By the time Izuku finished explaining, Severus was fit to eat glass. Lunging to his feet, he cursed colourfully and then figured to hell with it. With Albus calling his name, he stormed from his quarters and took off back toward where he had last seen Alastor Moody. The brute must have been out of his blasted mind! Unforgivable spells used on children and not just any children, his grandchildren! He may have only been aware of his grandparent status for a few days, but Merlin be damned, the bond took quick.

Students scattered at the sight of him. Most knew to leave the man be, but even Slytherins dodged when they saw the thunderous look on the face of their head of house. Eyes wide as they scurried off to their last class of the day. Even the Slytherins knew not to mess with him. Durmstrang and Beauxbatons students also moved out of the way. Curiously watching the Potions Master storm by.

Catching sight of Moody entering the great hall, Severus picked up his steps. He didn't care there was about to be an audience. Teachers and students milled about, mostly their guests taking advantage of the space to work on assignments from their Headmaster and Headmistress, rather than sit in on random classes as they had been doing, but the instant Severus stepped in, all chatter died, and every gaze was locked on the furious Wizard.

As if sensing him, Moody turned, grunting as he situated himself, leaning heavily on his cane. "That grandson of yours go whining to you? Don't get your knickers in a twist Snape. I was just—Ooof!"

Honestly, Severus wasn't even sure what possessed him. Using his wand would have at least been lest crude. But the minute the fool spoke, he saw red. There were gasps and startled yelps from the teachers and students, but Severus only had eyes for Moody.

Nose bloodied; Moody set his furious gaze on the Potion's master. "Are you out of your mind?!"

"Severus! What in the name of Merlin has gotten into you?!"

Barely glancing at Minerva, Severus itched to pull his wand, but resisted as he flexed his aching fingers. "Tell me Alastor…have you taken leave of your senses? Because honestly, that's the only blasted thing I could think of when my Grandson told me you used an unforgivable on him and his classmates!"

"What?!" Minerva spluttered; her outrage instantly redirected. "Alastor! Please tell me Severus is attempting a joke!"

Alastor scoffed, pulling out a hanky to dab at his nose. "Getting your undies in a proper twist. It was good practice. They needed to understand how the Imperius curse felt!"

"You injured a student!" Severus snarled. "Right now, he is getting cracked ribs mended. Something you should have done yourself the minute the boy hurt himself!"

"What is the fuss?" Karkaroff scoffed, stood with his students and rolling his eyes at Severus. "How else do you expect students to learn how to defend such spells? We begin teaching ours from first year!"

"Not in Hogwarts," Minerva snapped. "Not only is it illegal, but it is highly dangerous magic. Sweet Morgana! Alastor, explaining it in theory is one thing, but you used it on students? Who was injured, Severus?"

"Mr Potter," Severus answered. "I examined him myself. Not only was he hurt pretty badly, but this wretched fool expected him to go under the spell again, until my grandson stepped in."

"A disrespectful brat that boy!"

Severus barked out a rare laugh. "Disrespectful? For what, Alastor? Stopping you from causing a minor further bloody injury?! Do you even hear yourself?"

"Oh, he does…He just doesn't care."

Everyone's attention snapped toward the new voice. Aizawa stalked forward, dark eyes narrowed in temper and Severus noticed, his son had donned his capture weapon. Albus and Hizashi were right behind him and neither looked happy.

"What on Earth is going on 'ere?" Madam Maxime demanded. "A squib daring to talk to a Wizard in such a manner? How dare 'e!"

"Mind your tone Madam Maxime," Severus snarled. "That is my child you dare to insult."

"No need to fret Okaasan," Aizawa said breezily, a dangerous smile on his face. "I can handle myself against a mouthy Meiji. What's going on here, is a teacher using not only harmful magic, but illegal magic on children…one of my children…and I will damn well have something to say about it. Hell, I'll put him on his ass for it."

