Here's the next installment, written and ready on December 15th, for your viewing pleasure.
I swear I own nothing, not the place, time, any pictures I use outside of any I potentially commission, or the setting of this writing. What I DO own are means by which generous people can help and support a young man if they should choose. Available here and here, or my profile for those curious. The first is to my P A treon, and the second is to a fund, for commissions or if you think I could use a little something extra.
We be doing things now, Boys and Girls.

Chapter 17: First Preparation
OR
No Kill Quite like Undead Over Kill

The Cabbage Migration would be upon the Town of Axel in two days now, and Izuku was getting as much ready as he could.

When he first heard about the event, he had assumed a festival or something celebrating the vegetable would be coming to town. It would be stupid, but might have roots he didn't know of.

But no. It was crazier than anything he had ever heard of. The literal cabbages, along with stray lettuce apparently, would fly through the sky by the hundred to near thousand across the country for an ill-defined reason.

However, even that wasn't true. Over the course of his training, along with the ready working relationship he had established with the Guild through Luna, to say nothing of the sheer amount of money and capital he was generating with the wave of completed Quests and the mass selling of Health Potions by the crate. You could save a lot of money when you didn't really need to eat that often, the thought mostly just never occurring unless Izuku saw someone eating something and thinking 'Oh yeah, I should to.'

That wasn't the point however. The point was WHY the Cabbage traveled, and boy was it a doozie. The vegetables themselves didn't just move when they were ripe or ready to seek greener pastures with more nutrients. This was just what was passed around and the Guild backed up to ensure none looked deeper.

The truth of the matter was what harbored INSIDE the vegetables. Spirits. Thousands upon millions of Air and Earth Spirits, colliding and coalescing into every single inch of the plant, all with the intent of creating an easily disposable and movable container for them to use. The vegetables leaves merely provided it an acceptable facsimile of 'wings' while still protecting the root center where the bulk of power was stored.

Their destination? The gullet of a sleeping Earth Titan calling forth every spirit it could for a sacrifice large enough to reawaken it fully. This was the truth of the Cabbage Migration. A massive beast calling for food to literally fly into it's mouth, and the Guild had known about it for Centuries.

It wasn't all bad however. For all that the Migration had been happening for centuries, that actually worked to Humanities advantage. Towns had been built along their path both for the natural environmental advantages, and to serve as vanguards to figuratively and literally cull the herd. Adventurer's were paid top dollar for each Cabbage taken down, and while less for lettuce, still at least a bit of change. The fact that the same concentrated Experience they stored within themselves by the same people who took them down and devoured them first merely sweetened the deal, ensuring everyone would try their hand at catching the devious ingredient. Even in the worst case scenario, only around 40% of the total gathering had to be stopped, as the gathered amount would simply dissipate back into the environment unless delivered in a large enough burst, with the time it would take to make a new call being far past the cut-off call.

All this was explained to a shell-shocked Izuku, because he showed an interest beyond 'Why Cabbages?' and the fact that he opened up a school where such information could be important if anyone else cared enough to ask.

It was also the reason why said bone-boy was setting up as many contingencies as possible, wanting to take down as many as possible, even if Axel was just the first town of 12 for the Migration to hit.

Some were reasonable, and could be explained away, such as the Will O' Wisp torch lights along the halls and outside of the building, tied to a Crystal Ball in his 'office' that he kept going with a mana infusion every other day or so. Another was the installation of a Gate formed like rib bones that could swing open, double cross to form a cross pattern, and jump upward up to thirty three feet in return to becoming half as thick.

The more insane things was the skull shaped cannon on the top of the school that shot out a massive hand shaped hook to drain energy out of the surrounds and the carefully placed shoots of bones scatted every three to seven feet between one another all around the fields around Axel. The later two felt especially ridiculous because he forced his students to help with it, all of them doing so methodically with flat faces and eyes, except for Sheer's regular indifference to what he did when not chopping wood.
Okay. The cannon might e overboard, but better to have it and not need it. And more than that, this could be a great time for a lesson!

"Megumin!" Izuku called out to the nearest student still in the school, the rest out on Quests or avoiding being shanghaied into preparation planning.
The Witch in question startled back for a moment, nearly but not actually dropping the book he had given her a week and a half ago, which even just seeing brought a smile to his face.

