Chapter 1: Pride
In the town known as Mustutafu, Japan. A young boy of four years old was swinging on a swing set at night, waiting for the sun to come up. His emerald green eyes scried the sky above him, and scanned the stars as they painted themselves on the indigo depths.
After an hour passed, the first rays of the sun began creeping across the sky, causing the boy to smile. The rays of the sun were something he adored greatly, as they made him feel powerful.
"... What're you doing out here in the cold?" A voice questioned, causing the boy to jump slightly as he turned and saw a young girl standing there. Though you wouldn't think she was a girl at first.
Red shorts, a purple shirt and sneakers, coupled with her spiky pomeranian blonde hair, red eyes and fierce expression gave her the appearance of a boy, or a tomboy at the very least.
"K-Kacchan!" The boy gasped in surprise as the girl sighed, sitting in the swing next to him and placing a jacket on his shoulders.
"Jeez, Izuku, you shouldn't be out here dressed like that, you'll get sick." The blonde sighed. "Honestly, you can be so hopeless sometimes." She added, causing the boy to blush.
"Sorry, but you know how I like to be out here when the first rays of the sun show up." The now named Izuku said sheepishly.
"Well try not to catch a cold, alright?" The girl told him as the sun rose a bit more to where it was now visible–and next to her, Izuku started to change.
He was growing a bit of muscle, emphasis on a bit. This is a four year old boy, so him having the muscles of Arnold Schwartzenegger was just absurd. The muscles he did grow were fairly small.
"... Have I told you how beautiful you are, Katsumi?" The boy said, not looking at the sun, but rather the girl beside him, whose blonde hair seemed to sparkle in the morning light, as if he were looking at the sun.
"Whaddya goin' on about?" Katsumi questioned, blushing a light pink as Izuku cleared his throat.
"And so the lion shrugged off his mane, to sit in a field so very plain. 'Here I shall stay' His laugh was so hearty. 'So the beautiful sun's rays can bathe my body." He recited a hand on his chest… Only to become horrified when the girl began to struggle to hold in her laughter.
"A-Are you f-f-for real?!" She snickered. "Your poems haven't gotten any better." She chuckled.
"What? 'Tis true!" The boy whined. "You are like the sun itself to me, Katsumi. You always have been." He added.
"Well, maybe you'll get better at making that more clear with better poetry in the future." Katsumi chuckled, and it was clear that she was more dense than a neutron star.
Yes, that's right, the girl is the one who's dense this time. At least for now.
This caused Izuku to look at her with utter bafflement, before sinking. "My poems aren't that bad, are they?" He questioned, slightly deflated.
"They really are." Katsumi admitted in a blunt manner. But as the boy's face darkened in despair, her cheeks flushed rosie again as she leaned into his ear. "I'd still listen to them, though." She whispered, before playfully nibbling on said ear. "Om!" She grinned.
That got a surprised reaction out of the boy, and he would forever deny that he jumped out of his swing and fell face first into the ground.
This caused Katsumi to start belly laughing so hard that she fell out of her swing next to him, hugging the green haired boy close to her and smiling at him.
"You're such a dork sometimes." She sighed before kissing his forehead. "But you're my dork." She added, causing the boy to blush again.
(Timeskip)
Eleven Years later, Izuku Midoriya was now walking to school one morning. But something was… Different about him.
In comparison to when he was a child, he had the muscles of an up and coming bodybuilder. He actually had to get custom clothes so that he wouldn't have to replace them on the regular.
Additionally, he had since gotten a red Lion tattoo on his back, which he got to help him own the image he'd cultivated for himself over the years. That of the Lion Sin, the Sin of Pride. That was his new persona going into adolescence.
Right now, he was wearing a Japanese middle school uniform that was tailored to grow with him as his quirk's power increased.
Speaking of said quirk, it was known as Sunshine. Named after the magical power of the Goddess Race of the same name, this power caused the boy to grow in stature and power as the day went on–peaking for about a minute at noon–and then decreasing as the night came. In addition, it also allowed him to use the various attributes of the sun as powerful attacks, create blistering heat just by applying it to his body heat, and even create small suns in the palm of his hand.
