While the rest of Class 1-A are asleep, Katsuki takes Izuku to Ground Beta, the site of the Battle Trial where he and Izuku fought for the first time.
Both were unaware that Mikoto was following close behind. He wasn't sure what the two were up too but whatever it was. It was not good.
Nothing ever good came from when Izuku and Bakugo were alone. Mikoto learn it the hard way back in middle school when he found Izuku covered in burns and bruises from one of Bakugo's encounters.
Mikoto: (I don't like this...not at all...)
Once he was at a distance away from the two, he begin to observe what the two were talking about.
Bakugo: That power...You got it from All Might didn't you...
Mikoto:....?! (So he does know...)
Deku:....
Bakugo: Since you're not denying it...It must be true...
Deku:....What...are you going to do with the answer?
Bakugo:....I just don't get it...
Katsuki remembers the time where Izuku was weak and he was strong. The thought of it... infuriating him...
Bakugo: A quirkless good for nothing like you suddenly come out of thin air which manifested a Quirk and by some miracle you was accepted into U.A.
Deku:....
Bakugo: Then you received your Provisional Hero License while...I failed.
Deku: I....have received my Provisional Hero License for performing well.
Bakugo: SHUT UP!
Deku:...?!
Bakugo: I'm still talking!!!
Katsuki orders him to keep quiet and let him finish. Ever since the Kamino Incident, Katsuki has been putting the pieces together and has been thinking about it the whole time; Izuku is fully aware as to what Katsuki has discovered.
Katsuki finally realized Izuku received his Quirk from All Might. Having witnessed All For One's ability to steal Quirks and bestow them onto others as well as figuring out that All Might is an acquaintance of All For One, Katsuki hypothesized that All Might also has some form of Quirk transference because he has become weaker ever since coming to U.A and meeting with Izuku.
And to see that Izuku isn't denying anything, Katsuki knows that he is right about Izuku gaining All Might's Quirk.
Izuku knows that Katsuki is correct about him getting his Quirk from All Might and this is his punishment for trying to reveal his Quirk to Katsuki.
Deku: How is knowing the truth about his Quirk is going to help you?
Bakugo knows that he and Izuku has always looked up to All Might and seeing the person who he thought was a pebble on the side of the road being acknowledged by the person he looks up to he wants to put an end to it.
Bakugo: Fight Me.
Deku: Eh?!
Mikoto: What?!
Bakugo repeated himself.
Bakugo: We're going to fight here.
Deku: Wait! Why does it have to end up that?! We shouldn't do it here...we should reserve a training room and do it there!
Bakugo: If we fight seriously...we'll be stopped.
Deku: Kacchan...We don't have to do this!
Bakugo, for once, puts on a straight face, which was very unsettling for both Izuku and Mikoto.
Bakugo:...You admire him just like I do...Let me see for myself...If you deserve that power of his...
Mikoto: (I can't take this anymore. This is got to stop! He's going to get them in trouble!!!)
Just as Bakugo gets ready to power up his explosions... Mikoto shouted out to them.
Mikoto: STOP!!!
Deku: M-Miichan?!
Bakugo growled at the sight of the snow user who got in front of Izuku.
Bakugo: Get out of the way, Snowball! Unless you want to fight too!
Mikoto: I. Will. Absolutely. Not.
Bakugo:....
Deku: Miichan...
Mikoto: Bakugo...Just stop already...This is gotten out of hand and-?!
Bakugo: You know too...didn't you?
Mikoto:....?!
Bakugo: You knew too that Deku received that power from All Might...Why...? Why did it have to be him...Why someone whose didn't have a quirk gets All Might's in the first place?!
Mikoto: What the......?
By the look on Bakugo's face. He looked so frustrated and confused. Mikoto wasn't even what to think about all this...
Bakugo: Why?
Mikoto: Bakugo...?
Bakugo: Why? Why? Why?!!
Deku: W-What's wrong Kacchan?! Are you okay!
Bakugo: SHUT UP! DON'T FUCKING WORRY ABOUT ME! FIGHT ME DAMNIT!
Mikoto: NO!
Bakugo: Stay out of this Snowball!
Mikoto: JUST WHAT IS WRONG WITH YOU?!!!!!
Bakugo: ?!
Deku: ?!
Mikoto stomped over to Bakugo in a fury and grabbed his shirt lifting him in the air before shaking him in anger.
Bakugo: What-?! Let go!
Mikoto: NOT UNTIL YOU FUCKING TELL ME WHAT THE HELL IS YOUR PROBLEM?!
Bakugo: LET GO!
