I liked the idea of having Cry and Shinso become friends since their team up in the sports festival arc. Shinso seems like a character that indeed doesn't make too many friends unless someone really understands him. Cry was able to show him that and that's why they see eye to eye so well so far. How things will go in this arc, I don't even know yet. Currently in the manga, the third match had just finished. The fourth will begin soon so we have to wait some time before the 5th match finally begins. Anyways, enjoy!

"You'll each start in your own areas. The time limit is 20 minutes. If time does run out, whichever team has more members remaining is victorious. If both teams have the same number of combatants left, the match is a draw. Without further ado, let the first match begin!" Mr. Kan roared through a microphone. Our first match was finally underway. From our class, Shishida, Tsuburaba, Rin, and Shiozaki were chosen. From class A, Kaminari, Kirishima, Koda, and Asui, as well as Shinso. "Class A may have a disadvantage with having an inexperienced competitor, but if he uses his quirk right, Shinso might just be the strongest person fighting." I thought to myself as I was viewing the match. Cameras were currently on class A's team as they were heading to the centre of the battleground. Asui was climbing along the sides of walls, peering around corners to look for our classmates. She took it a step further by camouflaging her body agagisnt the wall, something I hadn't seen her do before. "Well that complicates things for us. The only one from our class who could possibly counter that right now..." I began to say to myself as the two teams finally met. Shishida came rushing around a corner, swiping one of his claws at Asui and knocking her to the ground. "I've got a pretty good sense of smell, ya know?" Shishida said to her which confirmed my thought. Tsuburaba was riding on top of Shishida's back as the two of them faced down all of class A's team. "Check out my new special move!" Tsuburaba yelled as he blew his solid air from his mouth. He could make it travel at faster speeds now and morph it into different shapes. He used it to make a small cube around Koda, basically trapping him in a tiny prison. The two of them went to strike the other team again, and Tsuburaba yelled out "Alright! Kick their asses Shishida!" Shishida replied and said "You got it! Leave it to me!" 

Right after he said that, Shishida came to a full stop. The expression on his face said it all, Shinso had taken over his mind. "But how? Shinso didn't talk at all during that exchange. You have to speak with him in order for him to take over. So why is Shishida under his control?" I thought to myself as I continued to observe the match. Shinso then stepped forward and explained what was going on. When he spoke, his voice sounded just like Tsuburaba's. "Artificial vocal cords: "Persona code."" Shinso said which only confused Tsuburaba. "How the hell are you talking and sounding like me?" He asked as Shinso let out a small chuckle. Shinso then explained and said "That's where this mask comes in. My artificial vocal cords: "Persona code," in other words, it's an adjustable voice-altering mechanism. I used it to mimic your voice so your buddy would respond to me. I then took over his mind and that was that." Shinso then charged at Tsuburaba and started to uncoil his capture scarf. Tsuburaba reacted quickly though and used a small opening to seal Shinso in an air prison as well. Tsuburaba then slapped Shishida in the back of the head, yelling at him to "Wake up!" The shock from the hit must've been enough as Shishida did come out of Shinso's control. "Be careful with how you respond. That Shinso guy has a voice changer. He used it to sound like me and brainwash you." Tsuburaba explained as Shishida nodded. 

As they were discussing Shinso's quirk, Kaminari took the opening to charge at them both. Shishida saw him coming and readied his claws to strike Kaminari. "What are you...? Don't hit him!" Tsuburaba yelled as he jumped off of Shishida's back. Shishida landed one of his paws on Kaminari, but he only received a huge shock thanks to Kaminari's quirk. If you were to even touch Kaminari for even a second, he would shock you with thousands, maybe even millions of volts of electricity. Shishida endured the pain that was surging through his body as he threw Kaminari through a wall. He got back up though and prepared to attack again. Tsuburaba who was still in the air was looking at what Shishida had just done. What he should've been doing was looking directly in front of him, as Asui used her tongue to immobilize Tsuburaba. Asui then began to run away with Tsuburaba, heading towards their teams prison. Shishida gave chase to them but his path was blocked by Kirishima and Koda who freed himself from his air prison. Kirishima hardened his body as Koda commanded nearby pigeons to attack Shishida. As they went to attack, Shishida deactivated his quirk, shrinking his body so their attacks would miss him. When he passed them, he activated it again, turning into his beast mode and grabbing on to both Koda and Kirishima. He then threw Kirishima straight up into the air, yelling "Shiozaki now!" As Kirishima was in the air, Shiozaki's vines appeared and captured him as he was falling. The vines then took him away, towards class B's prison. "Looks like the first person has been captured! Class B takes the lead!" Mr. Kan said while laughing maniacally. "Oh dear, he's starting to act like Monoma now." I thought to myself as we all continued to watch the match. 

