Now arriving beside All Might, Takezushi was brought out of his joyous mood as he recalled that he had forgotten something very important. Walking up to his legal guardian, he said, "Hey, All Might..."

"What is it, Young Takezushi?"

"Let me try healing your wound again. Yesterday I made a breakthrough in my Yang Arts, and it might be possible to restore you to your previous peak." He had been so engrossed by Sage Art training to remember trying to heal All Might's grievous wound.

"Oh, uh… sure. Just don't get too bummed out if it doesn't work. I have been missing my entire stomach and most of my internal organs have been in their current shattered state for years now." All Might approached Takezushi as he agreed to let him try another healing session. Takezushi had already tried to heal his wounds but they were too severe even for a mostly Mastered Yang Nature and Shape Transformation. Now, that may not be the case…

Takezushi shrugged his shoulders, but before attempting to heal All Might again, his hands ran through a couple hand signs and an earthen dome surrounded them; the last thing All Might needed was for the class to know of his horrifying wounds. Leaving only the top of the dome uncovered to let some sunlight in, Takezushi's hands hovered a couple inches away from All Might's chest after the man had pulled up his shirt to reveal his scars.

Concentrating to the best of his abilities, a disturbingly bright white light manifested in the center of Takezushi's hand. In actuality the light would have been green if it were weaker, but because this was the pinnacle of Yang Prowess that Takezushi could actualize without using any hand signs, it blindingly white.

Now donning an activated Byakugan, Takezushi carefully guided the white light of pure Yang into All Might's body and silently let it spread through the damaged areas within. For a solid minute, Takezushi stood there, sweating even, as he was pushing himself to the limits of his abilities with Yang Release, before the light within All Might's body faded and Takezushi brought his hands down.

Despondently, he looked up to All Might and shook his head. "I guess we'll have to wait and try again when I develop Yin-Yang Release," Takezushi lamented. With only Yang Release, it seemed impossible to restore the missing stomach All Might had to surgically remove all those years ago. The best he could do with his current healing ability was to restore the damaged organs that were still present in All Might's body.

All Might put his hand on Takezushi's shoulder and said, "Cheer up, young man. It's perfectly fine that you couldn't completely heal me as you've already done more than enough! I'll have to see Recovery Girl to see exactly what you did, but I already feel much better than a moment ago. Now take down this wall, so we can get on to today's class."

Sighing, Takezushi completed another set of hand signs before the dome surrounding him and All Might vanished into the ground; it descended just as fast as it was erected. With Takezushi and All Might coming out of the earthen dome, they were met with the rest of Class 1-A already gathered.

"Whoa, where'd the dome go?!" Sato asked for everyone was thinking the same thing.

"I sent it back into the ground where it came from," Takezushi replied still a bit saddened that his second attempt at healing All Might had not gone over perfectly.

Sato wanted to continue asking Takezushi about the earthen dome, but All Might stepped in to say, "Ahem! Today we'll be going over an indoor battle trial. Villains are usually spotted outside. However, most of the atrocious acts of grand villainy are done indoors. Imprisonment, robberies, even the black market… Any villain with intelligence will be sure to lurk within the shadows."

"Thus, for this battle trial, we'll divide you zygote up into groups of two to duke it out as "heroes" and "villains." It'll be two-on-two indoor battles for today and after every round, we'll gather together and discuss how to better your acts of heroics." All Might concluded.

"What about this constitutes as 'foundational' hero studies?" Tsuyu asked. She was among the group that thought this was rather advanced material for the first lesson.

"All of it! The best way to improve is by learning from the field, so you can expect a lot of simulations and trials like this!" All Might replied.

"What are the conditions to win or lose?" Momo asked.

"Can I just blow the competition away?" Bakugou added.

"There won't be a threat of expulsion for this exercise like Aizawa sensei's Quirk Apprehension Test, right?" Uraraka worriedly asked as well.

"What would be the best way to determine teams for this exercise!?" Iida didn't hesitate to ask his own question.

"If there'll be battles of two-on-two, what will we do about Takezushi? If we include him there will be 21 students and whoever's team he ends up in will surely win easily..." Kyoka grumbled.

"Don't I look stunning in this cape?" Aoyama swaggered about…

As all these questions were being chucked at All Might at the same time, he couldn't help but stress, thinking, 'My Quirk is super-strength, not super-hearing...' With a wave of his hand, he got everyone to quiet down before he continued on with his explanation.

