Daemon of Wrath: Thanks for agreeing. You did a good job of giving ideas for the name, and yes, it does make sense. Also, it won't be the only time Izuku turns his shadow soldier as weapons, so buckle up. As for how the others react to the Trinity's ability, you can assure that All Might won't overreact like other fics. Gang Orca visits him in early chapters to explains and hanging out with Naomasa did help him get introduced to the world of Dungeons and Magic. For Kamish, no spoilers. And lastly, you do realize that Beru counts as a child even with his attitude, right? I mean, he hatches right at the Jeju Island Arc and he died after only hatch for less than a day and revived.

AnimeFan13579: True. And yup, I got plans for Kuro.

Roppongi, Minato

Tokyo, Japan

"Whoa!!"

Izuku, Eijirou, and Ochako were in awe at the scenery they were seeing right now. They did once visit Tokyo, but back then, they were merely visiting the shopping mall for necessities and they bought so many items that they were unable to go sightseeing.

Now that they're free, they can see the city itself. Roppongi has shown to be completely different from the normal place they used to visit. While Musutafu was full of traffic due to constant attacks of Heroes and Villains, with civilians crowding the street just to watch, Roppongi seems to be more focused on the high number of populations instead of the constant villain attacks.

They were able to see how much the traffic is much better in the city. There are a lot of people in the crowd, but it wasn't as suffocating as back when Izuku watched villains attack. Izuku also notices the higher amount of vehicles running on the street, ranging from cars to electric bikes.

Eijirou excitedly pulls Izuku's shoulder and points in a direction, showing heroes patrolling the area and even helping to guide the traffic. Izuku lit up, smiling at the scene. He was glad that there are heroes who are willing to do menial tasks, even if it isn't as action-thrilling as fighting villains.

"This place is amazing!" Ochako exclaims as she rushes towards a store full of women's clothes; stars appear in her eyes while drool escapes her mouth. "Oh, I want to buy some of these so badly!!!"

"Easy there, Ocha," Izuku says with a laugh. "We just got here, and we got times, so we can buy it later."

"For the record, you may be my bro, but I ain't helping you carry your girlfriend's groceries. So, good luck suffering." Eijirou hisses at Izuku's ears as Izuku merely stares at his best friend.

"And for the record, she's not my girlfriend," Izuku says in an annoyed tone. "And also, you seem to forget that I have inventory. You forgot that you're the only one suffering through our last shopping spree with Ocha and my mom."

"No need to fucking remind me," Eijirou says with an eye twitch. He still remembers how he suffered from carrying a portion of the woman's groceries back then. Izuku could've helped store it in his inventory, but instead of helping, he chooses to let him suffer. "You could've helped, you know."

"It's training if you plan to have a girlfriend in the future," Izuku says with a teasing grin, causing a tick mark to pop out of Eijirou's forehead.

"You did that because I keep teasing you about your relationship, aren't you?" Eijirou asks.

"I have no clue what you're implying." Izuku says in a faux innocent tone. Eijirou merely stares at him with deadpan expression. "Anyways, so you guys want to visit the city first or you all want just go straight to the dungeon?"

"The city!!" Ochako exclaims excitedly as Eijirou nods.

"Yeah, the dungeon isn't going anywhere. Judging from the dungeon's rank, we might be in the dungeon for a while, so why not look around the city? Maybe we could get something to eat?" Eijirou suggests as Ochako shakes excitedly.

"I want to eat mochi!!" Ochako exclaims as Izuku chuckles at the scene.

"Fine, let us enjoy our day before we tackle whatever we're gonna face in the dungeon," Izuku says as they all cheer. Izuku let out a soft smile before the three of them ran off, enjoying the day as much as possible.

Meanwhile

"Stop right there!!"

A green sludge with eyes and mouth can be seen rushing through the alleyway in panic; its breath is heavy, and its body shakes violently. The sludge frantically looks around before it slips into a narrow space as a hero lands nearby, sees the scene, and curses the sludge for being so slippery.

'Shit, I barely shake him off my back.' The sludge thought anxiously. This sludge is the same Sludge Villain that was attacking the Musutafu, getting chased by All Might, and took Bakugou hostage while also causing permanent damage to the boy's lungs.

He did end up being captured by All Might in the end, but the stupidity of the police has no bounds as they didn't properly contain the villains, believing that the villain would be too scared to escape after getting beaten by All Might. This allows the villain to escape from their prison and go into hiding.