Shortly after Kirishima was eliminated, Asui returned to the battle without Tsuburaba. "And just like that, Class A also captures one of the "villains."" Mr. Kan said unenthusiastically. She reappeared and attempted to immobilize Shishida with her tongue. Shishida, who still had hold of Koda, leaped away and jumped back first into a wall, hitting it hard. "I'm the only one here, a three on one fight wouldn't go well. We'l end this skirmish for now class A with a 2-1 lead!" Shishida yelled as he leaped away again, using the sides of building to propel himself. He was right though, our class now had a 2-1 lead as we saw Shishida place Koda in class B's prison. "Even so, it's still 3 on 3. We may have the lead, but with Shinso free of his air prison, he'll be harder to deal with without Tsuburaba." I said to myself. Everyone remaining on each team gathered together. Class B was bunched up around their prison and class A was standing in the centre of the zone. Both teams were probably trying to think of plans. "In terms of strength, after the previous exchange, class B has been left in way better shape than class A! At long last, will class A be crushed by my students!?" Mr. Kan yelled into his mic as some of the students in class A were getting mad at him for biased announcing. "I wish I could deal with him the way me and Kendo deal with Monoma, but that wouldn't look good if I just knocked out my teacher." I thought to myself as the match continued. 

The cameras zoomed back in to show us class A's team and Shinso. They were all grouped up, coming up with a plan. It seems they thought of one though as Asui began to create some sort of slime on her arms. She then rubbed the slime on Kaminari and Shinso's clothes. "What kind of plan is that? With Shishida's superior sense of smell and Shiozaki's reach, they'll be able to find you all much easier now." I thought to myself as I continued to observe the match. The cameras then panned back over to class B's team. Rin was guarding the cage to ensure Kirishima and Koda didn't try and break out. Him and the others were discussing a new plan of attack. Our team only need to capture 2 more people on the other team to guarantee victory. Shishida then turned his head away from both Rin and Shiozaki. "What is it Shishida!?" Rin asked as Shishida began to sniff. "There's three Asui's heading right toward our location!" Shishida said which only confused his teammates. "What do you mean three Asui's!? There's only one of her!" Rin said before Shiozaki started to speak. "Where are they now Shishida?" She said as Shida responded and said "Two are further away but one is nearby. Use your vines to take her out." Shiozaki then grew her vines and moved them toward the nearest Asui. "I've got something!" She said as she began to retract the vines back to her location. When they returned, they revealed that it was Kaminari who she had caught. "Now I see! That slime Asui made must have the same scent as her body! She put it on Kaminari and Shinso so the other team couldn't tell who was approaching them! Not bad at all, but we've seen how Shiozaki can overpower Kaminari, thanks to them fighting in the sports festival. He's done." I thought to myself. 

Kaminari came into view, wrapped in Shiozaki's vines with only one arm free. He used his free arm to fire some sort of disc near the members of class B. "Time for all of you to get a shock!" Kaminari yelled but Shiozaki was prepared. "You forget what happened to you during the sports festival. As long as my vines are connected to the ground, your electricity is useless." Shiozaki said as she used more vines to begin making a ball around Kaminari's body. "Don't think I didn't learn from our fight gorgeous!" Kaminari yelled as he began to release electricity from his body. "That disc I shot acts as a nice lightning rod. Even if your vines are connected right into the ground, my electricity won't be discharged and it'll be focused onto that spot in particular." He said as he shot a small bolt of lighting from his fingers. Like he said, the bolt went straight towards the disc, and Shiozaki was standing in between them. Beofre she could get hit, Shishida stepped in the way and received all of the damage from the bolt. He seemed to be stunned for some time after he was hit by it. Rin then spoke to Shiozaki, saying "The next one's coming! Spread out your vines again!" But Shiozaki responded and said "Right! Shishida, please give me their location." Like Shishida before her, Shiozaki's face turned into a blank expression. Shinso was nearby and had used his voice changer to mimic Rin. "Shiozaki, that's not me!" Rin yelled out but it was already too late. Shishida was freed from his paralysis and used his sense of smell to locate Shinso. He was able to find him and charged to his location alone. "I need to wake Shiozaki up fast! Otherwise things will only get worse!" Rin said as he began to run at Shiozaki. Before he could reach her though, Asui's tongue wrapped around her body. Asui then lifted Shiozaki onto a rooftop, far out of Rin's reach. Rin tried to save Shiozaki by creating his scales on his arms. He then fired several scales from his arms, attempting to hit Asui's tongue so she would let go of Shiozaki. He wasn't fast enough and Shiozaki was left on the roof, still under the control of Shinso.

Asui then returned while Rin was focused on Shiozaki. She leaped off of a nearby wall and slammed both of her feet into Rin, sending him flying into some pipes. Nearby, Shishida was heading toward Shinso's location so he could deal with him. He found him hiding behind several large pipes, talking into his voice changer. Shishida then began to claw his way through the pipes, closing the distance between him and Shinso. Shinso was prepared for his arrival as he had wrapped his capture scarf around a thick beam which rested above Shishida. When Shishida was close enough, Shinso dropped the beam onto Shishida's head, causing him to stop. Shishida wailed in pain but it wasn't over yet. When Asui had kicked Rin before and sent him flying, she sent him towards Shishida's location. Both Shishida and Rin collided heads adn knocked each other out. 

Class A's team then used the still brainwashed Shiozaki to immobilize Shishida and Rin by wrapping her vines around them. They then had her drag them to class A's prison. Once all three of them entered the cage, the first match was over. Class A had taken the first match and was now up 1-0.