Magic was influenced by how you felt about a spell, what you knew about a spell, where it comes from, and what kind of environment it would be going into. With Explosion, it could easily be said that the Girl knew every instance it had looked like, verbs used to describe it, and how to perform it. But she knew almost nothing of the others.

So Izuku wrote her a book based on how explosions physically worked, how they reacted or caused other stimulus to react, and different ways on how the same result could be achieved through multiple means, most of which gathered through the years of living and theorizing on just what and how Kacchan could be effective. While her goal was still solidly to create the Biggest and Strongest Explosion of all time, it would definitely be more accurate to say he was trying to have her make the most Effective Explosion, or a New Type of Explosion for any kind of situation. It was still his habit of thinking of Spells and Skills as Quirks, but the thinking seemed to be the same between them so far as he'd found. Nothing in this world was so simply two-dimensional if one looked at it.

But that was him just getting side tracked again, a habit that had been growing more he'd noticed since becoming a Lich. Still, Megumin had composed herself, book stored away and now stood posed in a half bow, cape fluttering in the breeze of her arms moving.

"Yes, Bastard-Sensei! What do you want your Star Pupil to do? Fetch you more bones of your enemies? Search the world over for legendary materials? Brand your wicked truths and tales into my fragile heart!?" She swooned, grabbing her chest and glaring with a half pout, even as Izuku sweat-dropped.

The only thing that hadn't changed was her exaggeration and frankly kind of chuuni way of speaking. To translate her words, she had asked if he needed more bone shards to string together or plant, if he needed her to go get some groceries or more health potions, or if it was time for another lesson. It...took some getting used too, with more than one freak-out at the beginning.

"N-no, none of those things Megumin. I just want you to gather the rest of the students for tonight. I...have a few last things to finish." Izuku finshed off a bit mysteriously. It wasn't his intent, but it had be a surprise!

And it seemed to do the trick better than intended, if the sparkly eye of Megumin said anything.

"Ooh! Of course! I shall bring my fellows in suffering as soon as they are able! Now, I shall away! Watch as I vanish like smoke around an impact crater!" Megumin called as she thrust to the ground a small black ball, creating a smoke screen and forcing Izuku to cover his eyes and cough for a minute.

"Cough! Cough! Ack, why did Chris give her those?" He choked after a minute of trying to breath, turning his head back upwards and seeing Megumin caught in the corner of the door, cape snagged on the doorknob while she froze in place like a statue as they both locked eyes. Calmly, and with a deft hand, she released her cape from her shoulders and continued to walk away, as if it had never happened. Izuku simply sighed as he went to to retrieve the cloak, before folding it neatly and putting it at the corner of his desk.

She'd be back for it later, and he DID have some work to do for now.

-TIME SKIP-

"You want us to what." Andrew spoke flatly.
"DEBUT!" Izuku beamed back at them all, succeeding only at putting a massive smile on Megumin's face, and a hesitant one on Chris. The rest were equally unamused.

"Okay. I thought that was what you said. What does that MEAN, though." Andrew asked again, palms together as if to cut away the stupid.

Izuku took a moment to think about that before nodding. It was a fair question.

"As of this conversation, all of us are relative unknowns in the Town, much less he general country, and certainly so for the world. We all have individual quirks and stories, yes, but that isn't much. "

"You murdered the local Toad population to such an extent that they won't be a problem the Axel area for the next 15 years. In a day. Before making a school from their BONES."

"Like I said, local stories. But this isn't just about me. This is about ALL of you. " Izuku waved off before getting serious, surprising the others who now leaned in cautiously.

"You all are at this school to learn how to be Hero's. This is what I promised and what I have been doing. But being a Hero isn't just about strength. It's about being there when others need help. It's about being a figure a person can look to, and think 'With them here, I can be safe'."

"This, a chance to make your name known. Not as Adventurer's who go on lots of Quests or based on hobby's. But as strong people who drove themselves farther than those around him to reach those dreams." Izuku said. He neither raised his voice, shouted out to the heavens, but you could hear a pin drop with how intently they listened the same, disinterest long gone.

Chris was the one to break the silence. Hands on her knees white and shaking, but she looked forward with a fire in the eyes that made Izuku prouder than he'd ever felt before.
"What...what do we need to do."