As long as the sun was out, then he was essentially superhuman even by the standards of the quirk based society he lived in–Neigh invincible, in fact.
Izuku continued to make his way to school when he came upon a giant super villain who was causing mayhem at the train station. This caused the Sin of Pride to scoff in annoyance at the inconvenience before him.
"The nerve of some people." He remarked aloud.
"Tell me about it." One of the other bystanders commented in agreement.
"What's the story?" A man questioned.
"Just some amatuer, stole someone's bag and got himself cornered." Another shrugged.
"A quirk like that and he's just a common thief." The other man sighed as Izuku moved past them.
"Such pointless frivolity." He scoffed, unimpressed by the fight and the commentary around it.
Then a few heroes started getting involved, but Izuku wasn't really impressed. Death Arms, Backdraft and Kamui Woods didn't really paint a good image in his eyes, and they talked too much mid fight. Was there a point to the cheesy lines they spewed at times?
"Lesser words, greater impact." He mused, getting the attention of a man next to him. "Idle threats and verbose speech only serves to waste precious time in battle." He added, arms crossed.
"Somebody's not a fan of idle chatter, I see." A man with fins on his face noted.
"It bores me." The green haired teen told him in reply as Woods tried to use his ultimate move.
"Canyon Cannon!" A female voice yelled as a giant woman came flying out of nowhere and kicking the Villain down.
Then she started posing for the camera, and Izuku stopped paying attention to her after that. He just opted to get on his train and head to school to get away from the brain summit that was happening around him.
(Later)
"Utter nonsense…" He sighed as he made his way inside his school to get to class.
"There you are." A voice said in front of him.
"Hm?" The green haired teen uttered as he looked in front of him and saw Katsumi standing there.
She had certainly filled out over the years. She had the beginnings of a womanly figure with a bust and an ass that seemed to match each other well, and she had a fair bit of muscle to her as well. At present, she was wearing the Japanese girl's uniform.
"You kept me waiting." The blonde stated, tapping her foot. "You know I hate waiting." She added.
"An amateur villain held up my train. You know how moronic people can be." Izuku told her simply in reply, taking her hand and kissing it. "But I apologize for making you wait all the same, milady." He told her, causing the girl to blush,
"Sh-Shut up, you charmer." The blonde muttered. At least she wasn't as dense as she was when she was younger.
Izuku only chuckled as they entered class together where their teacher spoke about how they needed to start considering what they wanted to do with their lives, but that everyone only wanted to go into the hero track.
"Hmph! Hey Teach!" Katsumi called. "Don't lump me in with the rest of these losers! I'm the real deal but they'd only be lucky enough to get in as sidekicks to some busted D-Listers! Ha!" She continued with a scoff.
"You think you're better than us, Katsumi?!" One student yelled as everyone booed her.
"LET'S GO I'LL TAKE YOU ALL ON!" The girl retorted, before everyone stopped and covered their faces as Izuku silenced them by creating a small sun. "Hey." She said, looking at the boy. "Put that light out, will ya? You'll burn the school down." She told him. "Besides, I don't need you to fight my battles for me. I can handle myself." She added.
Izuku let out a sigh as he closed his eyes and snuffed out the sun. "As you wish." He nodded simply.
"Hmmm, you have impressive test results. Maybe you will get into UA." Their teacher mused.
"She's going for the national school?" A girl asked.
"That place has a .2% acceptance rate! It's impossible to get in!" Another student added.
"That's why it's the only place worthy of me!" Katsumi nodded as standing on her desk. "I'll be more popular than All Might himself, and be the richest hero of all time! Everyone will know who I am, and it all starts at UA!" She exclaimed.
"Oh right, Midoriya, you're trying out for UA, too." Their teacher mused.
That caused Katsumi to freeze before she looked back at the viridian haired Lion Sin, who was unperturbed by the sudden attention.
