When the mock battle began, Goshi, Mizuno, and Kuroda were one team, Hino, Fennal, and Astral were another team, and Reiko, Senda, and Sachi were the final team. Each of the three teams in the hero's side split off to the right, left and advanced forward searching in the large city for the villain team's base as each of the three teams had radios to one person in each team to keep contact with on another. While they traverse through the buildings thanks to some of their quirks such as Fennal's pathways or Sachi carrying Reiko and Senda.
However, Euro suddenly spotted them from the shadows and teleported away as he radios to the others "I have visual, it seems they split up and are searching for our base"
"Copy that, stay with your role and don't get spotted"
The radio cut off and Euro continued his observation.
On team three Reiko is keeping watch making sure that there are no weaknesses from how they are getting through building to building, as they are hanging onto Sachi's legs as she is swinging herself from the lamp poles. "How are you holding up, Sachi?"
"I'm getting the hang of it, but we know Uni is more experience than this"
"That is true, if we're thinking about the villain's mobility then Uni is most likely to do hit and run tactics."
Then they suddenly heard a spring bounce at them, Reiko quickly sensed it and told Sachi to swing right as they narrowly dodged an attack by Uni leaping towards them. They saw Uni already caught up to them as they needed to fend off against her while the others continued to search.
Meanwhile, team one and two found the base and observed Mizuno using her binoculars, seeing Hamour, Poller, Blaze, and Delmon patrolling the base and watching their movements.
"What do you see?"
"I see their toughest villains, but my guess that the rest is in the base no doubt waiting for us so Aoi and Doc could use their quirks on us"
"Then we'll play it wisely"
"Without Reiko?"
Goshi nodded, as Mizuno kept watch on the patrol patterns and kept one radio at side as the rest took the only one. While the one radio was given to Goshi as he is the most trusted hold on, they quietly evade the four villains with the help of Mizuno. But when they were inside they were on their own as Mizuno cannot see through the inside of the warehouse and without the help of Mizuno's vector sight. They moved quietly as they inside the warehouse they saw Flare and Aoi talking to each other, and Doc Doc walking towards them, they had a chance to attack them. But then moving ice statues suddenly came at them, those ice sculptures were made from Flare's quirk and the controls were from Doc Doc's quirk, they realized how they had underestimated that they were already outnumbered even further. The frost sculptures then warned the three as they noticed that the heroes fought and the ice sculptures were destroyed.
"Looked like my creations founded them" Flare looked at Doc "should we handle them now"
Doc Doc nodded "Aoi warn the others, we'll take care of them"
Goshi quickly radio Mizuno "Rei we've been compromise, move quickly"
"On it" Mizuno hung up the radio, but was suddenly pushed back as Euro appeared. "That would be enough for a scout to be aware that all surroundings can make someone vulnerable."
Back at the base Goshi didn't hesitate and made a sword bean slashing at the shelves crashing and blocking the entrance from the other villains. "Fennal, Kuroda get the intel and stop the production. Hino, Astral with me" Fennal and Kuroda ran as the other three prepared to confront Doc Doc, and Flare as there were more ice sculptures.
Meanwhile Sachi holding Reiko and Senda were quickly avoiding Uni's spring attacks, Senda tried to fire his foam at her, but she was too fast for his foam to attach to her. "She's faster than we thought"
"That's true, but with her slinky limbs she can only reach at a certain differents" Reiko looked at the ground and the walls "Senda take off your braces and cover everything"
Senda listened and took off his bracers and gave it to Reiko to hold, as he reached out his arms as he spewed a large amount of foam around the area from buildings to buildings and across the ground. Uni is suddenly having trouble as her motion and mobility were limited by Senda's foam as she accidently fell in and her legs were caught and she was unable to move.
"Great job Senda, let's make out may back to the others"
At the warehouse Goshi is taking down many sculptures, and Hino and Astral were firing their projectiles as Flare made ice walls to protect them from their attacks. Fennal and Kuroda were running to get the intel as the walls suddenly burst as Blaze walked in with a powerful grin on his face "you didn't think we be left out"
Kuroda quickly stepped forward preparing his hands static with electricity, but Fennal quickly used his paths on some objects as it fired, hitting Blaze and burying him in rubble. Kuroda quickly placed his hands onto the rubble with a static bind making Blaze unable to move for now. Then at the entrance the debris that was blocking the way, was broken through by Hamour slamming his head allowing for Poller to run at them and Aoi getting ready to sprout her pollen.
Outside Mizuno is carefully dodging and predicting Euro's next move as he phases in an out teleporting around her. But then Sachi grabbed her and pulled her away and looked at them "well what took you guys so long, we already attacked the base"
"We know, Uni just distracted us"
Suddenly Mizuno saw spikes and power balls were heading towards them as Sachi quickly protected them all, blocking the spikes and balls as it came from Delmon and Mondo.
"Didn't think you forget about us"
Reiko looked at the warehouse, detecting some infractures in it and looked at the others "Rei, Sachi, keep them busy. Senda we need to help them" they landed and Sachi and Mizuno charged towards Delmon and Mondo.
While Reiko and Senda headed into the warehouse seeing that the fight had already begun. "Senda make sure this warehouse doesn't fall, I'll help out Goshi and the others"
He nodded and quickly put on his braces and fired some of his foam at the ceiling making sure it doesn't get damaged later on. Reiko headed for Goshi first, but Poller blocked her and attempted to strike at her only to be then blasted by foam by Senda. "Don't hesitate Reiko, your our strategist"
Reiko nodded and headed for Goshi sensing the infrastructure and weak points of each ice structure, but also saw how reflective they are almost see through. She looked at Astral and saw her camera dangling "Astral use your camera!" Astral didn't hesitate as the heroes covered their eyes and a large beam of blinding light showed blinding Flare, Doc, and Aoi. It gave them the opportunity for Goshi to destroy the remaining ice sculptures while Astral, Hino and Reiko quickly restrained the three remaining villains, as Fennal and Kuroda came back with the intel they took. Then the horned blared as the mock battle was over and the hero team won.
All nineteen students freed from some debris and foam they all walked to their teacher as he was impressed by many seeing how they combined each other's quirk or using their quirk against them.
"You all did good, that will be all for today, let's head back to class"
They all then walked back heading to a bus that brought them later back to U.A at the locker rooms they each took off their hero costume and back into their school uniform. This mock battle everyone experienced was something to be remembered seeing how each can adapt to a situation no matter how many or how few members are on either side.
