SPOILER WARNING (just in case)

Rui returned to the viewing room and stood with Chiyo and the others as they waited for the start of Izuku and Katsuki's match. Once the arena gate had opened, Izuku followed Katsuki down the street and nervously suggested that their team try to escape and avoid fighting All Might. Rui watched as Katsuki ordered Izuku to stop following him but Izuku continued pleading with his teammate to take a different route to the escape gate. Katsuki responded by shouting that he'll score higher if he defeats All Might.

'Come on, you two... get it together...' Rui thought to them.

As communication was proving difficult, Izuku continued to try and talk to Katsuki- only to have Katsuki smack him to the ground. He angrily demanded Izuku stop speaking to him and started to walk away, but Izuku asked him to wait and reconsider his plan. Irate, Katsuki continued to yell at Izuku and said he doesn't need his power to pass the exam and could win it all by himself.

'Katsuki, no... you need him to win... you have to work together...'

Chiyo glanced over at Rui as she watched with worry as her two childhood friends bickered. 'I wonder if she dealt with this a lot when they were children.'

Rui kept her gaze on the screen as Izuku yelled back at Katsuki, pointing out that shouting is why they never had normal conversations. But her worry only grew when All Might caught them off guard and destroyed the entire main road of the city with a Texas Smash attack. The shockwave created by Texas Smash sent Izuku and Katsuki flying back as All Might menacingly walked through the dust towards his students. He warned them to take the exam seriously or else they'd be sorry, all while surprising Izuku and Katsuki at how intimidating their teacher and hero could be. She watched as Izuku turned to run and tried to tell Katsuki to follow him, but Katsuki refused and All Might rushed towards him. Katsuki attacked with his Stun Grenade Super Move and jumped at All Might, only to have All Might grab his face. Rui's breath caught in her throat, but she was relieved to see that Katsuki didn't hold back and tried barraging him with his mini explosions. The blast didn't do much damage, though, and All Might slammed Katsuki into the ground.

'Katsuki..!'

All Might turned his attention to Izuku and managed to quickly get behind him. He taunted him and reminded him of the Hero Killer as Izuku activated his quirk One For All: Full Cowl and jumped away. Katsuki took the chance to jump at All Might at the same time and the tandem ended up running into each other in mid-air. Izuku still wanted to run while Katsuki only wanted to defeat All Might- admiring All Might too much to rush for a win. Katsuki recovered quickly and walked towards All Might, passing Izuku and ignoring his pleas not to fight.

Rui's heart sank a bit hearing Katsuki reply that he had to win because that was what a great hero did. She tried to keep her own emotions in check as she watched Izuku still trying to reason with Katsuki, even grabbing his shoulder. She watched Katsuki angrily tell Izuku to let go of him and she began to wonder if there was something she could have said before their match to help their situation. Suddenly, All Might called out to the pair used a broken fence to pin down Izuku from above before gut-punching Katsuki to the extent that he was sent flying and vomited while airborne.

"Granny Chiyo, he's taking this too far..." Rui said to Chiyo, looking at the old heroine fearfully. "He's going to seriously hurt them at this rate..!"

Chiyo's own concerns with how far All Might was taking the match were beginning to grow.

Rui returned her attention to the screen. "Come on, Katsuki... get up..!"

As Katsuki slowly recovered from the attack, All Might realizes that Katsuki's angry about the improvement in Izuku's skills and began to try and advise him that he still had much room to grow, and shouldn't waste his potential, but Katsuki shouted back at him that he'd rather lose than accept help from his former friend.

Hearing this broke Rui's heart because it meant that Katsuki had in fact seen Izuku as a friend. "Katsuki..."

All Might prepared to crush Katsuki but Izuku ran in and angrily punched Katsuki, yelling at him not to give up before quickly carrying him into an alleyway. All Might admitted aloud that he let his guard down and briefly complained about the heavyweights he was wearing while Katsuki elbowed Izuku in the back of the head as he ran down the alleyway- forcing Izuku to put him down. Izuku pleaded with Katsuki again, admitting that he didn't have a plan to run away from All Might or to defeat him. He asked Katsuki not to give up because he had always been the type of person who wins no matter what and added that the most amazing hero always won- just like Katsuki always used to say. Hearing this put Katsuki into a state of enragement as he was reminded of his own words. He yelled out and blasted the wall next to Izuku, telling him that there is no way they can get away from All Might without fighting.

