After speaking with Nezu in the cafeteria the teens knew that there must not be any interference that could possibly ruin a very precious event for many who attend UA. This event would make a precious memory for Eri as for the third years since it's their final festival. 

 There are only 2 days before the Cultural festival would begin and many of the classes were in the final phase of practices when Izuku and Ochako told their class what the principal said many were shocked that this whole festival would be cancelled if something goes wrong. From that point on they practiced hard to make this event even more memorable. After practicing Izuku decided to make a couple calls to his mentors hoping they could sacrifice some of their time to help provide extra security. He was in luck because they all agreed during the last two days that UA had to practice. Eri was invited to see all the acts and play at some stalls. All in all it was safe to say this festival was going to be one of the best in years that the school was going to have.  During these days of fun Ochako and Nejire were helping Izuku make sure Eri was enjoying her time the funniest thing occurred when Eri "hey mama?" Then simultaneously both Ochako and Nejire responded then when it registered in their heads what they said both girls blushed heavily.

Day of festival

When the day of the festival came Izuku gathered everyone in the common room in order to give everyone a pep talk.'Listen up everybody today we make this the greatest event in all of UA history! We've worked long hours to make our performance perfect and we've put in hours of dedication to make this event special for everyone in attendance today. Let's go beyond Plus Ultra!!" As everyone cheered in excitement 1-A didn't have a show until late in the afternoon so many went to walk and check out what other classes had done. Since it was the official day of the festival many it would be the day Izuku and Ochako could take Eri to enjoy the festival to the fullest. Both teens took the little girl to get plenty of food and saw they were able to catch the full performance of 1-B's play which Eri thought was a little confusing but enjoyed it nonetheless. Mirio and Tamaki eventually joined the little group and told them about the beauty pageant Eri saw the entire show and when it was Nejire's turn she looked drop dead gorgeous Eri said in a low "Mommy looks pretty." Izuku nodded and said "she sure does." Izuku blushed as he practically agreed that Nejire would be Eri's mom.

On Stage Nejire had done a little routine using her quirk to fly and shoot small bursts of her power making it look like a fireworks display. The audience roared in excitement as she blew a small kiss towards Izuku's direction . Many of the guys fought among each other saying the kiss was meant for them when the judges were done debating who was taking home UA festival queen in a landslide Nejire Hado was crowned queen as her goal to be Festival Queen had come true in her final year.

With Bakugou 

Katsuki has been sulking more than ever not only was he never going to be a hero but during the festival he had to help the most but it didn't seem all bad since Camie came to visit him. The two were talking and noticed a pair of suspicious individuals and decided to tail them when they realized it was the Villain Gentle and LaBrava. Camie had an Idea "Bakubabe how about we take them down UA would have to reinstate you in the hero course and Deku would be a thing of the past." Katsuki had a devilish smile as he enjoyed the genius plan Camie came up"

Back to Izuku 

Izuku, Ochako, Nejire, Mirio and Tamaki were showing Eri around the festival when an announcement for 1-A to prepare for their show came up. "We gotta go guys we'll see you at our show." As Izuku and Ochako returned to their class they got ready for their performance and once in place the curtain rose up and then a smooth beat from the drums played as the rhythm kept building up the other members of the band then began to play their parts. Nejire was holding Eri and the group had a great spot to view the show when Kyouka began to sing, Eri for the First time had the biggest smile which Mirio noticed and cried tears of joy since Eri had finally smiled but then it turned to a frown when Mirio saw a man suddenly land on the stage taking the mic as the performance was interpreted. "I am The criminal Gentle here to carve my name into history" before he could ramble and continue to explain his purpose there was a massive buster sword and Gunblade pointed at him " Gentle you're under arrest for trespassing" Catalyst held him in place as the teachers were surrounding the stage when suddenly Two Bakugou's charged at gentle one was an Illusion the other was the real deal.

The explosions that Katsuki caused destroyed Kyouka Jirou's instruments then in the confusion Gentle made his escape running through the entire campus while bakugou chased him as stalls and booths were left in ashes. Many of the students who witnessed this destruction had tears running down their faces. All the hard work had gone down the drain and they were all informed that the festival would have been opened to their families the following day.

All Izuku could focus on was Eri who had her face buried into Nejire's chest. He saw the little girl trembling and noticed the wet stains on Nejire's uniform. She was crying. Izuku had vowed to give her the best day and it had all gone to hell after Gentle made his escape Katsuki and Camie returned with proud looks as Ectoplasm, Miruko and Ryukyu went after the villain.