"Indeed I am, and nothing can stop me from entering." Izuku nodded. "And I do mean nothing." He added, looking Katsumi in the eye, and he could tell she knew he was serious.
This caused the blonde to pout as she blushed. "Had to steal my fire, didn't you?" She pouted.
"All's fair in love and war, milady. You know that." He chuckled.
(Later)
After classes were done for the day, Izuku was writing some poetry in a notebook. Specifically, it was about the various heroes he knew of.
Though as he was writing a fresh new poem in his book, he soon stopped when he was pinned to the back wall by Katsumi while everyone left.
"Katsumi…?" The Sin of Pride asked as he looked down, and saw a serious Katsumi looking up at him.
"The koi pond out back. Meet me there in five minutes." The girl told him. "Don't make me wait." She warned.
Izuku only nodded as he closed his notebook. "As you wish." He replied.
After taking a moment to pack up his stuff, he went to the koi pond and found his childhood sweetheart waiting for him.
"You didn't make me wait this time. Good." She nodded.
"But of course." The boy nodded, bowing to her. "You wished to see me?" He asked.
"Yeah." The blonde nodded, her foot tapping a bit as she gathered herself and got her thoughts together. "… You know what? Fuck it." She sighed, deciding to skip the semantics and went straight for the jugular by grabbing Izuku by the collar and pulling him down to her level and kissing him hard on the lips.
Izuku, to his credit, hid his surprise well and found enough of his nerve to kiss back as he held Katsumi flush against himself. He silently admitted that her body felt good.
As the two pulled back, the blonde snaked her arms around the boy's neck and hung something about it for a few seconds before…
Click
The sound of a latch being fastened could be heard as Katsumi slipped a yellow choker with a silver Lion charm on it around the boy's neck.
"Hm?" The Lion Sin hummed as he glanced down at his neck as best he could.
"You're mine now. No one else has a claim to you, and they never will." The pomeranian haired girl told him firmly, pulling him down by said collar. "If they try anything, they'll have to get through me!" She added with a growl.
"So I am to be your pet, is that it?" The Lion Sin questioned, as if unamused by the prospect that the woman he professed to love was willing to drag him down.
"Pet? … Maybe. I'm just marking my territory, otherwise." The red eyed girl grinned in reply with a shrug. She then looked at him with more sincere eyes. "I just want you all to myself, is that so wrong?" She asked, as if trying to tell him that she liked him without having to say it out loud–which honestly made sense to the boy.
"... No, it's not wrong." He admitted in reply before scooping her up in his arms and kissing her again. "For I wish to have your love all to myself as well." He nodded, pulling back.
"Me too." Katsumi smiled, resting her head on his chest.
(Later)
After parting ways for the time being, Izuku was heading through a tunnel under an overpass to get home. He wouldn't admit it, but he was feeling rather good about himself now that he had Katsumi as his girlfriend.
Or was it lover? He honestly wasn't sure what title suited his beloved lady more. It was truly vexing, he had to admit.
"Oh finest wine, distilled from the ripest grapes and sweet–No. No, no, no. Too bland, overdone. Needs to be better." He mused, trying to write a poem extolling the feelings he was experiencing at that moment–of his love finally fulfilled.
"I recommend not saying anything." A voice that sounded like it was underwater interjected from behind him causing the Lion Sin to turn around and see a living mass of sludge.
"Do you mind? I am trying to write a poem." The Sin of Pride deadpanned as he conjured a sun in his palm. "Cruel Sun." He intoned.
"Oh cra–!" Was all he could say before the sun was thrown at him, causing him to boil from the heat before he exploded when the sun impacted him.
"Ah, finally, I can hear myself think again." Izuku sighed as he looked down at his notebook. "Hmmm, perhaps instead of a prose poem, I could try a Haiku? Shorter, less words. Could have a better impact." He mused, stroking his chin. As he was pondering this conundrum, the manhole cover from before was suddenly sent into the air. "Oh, now what?" He groaned, turning around.
"There's no need to–... Huh?" A booming voice started as they leapt out of the manhole before taking stock of the situation. "Apparently I'm late." He noted.