But, it seems hiding is far more difficult than it looks. His escape made the HPSC increase the level of its threat and made people even more cautious of him. The majority of heroes took this as a challenge to capture a villain that not only escapes All Might's clutch once but twice, believing that it would increase their frames.

So, in short, the police's stupidity grants the villain a chance to escape. And his escape made him being hunted down like dogs. Yeah, it wasn't a good month for the Sludge Villain.

'I don't get why heroes won't stop hunting me! I get I escaped from prison, but wasn't this a bit too much!?! It's been 9 months and they still hunt me with the same ferocity as before!' It seems that the Sludge Villain didn't get the memo on the day of his escape from the prison. But, given that he's been focusing on hiding and running away, it's understandable.

'I need to get out of here!' The Sludge Villain immediately rushes out of the other side of the narrow space, but his huge body catches everyone's attention, even the police and heroes. The villain flinches when he hears a shout and rushes off with no hesitation.

"Leave me alone already!!!" The Sludge Villain roars as he rushes through the street, forcing the majority of the citizens to move out of the way in fear. The Sludge Villain grits his teeth out of frustration before he notices a group of kids walking on the street. Remembering his experience, he decided to take the kids as hostages to keep the police and heroes from capturing him.

"Sorry, kiddos! Nothing personal!" The Sludge Villain roars before he opens his maws widely, trying to get the kids. Sadly, it was the biggest mistake he had ever made in his not-so-short villain career.

The group of kids aren't just run-of-the-mill kids you find in the street. They are the Trinity itself, trying to enjoy their time in the new city. Now that a villain decided to ruin their fun, they are surely pissed.

As Izuku turned his head towards the Sludge Villain, said villain felt shivers down his non-existent spine, and they grew as Izuku's eyes glowed. In a matter of a second, the villain felt a crushing force hit from above and squash him like a bug. He starts to cough in pain, blood escapes from his mouth as a hand-shaped crater appears around his squashed body.

"So, you're the villain that not only causes so much trouble for All Might but also permanently injures my former childhood friend," Izuku says as the Sludge Villain lets out a pitiful whimper, unable to move. "And what a surprise, to think I'll encounter you in this city."

The Sludge Villain felt his life flash in his eyes, tears escaping from his eyes. Of all the humans he has ever encountered, Izuku is the scariest one he has ever encountered, even more than All Might, which made him scream like a little girl. The boy's presence alone made him relive his infanthood full of cries and whimpers. Unable to handle the terrifying presence, the villain faints.

The Trinity stares at the villain, blinking owlishly as they watch the villain faint. They heard a loud hiss and started to squint in disgust. Izuku immediately deactivates his [Dominator's Touch] and moves away as he sees a yellow puddle forming under the villain.

"D-did that guy just piss his pants!?" Ochako exclaims in disbelief.

"Apparently, he just did..." Eijirou mutters in surprise.

"This is the villain that everyone's been anxious about?" Izuku mutters in disappointment. For a villain who manages to escape All Might's clutches and hurts his former childhood friend, who is by no means weak, it was very underwhelming.

"Why do you sound so disappointed?" Eijirou deadpanned.

"With all the news making him sound so dangerous, I thought he would be more..." Izuku trails off, unable to finish the sentence.

"Living up to his reputation?" Ochako asks as Izuku nods. "Yeah, I get you."

"When you put it that way, yeah, he's disappointing..." Eijirou mutters.

"Halt! You three!" The trio turns to see a random hero none of them bother to know points at them while snarling. "You kids are under arrest for illegal usage of your quirk!"

"I'm afraid that won't be necessary!" Everyone turns towards the source of the voice and gasps. It was All Might in his full glory, smiling brightly at everyone.

"A-All Might..." The hero mutters in fear as All Might places his hand on the man's shoulder.

"Accusing children of illegal Quirk usages, although it was clear they were merely defending themselves, was too much. I suggest you stop before you do more damage." All Might exclaims with a hint of edge in his voice, causing the hero to whimper and run off. All Might turn to face the kids. "Are you kids alright?"

"Yes, All Might," Izuku says excitedly. He may no longer be as excited as his old self when meeting heroes, especially since he has worked with some, but All Might was his idol for years, so his admiration towards the man is still there.

"We're fine," Ochako says in a similar level of excitement, while Eijirou nods rapidly with a large smile.