Mikoto slammed him to the wall.
Mikoto: ALL THIS FUSS ABOUT ALL MIGHT AS WELL!!! YOUR ANGER AND FRUSTRATION!!! I HAD IT WITH YOU!!! ALL IZUKU WANTS TO DO IS HELP YOU BUT YOU EVER DO IS BEAT HIM, ABUSE HIM, AND TREAT HIM LIKE CRAP BECAUSE OF YOUR STUPID EGO!!!!
Bakugo:....
Deku:....
Mikoto: NOW WHAT IS WRONG WITH YOU, BAKUGO!!! YOU BEEN A REAL PAIN IN THE ASS FOR ALMOST A YEAR NOW.
Bakugo: THEN TELL ME WHY!!!
Mikoto: WHY WHAT?!
Bakugo finally snapped and cried.
Bakugo: WHY DID I HAVE TO BE THE ONE TO CAUSED ALL MIGHT'S END?!!!
Mikoto: ?!
Bakugo: Back then...he saved me...and that ghost freak...from the League of Villains...but then...he was put out of the hero career because of me...Because I was weak......
Mikoto:....Weak?
Deku: *Sad* Kacchan....
Mikoto finally puts Bakugo down and looks really lost...
Mikoto: *Softly* Bakugo...You're not weak...who...told you you was weak...?
Bakugo didn't say nothing at first but looks away and mumbles...
Bakugo: The Old Hag...My Mom...
Deku gasped in shock while Mikoto went quiet again.
Deku: (Auntie Mistuki said that?!)
Mikoto:....
For once, Mikoto felt sorry for Bakugo. Just hearing his side of the story made him wonder how was Bakugo raised...
Deku: Kacchan...
Mikoto pulls an arm out preventing him from coming any further.
Deku: Miichan?
Mikoto: Wait...
Both of them looked back at Bakugo.
Bakugo: IT'S NOT FAIR... IT'S JUST NOT FAIR! WHY...WHY DID IT HAVE TO BE SOMEONE LIKE DEKU...TO HAVE ALL MIGHT'S QUIRK?!
Mikoto's eyes went wide upon realization. Something along those lines had his brain moving before something clicked inside.
Mikoto:....Bakugo.....All this time...So that's it...
Mikoto get it now. He finally understand.
Bakugo: ....What?
Mikoto:....You're scared of Izuku, aren't you?
Bakugo: H-HAH?!
Mikoto: You was scared that he would outshined you. So you saw him as a threat...
Deku: (A-A threat?! Me!) W-Why...? I would never hurt Kacchan.
Mikoto: That's not what I meant by that, Izuku. Bakugo knows you respect him and still look up to him...but the thing is...Bakugo...never wanted to acknowledge you...
Deku: ?!
Bakugo:....
Mikoto: Something tells me at some point, When you guys were younger, maybe when he got his quirk, or at least sometime in middle school...He begin to see that you were no longer weak. He was scared that you would catch up to him...So the only way he prevent that from happening...was to make sure you got bullied and received no help from anybody....but it looks like that backfired on him.
Mikoto then looks at Bakugo.
Mikoto: You weren't going to get away with it, ya know. Even without my involvement, someone could've said something. You can can't keep people silent unless you kill them....if that's what you wanted.
Bakugo: What the fuck do you mean, Snowball?!
Mikoto felt the urge to rip his hair out.
Mikoto: Did you forgotten what you did?! I'm talking about your little inferiority complex! It led you to become something less than a hero!
Bakugo:......Hah...?
Mikoto: All this time...you wanted to be a hero...but you were acting like a villain!!!
Bakugo: No...That isn't....
Then he remember what Niko said back at the Kamino Ward.
"I heard stories about you. Oooh. Where to start. You believe you're better than others? You pick fights to make you look better. You scream and shout at others. You make death threats at them. Heck...I heard you even bullied a few students or more into submission. With your attitude, you have the personality of a villain~~~!"
Bakugo:.....
Mikoto: Bakugo...When are you ever going to let this go? Can't you see all the things you had done...were nothing but painful memories. You had not just hurt Izuku. But you ended up hurting yourself. You let your frustrations get the better of you.
Bakugo: SHUT UP! LIKE YOU KNOW ANYTHING, SNOWBALL!!! STOP TRYING TO ACT LIKE YOU KNOW ME!!!
Mikoto:....Oh Bakugo...I actually pity you...
Bakugo: Are you looking down on me?!