"Oh, hello there, All Might." Izuku nodded upon recognizing who it was. Honestly, All Might felt like the only competent hero in the field right now. "I was just trying to figure out a poem when this sludge based ruffian interrupted the process." He explained.
"... Ah." The Symbol of Peace nodded as he gathered the criminal up. "A poem, you say? What about?" He questioned.
"It's mostly just me trying to figure out the style. Prose is out, and I'm considering Haiku." The Lion Sin replied, contemplating what style to use.
"I see." The man nodded as they came out of the tunnel. "Young man, what is your name?" He asked.
"Ah, apologies." Izuku nodded as he bowed respectfully, as only All Might was the one he'd willingly bow to. "I am an aspiring hero." He began, before pointing to the sun. "But I am also the one who stands at the pinnacle of all Quirks." He continued. "I am named after one of the Seven Deadly Sins, the Sin of Pride." He elaborated proudly. "And my name is Lion Sin Izuku." He added.
"That's quite the claim, saying that you stand at the top of all quirks." The man noted. "And you named yourself after one of the Seven Deadly Sins? Well, the pride you display makes that obvious." He added offhandedly.
"A bold claim that I know to be fact." The teen replied. "I rarely acknowledge anyone weaker than myself and even less whom I consider equals." He continued. "But you are one of the very few exceptions, All MIght." He added.
"Well, that's certainly interesting to hear." The blonde man noted before looking around at the sludge. "Could I get you to help me gather up this sludge? It actually makes up a villain I was chasing." He requested.
"You have saved many lives and inspired many others, including mine, so performing a simple task seems a meager way to repay you." Izuku mused before shrugging. "But a small gesture is better than none at all, I suppose." He shrugged.
"Wise words indeed." The man nodded in approval as they got to work.
(Later)
After Izuku helped All Might gather the villain up, the man began to get ready to leap away, when he noticed that the Lion Sin was doing the same.
"What are you doing?" The man asked.
"I'd like to have a word with you in a more private setting. This place is far from private." Izuku replied. "And don't worry, I can keep up." He added.
"Very well…" All Might nodded as they leapt away together, and landed on a nearby rooftop. "You were saying?" He asked.
"Before I ask my question, I believe I should explain to you what my quirk is." Izuku told him as he created a small sun in his hand. "It is called Sunshine, I believe you may already know the origins of the inspiration behind that name." He continued.
"Yes, the Arthurian legend is common in every corner of the world." The No. 1 hero nodded in reply.
"Then you must also know that my power increases as the sun rises into the air." Izuku deduced.
"And declines as it sets, leaving you vulnerable at night." The man nodded in understanding. "Why?" He wondered.
"I was curious, if you would grant me the honor of training my Night Time body." The boy explained. "I wish to become a powerful hero who can succeed you one day if need be. So I can think of no better mentor than yourself." He added. "You are the Symbol of Peace, after all. So you are the best choice by far." He concluded.
"A sensible request." All Might nodded, understanding fully why this teenager would make such a request. Before he could give an answer, steam started coming off of his body. "Oh no!" He gasped before he was engulfed in steam.
"All Might? Are you alright?" Izuku questioned as he approached the man. "Oh no…" He gasped in horror as the steam cleared.
Where a once buff man stood, a gaunt and lanky one took his place. It was honestly hard to compare the two very well.
"Well… This is awkward." The lanky man commented awkwardly.
"So I am not the only one with a weaker true form." Izuku mused as he sat down with the man. "How did this happen?" He questioned.
He got his answer in the form of the man lifting up his shirt and revealing the ugliest scar he's ever seen. It actually made the viridian haired Sin wince in phantom pain since the wound that made the scar actually looked seriously painful.
"Pretty nasty, right? This is the scar I got from a fight five years back." All Might explained. "I lost my whole stomach, so I had to receive a transplant earlier this year–meaning I'm just now starting to recover." He continued. "Add that I also have damaged lungs and it all adds up to mean I can only do hero work for three hours a day." He added.