Alastor spluttered, barking a humourless laugh. "With not a whit of magic to access? How do you intend to do that, lad?"

"That is enough!" Albus snapped, blue eyes lit with a rare fury, as he stepped up next to Aizawa and Severus. "Alastor, if you could, I would like a word in my office."

Nose still leaking, Alastor grumbled and reluctantly followed, Minerva right behind them. By sheer willpower, Aizawa resisted the urge to knock him flat. Hell, he was tempted to give in just to prove he could.

Muttering in French, Madam Maxime went back to her students, ushering them from the hall. Karkaroff doing the same as he tossed out comments angrily in Bulgarian. Facing his mother now that it was just them and his husband, Aizawa chuckled. "I'm guessing that busted nose was you?"

Severus flushed, straightening his robes with an embarrassed huff. "It sort of…happened. I had intended to hex him to hell and back, but it just didn't seem to be enough…What does Okaasan mean?"

Aizawa blinked at the sudden topic change, pale cheeks turning crimson. Out of the corner of his eye he noticed his husband grinning. Bastard! He hadn't intended to say it, didn't even know he wanted to say it. But it had always been something he craved, so, it sort of popped out. Whether Severus would accept it, was another thing. "Uh…it means…well…it's Japanese for…mother."

Eyes widening in surprise, something warmed inside in Severus, a little smile tilting his lips. After thirty years, he figured he'd never hear that title…felt he didn't deserve it. But he wasn't about to refuse it. "Oh. Well, I like it. Okaasan it is."

That easy acceptance filled a part of Aizawa's heart in a way nothing ever had. "Okaasan it is."

-SING-ME-HOME-

Harry winced, watching Madam Pomphrey prod at his ribs, before pulling her wand to run a scan. Her face twisted in irritation. "Merlin! Alastor you foolish bastard! Mr Potter you've three cracked ribs and some bad bruising. Thankfully I can fix you up in an instant."

"Good to know," Harry breathed. "This hurts more than breaking my arm in second year."

"Ribs tend to be a bit more painful, since you have to breathe and it aggravates it," Madam Pomphrey explained gently. "You'll feel fine in just a tick…"

Harry waited patiently as she cast the spells. Relief flooded him within moments, his breaths eased, and he watched in fascination as the horrendous bruising faded from black and dark purple to pale yellow. "That's much better."

"I can't heal the bruising completely, so you will be tender for a day or two." Madam Pomphrey said cheerfully. "I'll give you a salve for the rest of it. As for Alastor, should I fire call the Headmaster?"

"No need, Madam Pomphrey," Hermione said, helping Harry sit up. "We've already informed him."

"Good. Mad as a bag of cats that man, but even this is crazy for him."

Ron shook his head. "Absolutely barmy. The spell felt awful. We all reacted immediately. Accept Harry. Took him almost ten minutes to do whatever it is Moody wanted and even then he fought."

"That's nothing!" Harry said excitedly, fixing his shirt and grinning. "Did you see Izuku? The spell couldn't even hold him!"

"To be fair, it's extremely weak magic."

Head snapping toward the doors, Harry flushed at the sight of Izuku leaning against the door. His usual sunny smile on his face. "How do you call magic like that, weak?!"

Chuckling, Izuku made his way toward Harry's bed. "My brother Hitoshi. You saw his Quirk, brain washing? Let's just say, that spell has nothing on it. Thanks to extensive training I can shake Hitoshi's Quirk. So, the Imperius curse wasn't all that hard."

"Seriously?" Ron spluttered. "Mate! That is amazing. I can't imagine fighting off something stronger!"

"I thought we wouldn't see you till dinner, Izuku," Hermione commented. Fussing over Harry, which the boy shooed away good naturedly.

"Yeaaaah, that was before my grandmother stormed out ready to murder Professor Moody."

"What?!"

"Oh, Merlin," Madam Pomphrey moaned. "I wonder who I should prep for. My money is on either one."