"I'm glad you are!" All Might pause before looking at the kids. "You three wouldn't be Izuku Midoriya, Eijirou Kirishima, and Ochako Uraraka, right?" His question causes the Trinity to gasp.

"H-how do you know our name!?" Izuku asks, a hint of nervousness in his tone.

"Well, Naomasa talks about you three every time we meet!" All Might exclaims as the Trinity blinks owlishly hearing that.

"Naomasa? You mean Tsukauchi Naomasa, the plain-looking employee." The Trinity asks as All Might lets out a cough to hide his snorts before he nods.

"Y-yes...the p-plain-looking employee..." All Might says shakily, trying not to laugh. "A-anyways, perhaps we could talk. I heard from him that you want to visit Might Tower."

"Wait, you allow us to enter, just like that?" Izuku didn't want to just look at the gift horse in the mouth, but this was just too easy for them, so he couldn't help but be a bit suspicious.

"Of course! Besides, I know about the... 'other stuff'..." All Might whispered the last part while making a magic hand gesture, causing them to stiffen before looking at each other.

Later

Might Tower

"So, 10 months ago, you and Naomasa tried to investigate what caused my injuries and were provided answers by Gang Orca?"

All Might and the Trinity can be seen entering the Might Tower as All Might nods at Izuku's question.

"Indeed, and I have to say, I was a bit skeptical when I first heard it. I mean, magic? It's not something people would've thought these day." All Might says as the trio nods in agreement. If they were in All Might's shoes, they would be skeptical as well.

"So, what changes your mind?" Eijirou asks.

"Thinking about the Dungeon Break happens near the Galewind Agency." All Might answers while looking at his hands. "I remember facing those monsters, destroying each one of them alongside fellow heroes. When the large one appears, I try to finish the fight as soon as possible, but my quirk does not affect them."

The revelation surprised the Trinity except Izuku, not expecting the Number One hero to be able to attack the monster. But they think again and it does make sense. Quirks could still affect normal monsters but when facing a boss, a monster with a hforh aptitude of magic, quirks aren't effective towards them. Ochako was the one who experience it herself during her first visit on the dungeon.

"And I saw something shocking, a broken blade, tossed from a distance, easily pierce through the monster like tearing through a wet tissue paper." Izuku stiffens when he hears this and tries to make himself as small as possible, which is a big mistake as the others notice this and give him a deadpan stare.

'So, it was you!' The three of them thought in unison as Izuku's face burned red.

"After rethinking everything, I know that it was beyond just a quirk." All Might decides to save Izuku from his predicament and continues to explain. "And not to mention, how young Mirio gains a new power out of nowhere."

"You know Mirio-senpai!?" Eijirou asks in shock as All Might nods sadly.

"I meet him in an unfortunate situation. My old friend did something terrible to him, and I witnessed everything." All Might says in a somber tone.

"Sir Nighteye..." Izuku growls in anger, surprising All Might. "To think I used to admire him and even sold my All Might merchandise to that bastard."

"I beg your pardon!?" All Might expect a lot of things, but nothing could prepare him for such a random statement.

"S-sorry, it was nothing..." Izuku mutters in embarrassment.

"... Anyway, I did finally accept the fact. Not long after that, Naomasa declares that he quits his detective job and accepts Gang Orca's job offer." All Might says with a grin. "It was thanks to him that I was slowly able to understand the world of Dungeons and Magic."

"I swear, why do whenever people say that I fear being charged with blatant plagiarism?" Eijirou mutters as Izuku shrugs.

"Naomasa talks about you all so many times. I thought I was listening to an uncle tired of dealing with their niece's shenanigans. I pity him, but now we have something in common." All Might lets out a chuckle as the Trinity sweatdrops. "Anyways, which part of the Might Tower are you three want to visit?"

"The backyard," Izuku answers immediately, earning a nod from All Might as they walk to the backyard. To All Might's surprise, he saw a giant gate completely chained up, and he felt heat radiate from behind the gate.

"I swear, that wasn't there this morning..." All Might comments as Izuku pulls out a key from his inventory before he approaches the gate. "Young man, be careful! We don't know-!"

In an instant, Izuku grabs the lock and inserts the key into the lock. As he unlocks it, the lock falls to the ground, and the chains slither away like snakes. Everyone there could feel the heat getting more and more intense as the giant gate opened, revealing a bright red portal behind it.

