff and teachers of U.A. Academy as they look at the many potential students.
"I see we have many potential candidates for the hero course" as a chimeran mouse or bear also know as the principal of U.A. Principal Nezu said as he continues observing everyone in the monitors as well as some heroes who are teachers as well.
"Yes, but there are several people that piqued my interest but as well as one more...that kid" a man with hair reaching his shoulders looking like he had barely any sleep pointing at one candidate that being Ryo. In which everyone watches which monitor as they saw Ryo and his Rat army as high as a normal person's thigh and they formed a familiar formation from the Roman legions. The testudo and archer type rats shooting down their enemies with a rain of arrows and other rats one with dual wielding axes and the other holding a black flail and wearing black armor both intimidating and effective. But they see also dead rats as well who have unfortunately perished from the battle as their bodies disappeared and they see a rat like spirit floating away from the ground.
Many of them were shocked to see this as they began to ask on who is he and what's his quirk.
"Let's see here...Ryo Mizuki Quirk Ratropolis his quirk allowed him to control special cards that called in either Soldier, Economy, Boost, and Infrastructure. Each card is labelled by color. And he can also summon a door that will lead him into another dimension which is a city of rats like them. And all of the rats treated him like a leader as they all follow his command without any hesitation." Nezu reading into his table out loud to let them know his quirk "I want him in my class" The tired man said without any hesitation as the other heroes murmured about him saying that without any hesitation.
Meanwhile in the Practical exam area Ground Beta
At first the rats are winning until they felt a slight tremble on the ground as both Ryo and the rats were confused as they began to look around the area as they see something that made Ryo and the rats tremble as he witnessed the zero pointer. Ryo and the rats were trembling in fear at first as all of the test takers began to run to the opposite direction as everyone is screaming run. In which Ryo them commanded all of his rats to run in which they did until him and his rats heard someone in trouble. As they look at who is trapped in which a pink haired girl with horns and pink skin got crushed by rubble in which Ryo run towards to help her and a few rats followed as it was a Berserker, Dark knight and a Legionary followed as Ryo tried to lift the massive piece of concrete.
But he can't until a Dark knight and Berserker helped as they both began to lift the rubble as they did it was enough that the girl began to crawl out of the rubble as she did Ryo and his rat companions then dropped the rubble. As they see the shadow of the 0 pointer they began to run away but the pink girl felt her leg was sprained in which Ryo had no choice to carry her piggyback style and with the use of the march skill card to increase movement speed both Ryo and the Rats then run as fast as they can. As they did the other rats then squeak and hiss for them to go faster as they did Ryo then crashed right into the rats also catching him and the pink girl as well. And Ryo call them out to Retreat as they did as the Banner rat blows his horn to make them move faster until a familiar green haired boy then running towards the zero pointer as he jumped so high then he formed a fist as the sleeve of his jumpsuit ripped itself apart then he punched the robot right in the face as it caused massive damage.
And the zero-pointer exploded and turned into scrap metal Ryo wasn't the only one shocked, but his rats and the other test takers are also expressing their shocked looks. Then Ryo realize that he was going to fall in which the rats then moved where the boy will fall and Ryo then using his quirk to open the portal to Ratropolis as he grabbed a big roll of cloth and the rats then cut it and pulled the cloth to make a somewhat of a safety net used for saving falling people. As the boy was about to hit the cloth but someone slapped him and almost hit one of the rats, but he was floating.
"... Release!" A short Burnett hair girl then touched her fingers together and dropped Izuku on the ground or well right at the cloth. In which he began rolling down and the rats just ease the tension and put him on the ground slowly as both of his legs broken and his one arm broken as he breathed heavily. As the girl released a sigh of relief, but she then felt her body wanted to hurl and she did right in front of the rats as the rats were grossed out. As they did, they hear the alarm blared and Present mic announcing that it's times up.