"It's so weird watching Snape be so Paternal," Ron said, shaking his head. "He was outright…nice…to you Harry."

Izuku laughed. "I've heard how cranky he can be…is he really that bad?"

"Yes." Hermione, Harry, Ron and Madam Pomphrey responded together, making Izuku laugh harder.

"Glad to see someone's having fun."

Hearing the familiar dry tone, Izuku looked over to where Severus had stepped in, followed by Aizawa and Hizashi. "By the bloody knuckles, I'm guessing diplomacy didn't win?"

Severus snorted. "Who said diplomacy was ever on the table? Madam Pomphrey, I'm sure you'll be having Alastor shortly…broken nose."

"Oh, Merlin…Severus!" Madam Pomphrey bemoaned. "He's a retired Auror…He could cause you trouble!"

"In what capacity?" Aizawa demanded from behind his mother, eyes rolling. "I'm guessing he's about to be in a whole lot more trouble. Speaking of, how is Harry?"

"Better now that I've healed his cracked ribs." Madam Pomphrey said with disgust. "I'll say it again…mad as a bag of cats that man!"

The teenagers chuckled amongst themselves. Leaving the adults to it, the four headed out. They all wanted to drop their belongings at Gryffindor tower before heading to dinner.

"Thank you," Harry said, walking up ahead with Izuku as they made their way through the halls.

Izuku blinked. "For what?"

"For getting me help." Harry sighed, looking ahead to his friends. "Hermione is too stuck on the rules and Ron tends not to question anything once it's been supposedly passed by the Headmaster. But you did."

Izuku shrugged. "Just because they're teachers, doesn't mean they're always right. Encouraging something harmful after you've already been injured is idiotic. Hell! Encouraging magic that is illegal is downright villain behaviour."

Harry wasn't used to people defending him like that. Oh, his two best friends had his back, but when it came to Hogwarts staff? Yeah, they tended to give the teachers the benefit of the doubt way too often. Unless it was Ron and involved Slytherins.

"I think we want to trust our teachers. Even with this stupid tournament, where I don't even meet the age parameters."

Coming up short, Izuku groaned, smacking his forehead. He was such an idiot! Darting by the confused trio, he promised he'd see them all at dinner and rushed toward the library. He had read every book in regard to the Triwizard tournament but had misunderstood one detail. If he was right, he just needed to double check a tiny binding spell.

-SING-ME-HOME-

Yawning, Hitoshi made his way through the halls. The odd gaze from students followed him. Curious, mostly. They had thankfully gotten over whatever misguided terror had engulfed them, thanks to their Transfiguration Professor not knowing how to manage a situation with some decorum.

Technically, he wasn't supposed to wander on his own, but Katsuki had already broken that rule and since the only chaperone available was babysitting Eri and couldn't really leave their quarters anyway, he figured he'd risk it.

The library was pointless. As much as magic intrigued him, he wasn't interested in reading up on a topic he couldn't use.

A breeze catching his attention, Hitoshi noticed a window was open. The sun had already nearly set, but a walk sounded nice. Jumping out, he landed with a soft grunt and looked about. Catching sight of a lake, he started off toward it. It was certainly colder than he was used to. Probably should have grabbed a jacket on his way out, but that's what happened when you did things on the fly.

In the distance he could hear the owls from the owlery and sounds he didn't recognise from the forbidden forest. Severus had given them the lecture on approaching it and after Izuku had gotten on the wrong end of a Chimera, he wasn't about to go against him.

At the lake's edge, he crouched and reached out to run his digits over the calm water.

"That is probably not a good idea."

Jumping at the thick Bulgarian accent, Hitoshi lurched upright, purple eyes landing on a boy wading through the lake. He was broadly built. Thick muscle visible beneath sallow skin, with eyes so dark they looked black and dark military cropped hair. Frowning, he backed up a little.

"You're saying that, while in the water?"