"I can already tell that it wasn't Toxic Chainsaw. He hit you a few times, but those hits were never this severe." Izuku deduced. "This was from someone much worse, wasn't it?" He questioned.
"Indeed." All Might nodded. "But as you said, I am the Symbol of Peace, so I have to smile to hide the fear I feel inside. To put everyone at ease." He continued.
"Then you are far more courageous than I." Izuku admitted. "In my night time form, I am the exact opposite of what I am now. Small, frail, weak, timid, scared, controlled by my emotions." He listed, his face hardened. "All things I detest about myself." He added.
"More reason for me to help train that side of you." The man stated. "It's gonna take me a bit to whip up a schedule, though." He added with a sigh. "But I can tell you this: you're definitely hero material." He declared. "But you shouldn't detest your night side, it is a part of who you are. A softer side that I'm sure those who care about you love just as much as your current form." He added.
As he said this, Izuku's thoughts flashed back to Katsumi and how, when he was in his night form, she would always display a more dominant side towards him that she never showed to anyone else, doting on him and loving on him like a kitten.
How his mother would often dote on him as well.
It was kind of nice. All things considered.
"Perhaps I had the wrong idea for too long, in that case." He mused.
As he said this, however, there was a massive explosion that occurred in the distance, causing the two to get up, and for All Might to notice that the cap to the bottle they'd gathered the sludge villain in had been melted off.
"Oh no…!" The two gasped in unison before Izuku grabbed the man and leaped in the direction of the blast.
In the direction of the blast, a now free sludge villain now had one Katsumi Bakugo in his clutches, tendrils of slime slowly and thickly beginning to shove their way down the girl's throat, like she was deepthroating something.
She was trying to blast her way free, but all she ended up doing was cause unintentional collateral damage in her panic.
"LWT ME GO, YOU FWCKER!" She yelled, her voice muffled.
This was the sight that the Lion Sin came upon when he and All Might arrived on the scene, and the sight of this villain, this vermin daring to lay a hand on his Katsumi, his precious treasure, made his blood boil.
"Someone's going to wish they died!" He growled as he stalked forward, anger in his eyes. And as he did, he started letting his control slip.
See, he'd been holding back his power pretty much all day to avoid causing any unto damage to his middle school, so it halted his internal clock. When he did this, he could either store that day's power into the tattoo point on his back for a do or die emergency–Or, release it all at once to give himself a massive power boost in one go.
Guess which one he was using for this instance.
The sludge villain could feel his body boiling again, and that made him get distracted enough for his grip.
"Your audacity seems to know no limit, monster." The boy said as he stalked towards the creature, his power raging and melting everything he passed by–even burning away his clothes to reveal his Lion tattoo.
"What the? What the hell are you?" The creature gasped as Izuku stood nearly as tall as All Might now.
"I am the one who stands at the pinnacle of all quirks." Izuku began as he drove his fist into the creature's face, making his grip loosen again, before grabbing Katsumi. "The Sin of Pride, Lion Sin Izuku." He added as he pulled the blonde away. "And now I shall give you a single chance to spare your pathetic life." He told the sludge mass
"What?" The monster questioned.
"Apologize." Izuku began as he set his lover down while everyone around them took notice. "Apologize to me, that you came into my world." He added, raising a finger as a Cruel Sun formed. "I'll give you five seconds." He stated.
This show of power was extremely terrifying since being hit by a small star was nothing to scoff at. One hit at a high enough power level was bound to be lethal, and judging by the Cruel Sun on Izuku's fingertip… You can guess what the result would be.
"Time's up." The boy said, before he slammed the sun down on the creature, causing an explosion.
Everyone shielded their eyes from the brightness of the blast, and when it ceased, everyone looked and saw that the sludge villain had been thoroughly scattered due to the sun causing his body to boil and burst, sending him splattering all over the place.
"Hmph, inconvenience at its most." He sighed before he turned to Katsumi and helped her up. "Are you hurt, my dear?" He asked her, dusting her off.
"Y-Yeah… I am… Now…" The blonde panted, trying to catch her breath.