When the pros left Katsuki had the balls to ask " Am I back in the hero course again?" He was met with one ferocious hook to the jaw he saw Izuku standing over him"You Idiot! You ruined everything he was about to surrender! look at the destruction you caused! Today meant a lot for so many people yet you ruined it! Katsuki bakugou and Camie Utsushimi you're under arrest for aiding the escape of a criminal and quirk usage without a license." Before Katsuki could say anything both he and his accomplice were knocked out by Midnight and put into quirk restraining handcuffs and dragged into Nezu's office he then grabbed a microphone and addressed the school. "Students I know you're all upset as am I. We did our best to maximize security here but it wasn't enough. It's with a heavy heart we cancel the cultural festival. Please head home to your families."

Izuku had asked Nezu about Eri but he had just asked if she could stay with him and his family. He agreed and asked Nejire and Ochako about coming with him. Meanwhile Nezu and the other teachers would decide the fate of Katsuki and Camie. “The kid has not learned anything from his previous actions GRRRRRR *HOWL*!” “Besides the howl, I agree with Hound Dog on this one sir. Bakugou has now not only caused destruction of property, but he’s also ruined the chance of apprehending a criminal that’s been on the police’s top radar for a while now.” Aizawa pointed this out as Midnight makes one thing perfectly clear. “I’m not teaching him anymore.” Everyone looked at her for an answer. “I’ve warned him, you all have warned him, EVEN MIDORIYA TRIED TO PITCH IN ON HELPING US AND HE HATES HIS GUTS FOR WHAT HE’S DONE! I refuse to teach someone who has such a disregard for public safety and the law.” Nezu and AllMight thought about this as well before answering. “I believe we are left with no other choice. This must be brought into the hands of the police with expulsion certain this time. Are there any who are opposed to this idea?” The small rodent looked around the room seeing none of the teachers or assistants against the idea. “Then it is settled. We will also address this to Shinketsu about Ms. Utsushimi’s involvement.”

After a rather unsettling call with Shinketsu high, Nezu along with Midnight and Aizawa went down to the detainment area of the school for students that are unmanageable and refuse to hold back. The last person who had to be put in these cells was easily two decades ago when Endeavor was walking the halls of UA. There, both teens sat in agitation after recovering from the R rated hero's quirk. “LET US OUT!” “You will be let out when the authorities arrive.” Aizawa coldly said this with Nezu walking up to both Bakugou and Camie who were in quirk restriction cuffs. “Times like these are where we as teachers dread. However, due to your actions Mr. Bakugou we have no choice.” He cleared his throat before speaking. “Due to the acts you have committed Katsuki Bakugou, you are hereby expelled from UA. You will also be charged with all the damages that have been done to school property as well as any personal belongings you have destroyed. Along with this, you will be charged with reckless endangerment, use of a quirk without a license, as well as disruption of a pro hero’s ability to do their job and some forms of assault. Since some students had been injured due to your little stunt.”

Bakugou could not believe this. He was not only kicked out, but also being charged with crimes. “We have also informed Shinketsu of this as well miss Utsushimi, they will discuss your punishment when you return to school after the weekend. What they did wish for me to inform you is that you may wish to begin looking into a new career along with a new school. That is, when you are free of the charges of illegal quirk use and disruption of pro hero work.” “ARE YOU KIDDING ME!? ME AND BAKUGOU TRY TO TAKE DOWN A VILLAIN THAT YOU LAME PROS LET SLIP THROUGH SECURITY, AND YOU’RE HATING ON US!?” Midnight had enough of this to step in. “Catalyst had the situation under control before you two stepped in! If you would’ve just let things be, we may have not needed to shut down the festival saying the situation was detained before it caused a problem! But because of the little stunt you and Bakugou had given, you had not only ruined that chance, but the hard work of every student that participated in the Culture Festival! Do you think that’s fair for them!?”

She bit her lip with Nezu getting a call. “The police are here. Midnight, could you please escort them down here.” She did as she was asked, having enough of talking to both the teenagers in the cell. To her, she respected the fact Izuku pulled in a lot of favors to help them and a little girl only to see them go up in smoke with all the hard work they gave. “Your parents were also informed of what had happened and are clearing out your dorm as we speak. I wish the both of you best of luck in your future endeavors.” Both teachers left with a few police bringing both Bakugou and Camie into the back of a police cruiser.