"I'm not vorried about vat is in here coming after me," the boy responded with a grin. "I am Viktor…Viktor Krum. You are one of the brothers of the green haired boy, yes?"

"Hitoshi Aizawa," the younger teen introduced. "You're one of the students from the other schools."

Nodding, Viktor moved toward the bank and stepped out of the water. He wore a pair of swimming shorts and at his full height he was easily six foot three. It wasn't often Hitoshi felt small around anyone. "Vat brings you out here? Is dinner not soon? I know you sometimes eat in the hall."

Hitoshi blinked in surprise. "Eh, yeah…Whenever meals in our quarters get dull…I suppose it's hard to miss our habits when we stand out."

Viktor grinned. "Well, yours. I noticed you. A beautiful man like you is hard to miss."

Startled, Hitoshi's cheeks blazed red. He wasn't used to romantic attention and certainly not from such a stunning male. "Oh…I…" Yeah, he had nothing articulate to respond with.

"You are a shy one."

A polite way of saying he was a blubbering mess. Messing with a curl of his purple hair, Hitoshi shrugged. "I'm not a talkative type."

"I am not usually either," Viktor admitted.

"Any particular reason you're out here?" Hitoshi asked curiously. "I know this school has some nice baths and I'd think November is a little cold for swimming in a lake."

"True," Viktor commented, pulling out his wand from a thigh holster and casting a drying spell. "Unfortunately, these Hogwarts girls seem intent to follow me about. It has gotten irritating. I doubt telling them outright I'm gay vould make much of a difference."

Hitoshi winced. "I noticed when I was out doing some of my morning training. Whole groups trailing behind you the last couple of mornings. I can see where that would get annoying."

"Immensely." Viktor sighed and catching sight of one of his classmates, he waved in greeting. Reaching out and taking Hitoshi's hand he pressed a kiss against his knuckles. "Till ve speak again, Hitoshi."

Heart stuttering, Hitoshi watched the older boy start back toward the castle. Hoping they would speak again, Hitoshi continued on his walk, a smile on his face.

-SING-ME-HOME-

Massive dishes of food appeared through the tables, chatter filled the great hall as everyone began to fill their plates and ghosts moved between the tables, calling out greetings as they passed. Harry craned his neck, frowning. Aizawa, Hizashi, Katsuki, Hitoshi and Eri sat at the extra table added on to the top table eating and chatting away to each other, but there was no sign of Izuku. None of the trio had seen him since he took off.

"Where do you think he is?" Hermione asked, noticing where Harry's gaze was locked.

"Library?" Ron suggested. "That was such a Hermione Granger moment. Where he figured out something and had to confirm it first before telling anyone."

"It is better knowing you are a hundred percent correct, rather than making a fool of yourself!" Hermione hissed in embarrassment; cheeks flushed pink.

"I never said otherwise!" Ron defended, completely oblivious as to how he offended her.

Chuckling at their antics, Harry glanced around again. Every now and again he copped a flash of the ridiculous Potter Stink's badges. Rolling his eyes at the obnoxious giggles of students older than him, only to jump when Aizawa suddenly crouched down beside him.

"Blimey!" Harry croaked, just about swallowing his startled yelp. "Warn a bloke, Shota!"

"Sorry, kid," Aizawa chuckled. "Just wanted to see if any of you saw Izuku. Katsuki is about ready to ransack the school."

Wincing, Harry glanced by him and sure enough, Katsuki was arguing lowly with Hitoshi, while it looked like Hizashi was trying to calm him down. "We haven't seen him since he came to find us in the infirmary. He said something about him being an idiot, that he needed to check something and then he ran off."

Frowning, Aizawa righted himself. That would have been nearly two hours ago…so where—

Everyone jumped when the main doors were thrown open and Izuku rushed in, cheeks flushed and eyes bright. Aizawa called out to him, but his problem child had his sights set on only one thing and that was the Goblet of Fire sat at the top of the hall, fire flickering lowly, as it would continue to do until the tournament ended.