"Well, then, guys. Shall we?" Izuku asks as he summons [Balmung] while grinning. Ochako smirks before pulling out a golden key as it transforms into a gold staff while Eijirou grins before transforming into his therianthrope form.

All Might watch the scene with wide eyes. He has heard Naomasa telling him about the kids multiple times, but seeing it himself is surprising. All Might could sense the power radiating from each of them, with Izuku having the most power out of him.

Suddenly, several spirits pop out of Ochako's side, startling All Might, and he can sense her power increases drastically, almost as much as Izuku's. And why does his quirk seem so trigger-happy all of a sudden? It feels like a fanboy cheering over a scene.

(A/N: Could any of you guess? It's easy. :3)

"Alright, let's go!" Izuku says before the three of them charge towards the gate. Before All Might could say something, he saw them enter the portal as the gate closed behind them.

"...hope they're alright..."

Demon Realm

"Whoa..."

Izuku looks around the dungeon in horrified awe. Everything around him seems to be in ruins: buildings torn apart, cracks on the street everywhere, and hellfire burns everything. After a closer look, Izuku felt his gut twisting.

The entire town seems to be a perfect replica of Roppingi, a ruined one, but a replica nonetheless.

"Whoever designs this dungeon has a sick sense of humor..." Izuku mutters.

"This...looks like Might Tower's backyard..." Ochako checks the surroundings in horror.

"Don't worry too much, my lady," Leo says in a reassuring tone. "This is just a replica. None of this is real."

"I know, Leo. But, it's scary that they could replicate it in such accuracy..." Ochako mutters anxiously.

"Indeed, the details were too much even for a replica..." Virgo mutters as she floats around the surroundings.

"And where's the damn monster we're supposed to take down?" Taurus exclaims before he gets slapped by both Leo and Virgo.

"Don't jinx it!!" They yell in unison.

"Guys, please," Ochako calls them out while sweatdropping. "It's not the time to fight with each other." Ochako looks at Eijirou. "Eijirou, do you smell or hear anything?"

"Only smokes and fires crackling," Eijirou growls in annoyance as Ochako looks at Izuku, who summons Shadow Tengus to scout through the sky while holding Kuro.

"Alright, now for some land scouts..." Izuku says before he deploys Archers and Assassins to help. Igris remains by his side, standing idly. "While we wait for their reports, let's prepare for possible attacks." Izuku pulled potions out of his inventory and gave them to Ochako and Eijirou.

"Potions?" Ochako asks.

"Fire Resistance Potions. It will help with dealing with Hellfire." Izuku says.

"You don't drink one?" Eijirou asks.

"Bro, [Hellfire] is one of my active skills. Do you think I could be affected by it?" Izuku asks while raising his eyebrow.

"I thought it works like MOBA games where even a fire element expert could be affected by enemies' flames," Eijirou mutters as both of them drink their potions.

"Nope. It grants me Hellfire Immunity." Izuku says with a grin, causing Eijirou to slam his glass bottle while yelling 'motherfucker!'. Ochako stares at Leo with a dead expression.

"Why learning [Flames of Courage] didn't grant me immunity to hellfire?" Ochako asks as Leo looks away, sweating profusely.

"W-well... [Flames of Courage] is more of Celestial magic than Elemental magic, and the power of Celestial Realm could be affected by the power of Hell, so...yeah..." Leo stutters, lowering his head in shame.

"...that's sucks," Ochako mutters in annoyance, causing Leo to feel a metaphorical arrow piercing his heart and fainted. Izuku saw one of the Tengu fly backs and squawk at him, causing him to be baffled at its odd behavior.

"They found something, my lord," Igris explains as Izuku looks at Tengu before nodding.

"Alright, we wait for a moment, then you lead the way," Izuku says as the Tengu nods. He waits for a moment before the shadows all return with dejected feelings as the Tengu gives them a smirk. Izuku watches as they all glare at one Tengu who finds something, acting all smug.

They all walk together and watch the Tengu lead them towards something. As they get closer, each of them turns slightly pale. It's a giant dog with three heads, each having a pair of horns; two of its heads have flames on their heads, and they all wear metal headpieces. Izuku believes it to be Cerberus from the legends and he assumes it's about 5 meters tall.

"W-why does the Tengu lead us here?" Ochako asks shakily. Izuku looks at the Tengu who points at the back of the Cerberus, noticing that there's a door behind it.

