It takes a few days when some one finally notices the change in class 1A. No, the change in their resident playboy.
Of course, it takes the classmate with the blunt mouth to voice their thoughts. "Has anyone else noticed there's something different about Midoriya?" Putting her finger on her chin trying to pinpoint what it is.
When they look to the strength enhanced quirk user talking with Mineta, they don't notice anything different aside from the fact their topic of choice surprisingly isn't rating girls of Yueei. In fact, for some reason Midoriya is talking about repenting and is splashing water on Bakugou starting a fight.
"Shitty Deku stop splashing water on me", the explosive teen yells as he chases the green haired boy, " And why the hell does that shit burn!"
"You must repent on your sins, I will pray for you" Midoriya yells as he jumps over desks to avoid an explosive fist in the face.
BY the end of class, they are unable to figure out what's different and leave it to try and solve it tomorrow, by asking his best friend.
The next day when Mineta walks into class, all 1A surrounds him asking for information on his best friend and how his date went. Mina asking for details, because something must've happened for his change in behavior. "Give us details Mineta" Uraraka begs.
The only reply heard from Mineta is a loud laugh and him telling them to wait for Midoriya to come to class, "You guys wouldn't believe me even if I told you". However, when he passes by Kirishima, the taller boy barely hears when he murmurs, "Man, now I know why they call her the Ace of 1B".
Wondering what exactly Mineta meant by that, they all wait in anticipation for the one in question to enter. Eventually when the one they've waited for finally arrives, Mineta words make sense not only to them but Kirishima who hear his whispered words.
When they turn their heads to see their friend at the doors of 1A and address his changes in the past week they find it difficult to do. Turning to look at the cause, they see their classmate Midoriya and 1B Ibara Shiozaki standing at the entrance causing a light to shine brightly on both, causing some confusion as to why the light is on Midoriya, Ibara makes sense, but Midoriya not so much.
"Gah too bright, the pureness radiating off of them, it burns" Kaminari yelps.
"Midoriya? Is that really you?" Tokoyami asks blinded by the light shining on the two.
"Indeed, brethren Tokoyami" Midoriya says head bowed, hands clasped together, confusing everyone in the room, except the one next to him.
"What the hell happened to Midoriya?" Tsu asks, referring to the Midoriya standing in front of them who is wearing his shirt tucked in, has his U.A. tie on, all his shirt buttons buttoned up, a belt to hold up his formerly saggy pants and- "Oh my god is Midoriya sporting a man bun!" Mina shouts surprised he combed his hair.
"I get the bright light shining on Vine girl, but why Deku" Bakugou gets out pissed at the light not getting out of his face. "Seriously where the hell is this light coming from!" hands exploding looking for the source.
"I have cleansed Midoriya of all his sins." Ibara says before leaving Midoriya with a kiss on his cheek and on her way to class.
Leaving an even more surprised class behind when they see Midoriya blushing because he never blushes, in fact it's usually the other way around.
"What the hell happened at bible club?" Todoroki asks.
"AHAHAHA, TOLD YA THE VINE GIRL COULD PURIFY SHITTY DEKU, DAMN EXTRA IS SO PURE SHE COULD TURN THE EVILEST VILLAIN INTO A HERO!" cackling Bakugou falls to the floor pointing and laughing at Midoriya once he gets over the light issue.
"I have seen the errors of my ways and with the help of Ibara-Chan purified my sins" Midoriya replies as a light shine on him even brighter.
"Ahh get that light out of my face, seriously who the hell brought that back" Bakugou yells as he yet again gets blinded. Trying to pinpoint the cause he only sees Deku " Shitty Deku turn off that bright light, and FOR FUCKS SAKE, stop throwing water on me already."
"You're a sinner! Kacchan"
"Oh my god, we have our very own Ibara, green hair and all" Uraraka says to everyone as they watch Midoriya toss water from a glass onto their explosive friend. Causing everyone to gawk and nod their head in agreement, before Aizawa finally comes in and yells for everyone to sit down.
"Wait who are you-Midoriya?" Aizawa says, incredulous at the new look of his usual scrappy student "What the hell happened to yo- -Actually I don't care just sit down" secretly he does, he just doesn't want to admit it. He'll just listen through the grapevine for information about his problem child's reformation, so he knows who to thank. Midnight would probably have an idea since she loves to gossip. After that thought he continues with his lesson.
Later
"Thank you" a gravelly voice says.
"I'm sorry. What"
"I said thank you. You don't know how much I tried getting through to problem child and nothing happened" Bowing Aizawa continues "Just a week with you and Midoriya is coming back as a reformed angel, I mean yeah, he's talking about sinners and saints and is throwing holy water on Bakugou, a lot, but I digress. I just need to thank you because now he isn't getting into any actual trouble or being such a playboy." Standing up finally Aizawa stares at the angel of 1B only to see a small smile.
"What?"
"It's funny, all I did was tell Midoriya-kun's mother about his behavior after he asked me on a date and all the sudden, he promised to stop acting like such a lecher" chuckling Ibara continues "funny what a mothers scolding does to a boy's attitude. Everything else is probably just an act really, a cute one but an act nonetheless" she's says imagining her boyfriend throwing plain water at his friends and ranting about them being sinners. She didn't really do anything besides get him to dress more appropriately.
Eye twitching Aizawa starts to turn around, "I see, goodbye then". Taking a deep breath, he mutters the words he's been saying since the beginning of the year "Damn problem child."
"Promise you'll stop splashing your classmates with water"
Rubbing his unruly hair now released from his man bun, Midoriya relents and agrees to her terms. Hers being his girlfriend, Ibara Shiozaki. He really doesn't want to get withheld kisses from her or another scolding from his mother, so he decides to roll with it.
"Yeah, I promise to stop tossing water at Kacchan and preaching about sinners to my class" smiling when he finishes his statement, he goes in for a kiss only to be stopped by a thorny vine.
"Sorry, but no kisses for those who are sinners" the smirking vine user says as she walks away hips swaying along the path back to their dorms.
Mouth agape Izuku only thought is "Saint my ass, she's a god damn sinner herself, devil hidden under an angels disguise". As he reluctantly follows the bible president to take a cold shower whispering the same words repeatedly "god give me strength".