"Let's see…" He brought out a little cheat sheet he had with all the information prevalent for the class already neatly written for him. "For this exercise, we will have villains guard a nuclear weapon they intend on employing. The heroes must stop their nefarious plan before they succeed!"

"If the heroes capture the villains or reach the nuclear weapon before the time limit of ten minutes expire, they win. If the villains capture the heroes or obstruct them of reaching the nuclear weapon until the time limit expires they win. Your teammates will be chosen by a lottery and Takezushi will either severely limit his abilities if he is left as the odd man out or he will strictly play a supporting role should he enter a team."

"What?! Are we really going to pick teammates randomly?!" Iida asked.

"Well, pros usually don't have the luxury to pick who they'll be working with while they're on the job. That's probably what they're testing..." Izuku commented. He was met with praise with All Might while Iida apologized for this unnecessary outburst. Then without further ado, the teams were decided.

With all the teams decided, All Might reached his hands into boxes labeled "Heroes" and "Villains," and with a sense of suspension he said, "...And the first battle will be between..." His hands abruptly shot out of the boxes and on his left hand there was a grey badge labeled "D" while his right hand clenched on a white badge labeled "A."

"Midoriya and Uraraka as Heroes VS Bakugou and Iida as Villains!" Much to Bagukou's delight and Izuku's dismay, they had been pitted against each other. The Villain team was given five minutes to prepare and as they were deciding their strategy, Izuku and Uraraka were discussing their strategy as well.

Takezushi stood with All Might and the rest of the class and for the next couple minutes, they watched through the cameras that were prepped in the building, how the battle trial played out. After the preparatory time concluded, Uraraka and Izuku infiltrated the building through a window and after a short walk through the ground level floor, they were assaulted by a lone Bakugou.

Surprisingly, even without the use of his Quirk, Izuku managed to land a solid throw on Bakugou after having read his moves. After a short period of stalling, he succeeded in holding him back as Uraraka moved on ahead to complete the exercise alone. When Uraraka had left for long enough to feel safe in diverting Bakugou, Izuku turned to flee.

Minutes passed as Bakugou essentially turned to hunt down Izuku; apparently in complete disregard for the exercise's objective. Thus, Uraraka who had moved up through the stairs and had cleared out the rooms on the upper floors, finally found Iida safeguarding the mock nuke in the middle room on the fifth floor.

For some reason, she erupted in laughter and Iida found her out. Through the communication devices they were given for the exercise, it appeared that she told Izuku her predicament as he looked up at the ceiling at approximately their location. Alas, he was found out by Bakugou at that precise moment. Now in a most dire situation, Izuku could only watch helplessly as Bakugou aimed the grenade-shaped bracers strapped to his arms at him and pulled on the grenade's pin.

In the building's basement where the rest of the class was watching, All Might warned, "Young Bakugou, Stop! You'll kill him with that blast!" Ignoring, the number one pro hero's heeding, Bakugou spat out a couple words clearly seen by the camera before he struck a twisted smile and fired off a most devastating explosion; though not directly at Izuku, but within the range to be hit as collateral. Seeing this, Takezushi frowned for the first time, though he didn't move to do anything as he could read Bakugou's intentions.

As the building had a massive chunk of its side blown away by Bakugou's blast, Uraraka didn't hesitate to take advantage of Iida's then-distracted state and attempted to jump onto the mock nuke to "capture" it. The fact that she could make herself weightless with her Quirk stunned Iida, but before she won out, he managed to react and pick up the false bomb so as to prevent Uraraka from capturing it.

Now crashing onto the wall at the end of the room as her momentum from the jump wasn't met with any resistance, Uraraka was slumped onto the floor after releasing her Zero Gravity. Izuku wasn't faring well either as Bakugo's explosive combat style only became more devastating as time passed. But after managing to create some distance, he managed to exchange some words with Bakugou and two presumably went for a final clash.

Summoning his Quirk, Izuku sacrificed his right arm to his Quirk and his left arm to Bakugou's attack as he directed a fully superpowered uppercut to the ceiling. With the air pressure generated from his Quirk empowered super strength, everything was decimated along the wind's path. Consequently, Uraraka applied her Quirk on a pillar-like fragment of debris and after swinging it like a bat to stall Iida, she managed to jump onto the mock nuke to win the battle trial. Hearing that they had won, Izuku collapsed and Bakugou just stared at him in denial.
