Although we spent to what seemed like months in the Back Channel, it was merely a whole day on the outside. Within that time I made sure to bulk up Midoriya and to educate All Might. Although his education was more on a singular subject, cells, rather than an expansive amount of subjects. Throughout the entire time I went back and forth to the Toriko universe to obtain lower level ingredients for them. On the last week of the Back Channel training, I sparred a little with both of them. Their goal was to at least graze me which they barely managed.
During the time we spent training, I made sure to enforce a lot of Midoriya's backbone. I hated the fact that Bakugou kept bullying him without too much retaliation. By the end of the training, the once beefy version of All Might slimmed down. I told him that by compressing his muscles he can get better control of One-for-All due to the strain of maintaining all that power compact. Midoriya grew a bit taller and more muscular for someone of his age. I broke a senzu bean in half and gave it to them on our last day in my Back Channel.
Sage: So, how do you guys feel?
All Might: Like I have been reborn. The day you returned my body to its physical peak I felt like my body before were nothing compared to now.
Midoriya: My senses have been heightened, I can feel everything and nothing. If that makes sense.
Sage: What you are feeling is a sense of power. It is a double edged sword that can empower or kill you. Remember to not lose your sense of self. I may have taught to toughen up physically and emotionally but I can't do anything if you do not take care mentally. (To All Might) It seems that you will not give up your number one hero spot for quite some time, eh All Might?
All Might: HAHAHA!! If anything I feel like you gave me back years of my life. At first I was afraid to tell Midoriya-shonen that All-for-One shaves ones life, but it seems that the understanding of the power itself was shallow with myself and my predecessors.
Sage: Now that you have that sense of power let me bring you back to reality. This will be the final lesson you guys can learn from me. Simply try to withstand the pressure.
Midoriya and All Might stood before me but didn't know what to expect. I breathed calmly as I gave them a blood thirsty look filled with Haoshoku no Haki. I didn't give them a full brunt of it since I can kill weaker people. My Back Channel disappeared as I eclipsed the sun from the area. All Might was on one knee struggling to stand while Midoriya was sprawled out on the floor struggling to breathe but still conscious. From this universe and considering who I am applying my pressure to, it wasn't bad. I released my Haki to let them up.
Sage: So, what did you learn?
All Might: No matter how strong one gets don't let it get to your head, for there will always be someone stronger ahead.
Midoriya nodded.
Midoriya: I guess with the new sense of power I had I let it go to my head. I see that now.
Sage: It's good that the both of you understand. Just remember that sense of power, use it, embrace it but don't let it control you. Let's go back, I'm in need of a nice shower and some decent sleep.
All Might & Midoriya: Yeah.
I teleported us back to the school and went our separate ways from there. I am going to the Dragon Ball universe after the League of Villains attack the school training grounds. I have no interest in replacing Champa as the God of Destruction of Universe 6, so I will not kill him. I will only bring him close enough to death that he will wish for it. If anything, I want to fight the other Gods of destruction if I can. Since Belmod had Doppo as a replacement I can get away with killing him.
The next school day everyone was surprised to see the new Midoriya and the slimmed down All Might. While the kids were at lunch all the teachers were called to the principal's office for an emergency meeting.
Nezu: What the hell happened?!
All other teachers: Yeah!!
All Might: Sage-kun healed me. After that we spent some time training. Sorry that we took a couple of months from classes.
Aizawa: What are you on about, All Might?! We just saw you and Midoriya yesterday!
All Might: WHAT?! But we spent months training in some oasis in the desert how could we have only spent a day?!
All the teachers then turned their heads and stared at me. Since no one was saying anything I just smiled, shrugged my shoulders and walked out of the room. I had no time reference as to when the day that the League of Villains will attack the students, hoping that they can use them as hostages against All Might so I will wait the few days until they do. I don't know how the established laws work here but I will try to kill me some villains. In Midoriya's class they had the same reaction as the teachers to Midoriya's change, especially Bakugou. I will make my way back home for a bit before thrashing Chumpa.
The day before the field training day, the media broke into the school grounds in order to get the exclusive on All Might. Ever since All Might announced that he will be teaching in UA, the media has been in an uproar for the story. When the incident died down, the doors were found destroyed and crumbling. Of course I knew it was Tomura Shigaraki, but it only made me certain when they will attack.
Today is a field training day for the students, since I know what will happen, it will just be a waiting game. Unlike in the original, All Might was called off to do teacher related duties elsewhere but I highly doubt he would run to the training grounds since he knew I would be there. In order to get used to his rediscovered powers and renewed body, All Might did some Hero work before coming in to school.
While in the training grounds, Thirteen, the Rescue Hero, was giving the task the kids had to complete for the day in order to rescue people in different environmental situations. The training grounds were big and diverse so it does become a great environment to learn how to rescue people. I will wait until the kids are transported away before I start on Shigaraki and the Nomu. Aizawa approached Thirteen.
Aizawa: Hey Thirteen, I don't see All Might anywhere. It was supposed to be the four of us today for the exercise.
Thirteen: He was called to Principal Nezu's office and will be here later.
After Thirteen gave a lecture on the different types of perdicaments on rescuing people, I felt the League of Villains approaching. The smile on my face was apparent despite keeping my presence hidden. I might as well looked like the smiling cat from the Disney Alice in Wonderland cartoon movie. Midoriya knew, from my smile, that enemies were approaching and powered himself up. The other students looked at him with bewildered expressions except for Bakugou. Bakugou no longer looked at Midoriya as loser or weakling. He looked at him as a rival.
Appearing through black fog portals, villains started emerging.