"So, to progress, we need to beat that mutt, huh?" Izuku mutters as the Tengu nods. "Well, since flames won't affect him, given there's some on their heads, I shall take another approach." Izuku puts [Balmung] into his inventory before summoning a pair of knights. He absorbs them as it turns into a pair of blades.

The Cerberus notices their presence and lets out a growl from their snout. Their red eyes glared at the three of them, and each head glared at one of them.

"This is gonna be an insane fight," Eijirou mutters as he hardens his claws with his quirk and wind.

"Yeah," Izuku says with a grin as his eyes glow green for a bit, signaling that [Appraisal] has been activated.

[Cerberus, The Gatekeeper of Hell]

[The guardian of the gate that leads to Hell, it takes their job seriously. Hardened through countless battles and consuming souls attempting to break through the gate for their selfish desires. The beast is feared by every demon in existence if not for his dedication to his job.]

[Powers: Rage - Allow users to double their stats for 3 minutes. Hellfire - commands over the flame of hell. Iron Defense - High durability. Fangs of Blade - Able to pierce through thick defenses with their fangs. Debuff Immunity - Immune to all debuffs. Earth Magic]

[Weakness: Water, Ice, Celestial Magics]

"That thing's weak towards water, ice, and celestial magic!" Izuku says as they both nod. Izuku summons Mages, who shoot streams of water, but Cerberus merely stomps the ground and covers himself with a thick earth wall. Izuku rushed towards the Cerberus as he used [Undine's Blessing] on both of his side. He strikes his shadow blades right on the dog's guts and grits his teeth when it did nothing, before he hits an incoming flames with water, turning it into steams.

"[Flame of Courage]!" Ochako shouts before she shoots a condensed fireball, hitting one of the dog's heads and causing it to roar in pain. Izuku takes his chance to summon more water to hit Cerberus, but to his surprise, the flames automatically move around the Cerberus and protect it.

'Some sort of defense mechanism? That wasn't on the Appraisal!' Izuku thought before he got hit by Cerberus' Hellfire. To the dog's surprise, it did nothing to him.

"[Claws of the Beast King!]" Eijirou uses the distraction to land a powerful wind claw, piercing through the monster's thick hide but he was burnt by the Hellfire.

"Eiji!" Izuku shouts in concern but sighs in relief when all it does is burn off Eijirou's clothes. "Alright, let-."

Before he could finish his words, the Cerberus rushed towards Izuku and slammed his paws at him, sending him flying. Izuku summons Tengu to catch him, and to his surprise, the dog's attention is on him as it continues to rush at him.

"[Colossal Strength!]" The Cerberus was slammed by a powerful blow by Ochako, holding her Celestial Staff with mana glowing at the top of the staff, shaped like a hammer. The Cerberus recovers quickly before it disappears in a blur, and flames start to shoot towards Izuku, Ochako, and Eijirou.

Izuku immediately uses [Undine's Blessing] to protect him and his allies from the onslaught of hellfire. It relentlessly rains on them before the Cerberus appears beside Eijirou and tries to bite him. Thankfully, Eijirou uses his strength to hold its maw off.

Izuku takes this chance and extends the shadow under him and the Cerberus. His eyes glow dark green as his hand clenches. Several Shadow Chains appear beneath the Cerberus and wrap around it, immobilizing him. The Hellfire immediately went off, trying to burn it down, but Izuku's insane MP allowed it to constantly regenerate.

Eijirou, after noticing those flames are from the heads that are covered in flames, takes his chance to let go and moves away before covering his hardened claws with his quirk and wind and cuts one of the head covers in flame, decapitating it instantly.

Ochako also takes her chance using [Flame of Courage] right at the one head with flames on top of it, destroying it instantly as the Hellfire stops defending the dog. Izuku uses [Undine's Blessing] to create a waterblade, causing the last head to let out a whimper before Izuku decapitates it in one slice.

[You have defeated Cerberus, Gatekeeper of Hell]

The three let out a sigh of relief as they watched the corpse remain unmoving. Izuku confirming it also added more relief to their worries that the dog might've revived in some way.

"I will never look a dog in the same way ever again..." Eijirou groans out.

"Eiji-bro, you hate every dog ever since you got your powers," Izuku says in a deadpan manner as Ochako lets out a giggle.

To be continued