Mikoto: SHUT UP! Am I looking down on you?! YES! Because of the way you acted towards my friends! Towards Izuku! Towards me and my family! You belittle people! You insult them! You mock their chances of being heroes! You made fun of my family. My insecurities. Izuku's as well.
Deku looked away as Mikoto continued to rant. He never thought that Mikoto would be this angry about all the things that had went down between him and Bakugo for years.
Mikoto: And you got some nerve threatening Izuku after this time!
Bakugo: You both ruined my life...
Mikoto: Oh, we ruined your life?! Everything gotta be about you, huh?! YOU! YOU! YOU! NO ONE CARES BAKUGO! IT'S NOT ALWAYS GOING TO BE ABOUT YOU! ME AND IZUKU DID NOT RUIN YOUR LIFE! YOU RUINED YOUR OWN!!! SI DON'T OIN THE BLAME ON US!!!
Bakugo:....
Mikoto: I warned you Bakugo! You should consider yourself lucky you're still here at U.A and Izuku and his mom decided not to press charges for your QUIRK ABUSE!!! Think about it, that day you told him to kill himself! I'll ask again...What if he actually did it?!! How will live with yourself?!!! DID YOU EVER STOP TO THINK ABOUT HOW YOUR WORDS HURT?! BECAUSE YOU CAN NEVER TAKE THEM BACK?!!!!!
Bakugo: H-Hah?!
Mikoto: You know what...I'm done Bakugo...I'm done...I had it with you...Enough is Enough...I'm not going to allow you to hurt Izuku again just to make yourself feel better. It's time to stop...
Bakugo:.....It's not fair.....
Mikoto: When you will learn Bakugo...that everything that happened so far with you...was your own fault. When will you learn? When will you learn???
"That your actions have consequences..."
Bakugo:...
Mikoto: Now...Leave Izuku alone. He isn't weak...and neither is you. No matter what anybody says. If Izuku says you can still be a hero. Become one...and stop acting like a villain...
Bakugo:.......
Mikoto then remembered what Kirishima said. Bakugo should consider himself lucky that someone like Kirishima is trying to look out for him.
Mikoto: Just get some help...That's all I'm asking...Fighting will get you nowhere...It may be hard to trust people but at least someone like Izuku tries to help people out there like you...
Katsuki went quiet for what felt like a long time. Espression was unreadable before he finally spoke with one single word.
Bakugo:.............Alright.
Deku:....
For what felt like wasted years, Mikoto took a breath of relief. Finally...
Mikoto: I'm glad you agree...because what you and everyone else back in middle school done to Izuku...he didn't deserve it...No matter what you guys said...Quirkless or not...he didn't deserve it... It's just sick and twisted how this society is...horrible isn't it? We live a hero world where people are supposed to saved. But those who don't have that power get mistreated by those who were supposed to save them...now tell me...is any of that even heroic? Being Number One isn't everything as you think it is...
Bakugo:....
Mikoto watched him stand there for what felt like an eternity. He couldn't stand this pettiness anymore. He didn't even want to look at Bakugo anymore either.
Deku: Miichan?
Mikoto: I'm sorry Izuku...I'm just tired...tired of all this drama...I need some ice cream...all of this have just been exhausting...
Mikoto told Izuku he was leaving since Bakugo looked like he been subdued.
Deku:...Miichan...Is it okay if I come with you...?
Mikoto: You sure?
Deku: *Nods* Yes...I'm also tired...I think we kind of woke up the neighborhood...
Mikoto: *Dry laugh* Haha...It sure looks that way...Also...I called Aizawa and All Might earlier...about this...
Deku: Oh...
Mikoto: Yeah...I couldn't just not just sit by and let all this go down again...So I told them before I left the dorms and yeah...you guys are probably in trouble right now...My Bad...
Deku: Don't worry about it...
The two boys begin to leave until Bakugo called out to one of them...
Bakugo:........Deku.
His voice sounded utterly broken once again.
Deku: Ah...Yes...Kacchan?
Bakugo:.......
Bakugo mumbled something inaudible...but to Deku...it sounded he was saying...
"I'm Sorry..."
Deku:......
Mikoto:.....
No more words were exchanged as Bakugo left for the dorms as Deku and Mikoto went back as well to get some ice cream.
But all three boys got caught by Aizawa and All Might due to Mikoto calling them a little while earlier.
Aizawa gave Izuku and Bakugo a small punishment for leaving the dorms past curfew and almost fighting and told them they will be doing all of Class 1-A chores for the week.
At least now...things were starting to bright up...
But by now, Mikoto just hoped that all that the whole thing between Izuku and Bakugo has finally been put to an end...
Because Enough Was Enough!