"You really must stop getting yourself into trouble, my love." The Lion Sin told her. "I can only do so much to be there to protect you." He added, cupping her cheek in his hand.
"Don't worry, I know." Katsumi breathed, finally getting a sufficient amount of oxygen in her lungs.
A moment later, some medics came by while Kamui Woods tried to berate Izuku for his destructive use of his quirk. Keyword being tried. The second they started trying to, he glowered over both of them with a glare on his face that shut them up.
"Did I ask for your opinion?" The Sin of Pride deadpanned as he glared Kamui Woods and Deatharms down, not intimidated in the slightest by the two men. "Neither of you did anything of substance in that situation, and I refuse to be scolded for doing something about it." He told them. "Now get out of my way!" He barked, pushing past the men before he took his leave from the scene, pointedly ignoring the reporters.
All Might watched the boy leave, and was quite surprised at just how prideful the teen was. Clearly, his nickname was no mere joke.
Still…
'I think I found the one.' He thought, watching Izuku's retreating form.
(Later)
Sighing, Izuku could feel his muscles start to relax as the sun began to go down that evening on his way home. But at the same time, the evening chill made the boy shiver as he no longer had his top clothes.
"Well this is rather annoying." He sighed, holding himself as he shivered while he walked before he heard the sound of running footsteps coming from behind him. Turning, he saw Katsumi looking ready to literally jump into his arms. "K-Kacchan?!" He exclaimed, his more timid side coming out.
"There you are, my little kitten." The blonde purred as she pulled him close to her by his new Lion pendant collar. "Did you miss me? Did you miss your mistress?" She questioned, caressing his hair as she held him to her D-Cup bosom.
"Y-Yes…" The boy admitted, relishing in her warmth. "I'm also really cold." He added.
"Aw, you poor baby." Katsumi cooed as she opened her school coat and pulled him into a hug again, enclosing him inside her uniform against her chest.
They spent a good bit in silence, Katsumi keeping her favorite kitten warm while Izuku relished in her presence.
"I just wanted to thank you for helping me." The blonde told him. "But really, you didn't have to. I would have gotten free, eventually." She added with an eye roll, only for Izuku to bury his head into her chest.
"I know, but–I… I didn't want to lose you." The boy said, his eyes beginning to water as the emotions he bottled up during the day as Daytime Izuku finally were set free. "I couldn't bear the idea of losing you, Kacchan." He whimpered, tears soaking into the girl's shirt. "I love you." He added softly, almost in a whisper–which was partially muffled by the girl's breasts.
Katsumi didn't hear it as she rubbed her boyfriend's hair, the softness of it setting her at ease. But she didn't need to hear it, she knew what he said, she could feel it.
"Hey." The blonde said. "Izuku, look at me." She told him as she raised his head up. "You will never lose me, ever. I promise you that." She continued. "I will always be there for you, always by your side." She declared, looking him dead in the eyes. "And I will always, always love you. No matter what." She added firmly, cupping his cheeks in both hands. "Because you are mine, Izuku Midoriya, mine and mine alone. No one will ever be able to love you more than me." She concluded.
"... Thank you." The boy sighed as he let his head be pulled into the crook of his girlfriend's neck.
"Thank you…?" Katsumi questioned expectantly.
"T-Thank you, mistress." The boy gulped as she had him look at her again.
"Good boy." She smiled before kissing him with her tongue, and—rather easily—quickly won a battle of the tongues against him, causing the boy to moan as he was dominated by his mistress.
Then the explosive girl pinned her pet against a wall, pinning his arms above his head as she kept dominating him. Izuku didn't protest, he couldn't—and even if he could—he wouldn't.
His daytime self would never admit this, but he loved being dominated, he loved how Katsumi treated him, how she showed her love for him. It all made him feel so good.
Unbeknownst to them, All Might had just come around the corner and was about to say something when he saw what was happening. The sight made him wiseley keep his mouth shut and wait for them to finish.