Rui watched as Izuku started to argue but Katsuki loudly demanded he shut up before coming up with a plan to use maximum firepower on All Might and create some distance between them. He ran out of the alleyway to distract All Might, but All Might is unimpressed and believed it was a sneak attack. Rui could see that Katsuki was furious about having to work with Izuku, but she was shocked to see Katsuki cry out to Izuku as though to signal Izuku to attack. She watched with amazement as Izuku suddenly appeared behind All Might, equipped with one of Katsuki's Grenadier Bracers. She watched as Izuku pulled the pin and unleashed a massive explosion on his idol, but she gasped when she saw that the recoil from the explosion had injured his shoulder.

Katsuki began to fly away and ordered Izuku to run while he had the chance, but All Might speedily recovered and admitted that he was impressed with the team's compromise between running and fighting beginning his next attack. As Izuku and Katsuki rushed towards the escape gate, Izuku pointed out that the escape gate looks ridiculous but if they got through it, they would pass the exam. When All Might's next attack came, Katsuki noticed that it came from the middle of the replica city and it reached all the way to the gate. Izuku wondered why All Might wasn't pursuing them and Katsuki said that when All Might caught up, he'd blast him with the other Grenadier Bracer and try to give Izuku more time to reach the gate. But All Might overheard this and instantly appeared between them while mocking Katsuki before breaking both of the Grenadier Bracers with two swift punches and kneeing Katsuki in the chin- sending him flying into a building. Then he grabbed Izuku and slammed him into Katsuki when he flew back out. All Might pinned down Katsuki with his foot and pulled Izuku up by his arm, congratulating them for working together but reminds them that cooperation was a prerequisite and not an option.

"Granny, he's going to kill them! Please, do something! This is going too far!" Rui pleaded. She stared helplessly at the screen while Chiyo chastised All Might, growing angrier and angrier at All Might as he taunted Katsuki's strategy. Katsuki retaliated with a super explosion that blasted All Might away, wincing from the pain as he got up. He grabbed Izuku's mask and told him to prepare to fly before using an explosion to send Izuku flying to the escape gate. All Might used New Hampshire Smash to propel himself through the air and slammed his back into Izuku- sending him flying into the side of a bus.

"That's it, I can't stand by and watch this any longer!" Rui said, turning away from the screen and running out of the building, ignoring Chiyo's pleas to wait.

As Rui tries to reach the escape get as quickly as she can, Katsuki flew over using his explosions and took aim at his teacher- telling All Might that he couldn't win unless he went all out. He unleashed another super explosion on All Might and Izuku recognized the attack from the Sports Festival. Katsuki griped in pain, telling Izuku to run, but Izuku's back is messed up so it was difficult for him to move at all. Katsuki yelled at him to get moving and used more super explosions to keep All Might at bay while Izuku moved slowly towards the gate. However, All Might subdued Katsuki by slamming his head into the ground and asked him to stop fighting because his body was suffering. Katsuki replied by saying that he would never stop fighting because he wanted to win.

Rui reached the escape gate just as Izuku activated his quirk and charged at All Might, shouting at him to get out of the way before punching him with a smash of his own. She watched as Izuku grabbed Katsuki and did his best to drag him through the escape gate with him.

"Izuku!" Rui steadied Izuku as he tried to set Katsuki down, grimacing in pain.

"Rui...?"

Rui tried to smile at her friend through the tears that were brewing. "You did it, Izuku, you won."

"Is Kacchan...?"

Rui's smile faded and she looked down at Katsuki. "He's unconscious, but he's breathing..."

"Young Midoriya, you did well." All Might said, coming through the escape gate to join them. "I am not surprised that you saved Young Bakugo even though you could have just escaped. Your desire to save others is as strong as ever and there's not an obstacle that can stop you when you do."

"Shut the hell up, you monumental jackass."

All Might and Izuku both looked at Rui with shock as she glared up at the Number One Hero.

"Beg your pardon?"

Rui stood, unable to hold back her tears any longer. "You could have killed them! Do you even realize that?! Even with your heavyweights, you went too far, All Might! How could you?!"

"I-I..." All Might stammered, unsure of how to respond. He did not think Rui was the kind of person to explode like that. "It was all part of the test..." he tried to step closer to her, but Rui opened her hip flask of water and summoned a collection of ice shards- all of which were aimed at All Might.

"I don't care! Look at them!"

All Might fell silent and stepped back as Rui shot him another death glare- reminding him very much of her uncle- before kneeling down and beginning the healing process for Katsuki to try and stabilize him until help arrived.

"Rui..?"

Rui fought hard to get her emotions back under control. "It's fine, Izuku..."

When help arrived, Rui stayed next to Izuku and Katsuki, keeping up a water barrier and increasing the density- not entirely intentionally- to prevent All Might or anyone who was not medical staff from getting close.
