The sun was setting fast after Class 1-A got back from the Battle Trial under All Might the Symbol of Peace himself. Cecelia Miyamoto headed off for home after that school was over. She was teamed up with Izuku Midoriya in a Hero Team against Katsuki Bakugou and Tenya Iida in a Villain Team. It went down like this:
Cecelia conjured her trusted weapon called the Redemption Keyblade And got in front. Midoriya said in awe while following behind her: "Whoa! How did you do that?" She said to him while looking around the corridors: "It's from magic that I am born with, Midoriya. I did say that I'm Quirkless but is gifted with a different source of magic. But so far, Bakugou didn't seem to believe me. So...what I'm thinking is going up against him. As for Iida...since he's fastest on his feet, I can put up a spell on you to give you the edge and possibly getting you to capture the weapon as well. Do you trust me?" Midoriya nodded and said, "I do trust you. Despite that we only met once, I feel that I should trust you." She began to close her eyes and focus on gathering magic into the Keyblade. From there, she said this spell before releasing its light onto him: "Dragon Guidance!" A dragon's growl is low and it's in its own ethereal form of a majestic dragon entered into his body. Cecelia explained to him of this: "I used the spell called Dragon Guidance. Basically, it would act like a secondary instinct on the defense for you in battle if you are in a disadvantage." Some time passes by as she pulled him back for a reason. That's when there is a huge explosion from the narrow corner on the right is sent right at them! Cecelia puts the Redemption Keyblade in front and conjured a crystallized magic barrier to deflect the attack and shouted: "Midoriya! Go for it!" Bakugou was just about to attack Midoriya but got thrown back when Cecelia somehow got in front of him and executed a powerful Tornado Kick of which her right foot brings out a rather strong spark of white lightning. Bakugou had to use his forearms on the defense as he got blown backwards by a few feet while skidding across the grounds. He looked up and his eyes widened a bit. Her own Hero Costume that's modified from its original design as a training outfit made her look like a mysterious and sultry yet skilled female ninja by the looks of it on her. He got up on his feet and watched as she "puts away" the Redemption Keyblade and took in a martial arts stance involving Kung Fu. Soon, it got to where his punches and her palm strikes are exchanged side to side. At first, it looked like neither of them can land a single blow. But as she pulled herself back. this is when he noticed the emitting amount of lightning all around her body and thought to himself: "Damn it! How did she gather that much of lightning without me noticing anything?!" Executing the strong side kick, this is when she stood on her right foot and released the high speed barrage of kicks that hits with such force as well as shocking Bakugou with lightning all over his body. He didn't have much of the time to block as she would switch from one leg to the other with continuous kicks to deliver lightning hits until she sent him flying backwards with the Reverse Back Kick.
Meanwhile, Midoriya finds the "weapon" but is confronted by Iida. Tenya Iida is known for his Engine Gear Quirk as well as his keen intelligence and quite the durability and enhanced stamina. Midoriya thought to himself: "Alright...if Cecelia's spell is going to help me..maybe now might be a good time." Iida speeds up and he's about to do a knock out kick. But as if something is signaling out a warning, that's when Midoriya was "told" to pull back his right leg and perform the Tornado Kick while using ten percent of his power. This execution of an attack not only allowed Midoriya to dodge Iida's kick, but it enabled him to counter with his own of which hits Iida squarely in the chest to send him flying into two stone pillars. The room that they're in still hold on much and Midoriya hurried over to get to the weapon. Iida tries to get up, but he couldn't move. It's as if he is temporarily paralyzed. From the earpiece to communicate, he said to Bakugou who is still fighting against Cecelia: "Bakugou! Midoriya is on his way to the weapon!" Bakugou shouted angrily: "What?! That damn Deku should've been easy for even you to take down!" Cecelia then said this to him: "That's because I have enhanced Midoriya with a spell that allows him to see through his opponent's strategy and rely on the best of flexes while even tapping into his power." Bakugou stared at her and scoffed: "Hah! Is that so? Well then! If your magic is so damn powerful, why don't you show me with just one of your damn spells to overpower me?" She asked him after seeing that it's only been five minutes since the match starts for a full hour: "You're sure you want to do that? I'm not saying that you're weak. I'm only saying that you might be in over your head. Then again, real experiences to be the best takes risks." He grinned and said, "I somehow knew you were going to say that. And I don't back down from a challenge." She nodded and magically brought out the Redemption Keyblade as she jumped back to be about four feet away from him in front. She then said this to him as she wields her Keyblade like a sword: "I guess your bracers on your forearms aren't just for show. They're used to store up a vast aount of your sweat for your Quirk, aren't they?" He scoffed as he got in position: "Guess I was wrong. You are smarter than I thought. You may have the smarts, but do you have the strength to beat me down? Once I pull this pin, it'll release a bigger explosion in one big blast!" All Might calls out from one of the speakers through the entire building: "You'll kill her!" Cecelia proclaimed as she has gathered just enough of her magic: "I'll be just fine! Don't worry about me!"
She then shouted as she strikes her Redemption Keyblade across like a back hand attempt: "Full Counter!"Bakugou's eyes widened as she not only reflects back his entire blast but doubled it up with twice the power and twice the damage! A huge explosion occurred of which almost destroyed the entire building from the inside out. But as the smoke clears up, Bakugou was bracing himself for the worse but nothing came of it. He opened his eyes and looked down to see that his injuries from before are healing up. When he looks around, he sees this beautiful light-green barrier formed by Cecelia as she spoke: "Pollen Garden. It's a barrier formed by fairies of which protects the targets and allies from outside attacks while healing them as long as they stay inside." Bakugou growled: "First, you were beating me down. Now, you're helping me. What sort of game that you're playing?" She answered while shaking her head: "It's not a game, Bakugou. Whether it's just practice or for real, you would have gotten hurt badly or even killed because the Full Counter threw back your attack and doubled its strength." His mind raced with this thought: "If what she said is true...if I was to go all out and she used that technique on me...will that mean...I could've been killed by my own attack?!" He's snapped back into reality when All Might announced from all around: "Young Midoriya has captured the weapon! The Hero Team wins!"
Cecelia was at the family house that she's taking care of while her parents are on their Pro Hero missions. Out of nowhere, the Redemption Keyblade appeared and began to glow. From what her mother would tell her, the Redemption Keyblade will do that if it senses a world that needs to be saved. Having a feeling that it might take up to three days, she packs up a sizable luggage, left a note on the dining room table of where she might be, and allowed the Keyblade take her to wherever she's going to go.