As the two separated, the pomeranian then took advantage of Izuku's moment of vulnerability–since she still had his arms pinned above his head–and proceeded to make several love bites and hickeys all over his neck, collar bone and shoulders–fully and visibly marking her territory. All the while Izuku couldn't stop himself from moaning her name.
When Katsumi was done, she pulled back and looked her pet in his eyes.
"Mine." She whispered possessively.
"Y-Yes." Izuku gulped as she got up and let him go free, but not before giving him her jacket.
"I'll see you tomorrow." She told him, kissing his cheek. "Bye, I love you." She cooed as she walked away.
Izuku couldn't stop the blissful sigh that escaped his lips as he turned to head home.. Which was when he finally noticed the Symbol of Peace standing there, looking away.
There was a very awkward silence before Izuku spoke up.
"How much did you see and hear?" He questioned.
"Let's just say enough and leave it at that." The man replied awkwardly before he deflated. "Apologies, I would have come back later, but I had something I wanted to discuss with you." He explained, wiping his mouth. "The true you." He added.
"The true me?" Izuku questioned, confused.
"That's right." The man nodded in reply. "You see, we actually have a bit in common: Both of us have forms that hide the fear inside, and serve as the faces people see in the spotlight while few know what we look like outside of that." He continued.
"Yeah… I guess we do." The boy nodded. "So… What did you want to talk about?" He asked.
"I wanted to talk to you about what you said before." All Might explained. "You said you wanted to become a great hero, one who could take my place if need be." He continued. "Well, look no further." He told the boy. "For I deem you worthy of my power–it is yours to inherit." He added.
"... Inherit?" The Lion Sin asked in confusion.
So begins the story of the Lion Sin of Pride.
Dragon Emperor0: Hello, Dear readers! Hello and welcome to another new story that we have finally decided to publish after finally managing to get it planned. But, after seeing how successful our approaches were, we decided it'd be best to just use an already working formula than just make one from scratch for this one story. So, here it is: Lion Sin.
ThermalsniperN7: We even decided to take the fem!Katsuki route this time since we've been looking for an excuse. We tried it in Wrath of the Pharaoh, but then we changed our tune, so that's out.
Dragon Emperor0: Plus, with how successful Boar Sin's looking to be, it seemed like a good concept to explore—that being the idea of fem!Katsuki here (Katsumi) being your classic loving and doting Dom girlfriend, with Izuku as her timid and equally loving Sub boyfriend. And as you can see, the self proclaimed Sin of Pride loves the idea of being dominated, so long as it's by his Dom girlfriend. Heh, the irony.
ThermalsniperN7: I hear that, and Izuku is essentially similar to All Might this time around in the fact they both have "true forms" when they aren't surrounded by a bajillion people. And yeah, while Sunshine is already OP, it only really works while the sun is in the sky, so getting OFA works for when the moon is out.
Dragon Emperor0: Aka any fight that takes place during nighttime. Like the fight with Stain, for example.
ThermalsniperN7: Precisely. Though what happens when Katsumi finds out what the full context of the deal is, that could be a bit of a concern.
Dragon Emperor0: That is true. And as you can probably see, in this story, there is no waiting until later for Katsumi and Izuku to get together. They know what they want and when they want it and will show it to the world if they want to. Though it does make me wonder how the class will react to how Katsumi is basically able to dominate and turn the Lion Sin of Pride into a little kitten who is totally puddy in her hands.
ThermalsniperN7: I imagine that there's gonna be a ton of teasing aimed in Izuku's direction during the night… And if everyone knows what's best for 'em, they'll keep their mouths shut for their own safety while the sun's up. We both know how Izuku's gonna take that teasing during the day.
Dragon Emperor0: Yep. Also, we may actually take inspiration from a slice of life anime I got into last summer called Shikimori isn't just a cutie for Nighttime Izuku and Katsumi's relationship. Since I'm kinda seeing a few similarities already… Other than that, I'm excited to finally be starting this story.
ThermalsniperN7: We did have an idea for Izuku to be with Ibara originally due to the relationship between plants and the sun, but our interest in that died overtime. Anyway, see you next time.
