Hizashi Yamada vs. the demon horde

Chapter four: The end or is it?

One week after Nezuko and the boys were all turned back into humans, Tanjiro and Zenitsu walked into the teacher's lounge room at UA High School, both letting out exhausted breaths. Looking around the room, the two boys saw Nezuko sitting on the sofa sandwiched between Aizawa and Sekijiro watching TV, Hound Dog and Cementoss talking to Toshinori while sitting at a table off to the side, and Hizashi was playing Poker with Inosuke, Muzan, Luci, and Dark Shadow.

"Well we just killed the last of the loose demons," Tanjiro said as he and Zenitsu announced their presence when entering the room, "I swear, that Kiyo Terauchi gave us more trouble than Gyomei, Obanai, and Mitsuri combined."

"Hizashi gives me more trouble than any three other people that I know combined," Aizawa called out from where he sat on the sofa watching TV.

"Oh come on, Sho," Hizashi replied, "I'm sure that I can't be that bad."

Aizawa turned his head to look right at Hizashi. "...At this point, it wouldn't surprise me if you somehow became friends with All For One."

Looking at his hand, Muzan said, "With all due respect, All For One is kind of weaksauce."

"You're just annoyed he was aiming to take your title from you, dude," Luci replied as he laid his hand down with a smirk, "Three straight."

"Royal Flush, bitches!" Inosuke said as he laid his hand down, "Beat that!"

The others playing Poker all folded, given that Inosuke had the best possible hand that can't be beaten, only tied with by other Royal Flushes. "Damn it," Dark Shadow said as Inosuke scooped up his winnings, "That was the last of the loose change in the small crock jar that Fumi had kept on his desk in his dorm room."

"Well now that we've just finished dealing with the last of the demons that we ought to be worried about," Zenitsu asked, "What else left is there to do?"

"Nezu says that he wants to try to fill up the first year hero course classes to make up for how most were killed slash turned into zombies slash killed again," Sekijiro spoke up, "Hey, you boys think that you'd be interested in becoming pro heroes?"

"Will we get to enjoy the five B's if we do?" Inosuke replied.

"Well not on campus," Hizashi replied, "But off campus I don't see why not."

Tanjiro gave Inosuke a curious look. "...The five B's, Inosuke?"

Listing off of his fingers, the boar masked Demon Slayer said, "Booze, blunts, and BIG BOOTY BITCHES!"

Luci, as he gathered up all of the cards to shuffle them, remarked, "I had you pegged as something of a party animal from the moment I first saw you, Inosuke. Glad to see I'm still as perceptive as I've always been."

"You know, I think that I might give taking Fumi's place in the hero course a shot," Dark Shadow said, "I mean, I know me even better than Fumi did. I bet I can master my powers in next to flat."

"And hey, at least we still got Kirishima and Tetsutetsu," Hizashi said, "I got a feeling that everything will go fine, just fine."

...

Meanwhile over in the Support course workshop, Hatsume and a number of other support students were working on something on a table; it seemed to be a robotic suit of some kind. "Bring the life support system frontal control panel," a third year boy said, his order being carried out by Hatsume.

After Hatsume got him the requested item, the third year boy placed it on the chest of the robotic suit, securely screwing it in after connecting some wires between the open hole in the chest and the small wires dangling out of the life support system frontal control panel. After that, the third year boy turned around to flip a switch, causing jolts of electricity to arc over the robotic suit.

It jerked up, like a person jerking back to life via defibrillator.

A second year boy looked to the third year boy. "Do we have a pulse yet, senpai?"

The third year boy looked at the readings on the screens above the robotic suit. He gave a wicked smile. "...Yes." The third year boy turned to Hatsume. "...This was originally your idea, Hatsume, and you were his most frequently referred student." The third year boy gesture to a remote that he was offering to the pink-haired girl. "You should have the honors."

Hatsume took the remote from the third year boy, pressed the one button on it as she said, "Power Loader-sensei. Arise." The table that the robotic suit was on lowered slightly before the one end started going up, allowing the robotic suit to be shown more and more as it was slowly raised to a standing position. It was dressed in all black, with a helmet made from the modified remains of All For One's first black helmet.

Eventually, the table stopped shifting, showing that the suit looked sort of like Power Loader not in his old mech suit, except nearly all black. The support course students all turned to look at the Power Loader robotic suit, with the third year boy saying, "Power Loader-sensei. Can you hear us?"

Slowly, the head of the Power Loader robotic suit turned to face the third year boy. It made some noises that sounded like breathing through a mechanical breathing support system of some kind. "...Yes, my students." The Power Loader robotic suit spoke with Power Loader's voice, but filtered through some sort of translation system.

"We collected your remains and brought them here so that we may revive you as a superior form of being," a chubby first year girl said, "We were able to save most of your organs. As a matter of fact, your brain was surprisingly in tact, which made reviving you loads easier than what I'd anticipated."

What was just revealed to be the revived Power Loader turned to face the chubby first year girl, who stood behind Hatsume. "...And my genitalia. Is it safe? Is it alright?"