Confused gazes followed, voices calling out, only to grow more frantic when the teenager pressed a hand to the goblet, whispering. "Peto intrare…"

Screams filled the hall when blue flames suddenly erupted from the Goblet and surrounded Izuku. Those closet scrambled away from the blaze, whereas Aizawa, Hizashi, Katsuki and Hitoshi ran straight for it, but couldn't get near it. The heat was too much! Out of desperation, Aizawa activated his Quirk, but unlike usual magic, it didn't shut it off. There was nothing he could do! His kid was trapped!

Dazed, Izuku wasn't sure what happened. The fire had surrounded him in a burst. Momentarily blinded, he waited to be burnt to death, instead a warm chuckle filled his ears. Eyes opening slowly, he blinked in surprise. All around was white and grey. White grass, mountains in white and shades of grey and slap in the middle was a large throne, a woman made entirely of blue flame sat upon it.

"What brings you to my domain, young one?"

Her voice was warm, rich, inviting. Taking a step forward, Izuku wasn't even sure where to begin. "You're aware of everything going on I'm guessing?"

The fiery being smiled, her blue hair flickering as she chuckled. "Oh, very much so. It is always amusing to watch. Especially when these creatures insist on keeping me trapped, I need something to keep me entertained."

"Trapped?" Izuku asked surprised. "You're a prisoner?"

"Indeed, I am…." Smiling, she stood fluidly, her flaming gown sizzling as she walked. "My name is Calida, and I am a fire spirit, who was unfortunate enough to end up bound by a Wizard back in the thirteenth century. All the power I possess, and all he wanted me for was to power an accursed Goblet to play an equally accursed game."

"Can anyone free you?"

Calida blinked; the fire spirit genuinely surprised. Her expression went soft. "Oh, young one…unfortunately no. The binding involved requires a very tricky spell and the blood of the Wizard's family line, which has changed so much I wouldn't know where to start."

Izuku deflated a little. "Oh."

"Oh, fret not, young one," Calida promised gently. "But thank you. Now! Why not tell me why you are here."

He didn't want to leave it. He wanted to help her, but Harry was priority. "This tournament…the rules and parameters are stated by the Wizards hosting it and woven through the contract with binding spells…ones…I guess…you power."

Calida nodded. "Honestly…They could do it without me…but my power can't be broken. But it can be bent…so young one, what is it you need?"

"My friend…Harry Potter," Izuku explained. "He was bound just like the others the minute his name left the Goblet."

"Something of which still burns me," Calida scoffed, flames blazing white for a moment as her temper spiked. "Something else forced me to call his name. I'm still trying to figure out what…but yes…he is now bound like the others."

"What if he doesn't meet the chosen parameters?"

Calida frowned. "Such as?"

"Harry doesn't meet the age requirements." Izuku said hurriedly. "There was a seventeen and over age restriction placed in the contract binding spells, but Harry is only fourteen! So, I need to know about the Guardian clause."

"The Guardian clause?" Calida repeated. "Young one, the clause has never been activated, simply because the Guardian must be a volunteer and they must assist without using their magic. No Wizard or Witch has ever been willing to do such a thing."

"I am!" Izuku stated firmly. "I volunteer to stand as Harry's Guardian in this tournament."

She saw it. The truth in his heart. There was no fear and raw pride filled her. "Oh, you are just a wonder! Fine. It is my right to allow it and I shall. On one condition…do not speak of my existence, young one…I'd sooner not have others dwell on my shackled life. But I am grateful for this time. It was nice to speak to someone again."

"I wish there was more I could do."

Calida grinned. "Oh, the chaos you are about to cause will do me just fine. Farewell."

In a sudden rush of blue flame, Izuku was tossed back. Everything swirled until his mind couldn't take it and the dark took him.