Hatsume looked troubled, as if she had no idea how to break this news. "...I'm afriad... Power Loader-sensei... that your genitalia looked to have been devoured by what I'm guessing was a wild feral wolf. All that remains is roughly ten percent of the scrotum." Hatsume gently shook her head. "Your manhood couldn't be saved."

Power Loader looked to be trembling with a mix of despair and anger. He trembled so much that he broke free of the restraints binding him to the table. He stumbled forward a few steps before he gave a single skyward turn of his head. "NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!"

...

Back in the teachers' lounge, Hizashi nodded once again as he said, "Fine, just fine."

Folding his arms over his chest, Muzan said, "Yes, the only thing left out there that I'm aware of at the moment that's even remotely a bother is All For One, and even as I am now I could probably take him with little backup if any."

Toshinori gave the progenitor of demons a wry look. "I'd be against underestimating All For One if I were you, Muzan. He's far craftier and stronger than you give him credit for."

"Well considering the man's only way that he's a threat involves quirks," Dark Shadow said, "We could potentially take him down with an array of powerful persons who lack quirks. Granted, he'd most likely kill me so I shouldn't be on the team, but I bet Muzan, the Demon Slayer boys, and Luci could be the Suicide Squad needed to end All For One for good."

Arching a wry eyebrow, Aizawa said, "I actually want to learn more about this whole 'vampire convent' thing that All For One is supposedly worried about. I mean, given that we've dealt with zombies, and have just finished up a deal with demons, I think that All For One's supposed worries concerning vampires might warrant some investigation."

Turning to look at Aizawa, Toshonori said, "Aizawa, there's no need to worry. All For One is a crafty old bastard. He must of come up with the whole vampire thing because he wanted to throw out a red herring in order to lead us astray in order to carry out his unknown, true diabolical plan."

Hizashi turned to Luci. "What do you think, my dude?"

"That if there is a vampire convent," Luci began, "Then none of you had better come crying to me, because I don't deal in stuff like that at all."

...

Meanwhile, over at an undisclosed location, a small child was seen coming out of a house. They wore a baggy hoodie with the hood up, so it was impossible to tell who they were, or even what their gender was. The child, swaying ever so slightly as if not feeling well, wandered away from the house they had come out of. Unbeknownst to the child, they were being watched by a resident of the house as they wandered off, who looked on for a bit to make sure that the child was alright before retreating away from the window.

Walking through their house, the resident said in a woman's voice, "That young man was the latest of the children that I've shared my cursed gift with. Now they won't be lost forever, unlike what had happened to my child at UA." The mysterious woman passed by a mirror hanging on the wall. She removed her hood to look into the mirror, even though it didnt show any manner of reflection at all. The woman was a vampire, after all, and vampires couldn't see their reflections in mirrors, outside of niche circumstances like magic.

The woman continued to look on into the mirror, despite how that was pointless. "...There are so many children who need to be saved from being lost like my child was over at UA. I cannot let any of them be lost. I can save all of them. I will save all of them. Save all of them by sharing with them my cursed gift. ...Well now, Nezu. Your idiocy four and a half years ago turned out to be good for something after all." The woman then threw her head back before laughing evily, knowing full well that her plans will come to fruition.

...

Back in the UA teachers lounge, Toshinori said, "Are you sure, Luci?"

"The only undead I deal in are standard zombies," the devil began to explain, "But then again you should know that from what my good chum Hizashi had done in my name a short while ago."

Hizashi, with a bit of a knowing look, pointed out, "Well in my defense, I forgot what happened when I had last pulled a stunt like that over in Racoon City."

Dark Shadow folded his arms over his chest as he said, "So if Luci doesn't deal in vampires, then who does? Also, are we sure this vampire thing is actually going to be a thing?"

Looking to Dark Shadow, Hound Dog asked, "What do you mean?"

"Given the setting that we live in," Dark Shadow began, "Wouldn't it make more sense for us to have to deal with a bunch of robots going coo-coo bananas on us?"

"What's a robot?" Tanjiro asked in a curious and mildly confused tone, drawing likewise nods out of Zenitsu, Inosuke, Nezuko, and Muzan.

The others all looked to one another before all of them turned back to look at Muzan and the Demon Slayer crew. "...Oh yeah, you guys really need to get caught up on what things are like now," Hizashi began, "Given that you're from a time period centuries in the past. Gather around, kiddies, Uncle Hizashi has a story time to run." And so, Hizashi went into great detail about what robots were, as well as what all they can do for society when good.

He also covered what could happen if the robots went against their programming and do bad. Out of the folks from the time of the Demon Slayers, only Muzan and Inosuke didn't looked worried, but then again one is a one-thousand plus year old demon, and the other one is Inosuke who is thrilled by the concept of getting to fight stuff.

As for Aizawa, he'd like it if they could all get a break.

THE END

Author's notes;

Sorry, Aizawa, but the end isn't in sight here any time soon. Well this has been the second romp that saw Hizashi have to deal with a big mess. But there's still a few more to go, especially since some of them had spawned from Hizashi's past escapades. Keep your eyes peeled for future installments of the 'Hizashi Yamada vs.' series;
