High School Hack and Slash

Sonic Boom

「Nnggigigi… It, it won’t open.」

Shaking and pressing her hands against the door, Mikan-senpai, who is unable to make it flinch even as she tries to push it open with everything she’s got, is so cute.

Should I land her a hand, or should I watch over her.

Emotional-wise, I’d like to watch over her forever.

Perhaps noticing my lukewarm gaze, Mikan-senpai puffs out her cheeks like a mochi and gives me a glares.

「You see, during the period when the magic circle inside is activating, it will trigger the lock. It’s not that my strength is insufficient or anything, alright, do you understand?」

「I totally understand.」

I want to pat her so badly, but the president guard force is flashing at me from the stairwell landing, so I have to endure it.

「Geez, for better or worse, workshop is a designated hazardous facility, you know? If you’re not careful, you’ll get bit by a ghost, after all.」

Here it comes, ghost.

I wonder if it has three hairs on its head.

「Rather than a ghost, it’s an amorphous monster… something akin to an apparition or specter, I suppose. Sometimes they just pop up with a whoosh, it’s true, I’m not lying.」

「… Hahaha, I see.」

「Looks like you don’t believe it, huh. I don’t care if you get so frightened and unable to even stand up, alright?」

The alert level rises at once.

Not good, I wonder if I’ll be able to protect Mikan-senpai.

In the past, when I was holed up in the mountains, I encountered specter-like phantoms a number of times.

Many of them were skin and bones only specter, dressed in tattered armor like that of sengoku warlords.

The ones that rushed at you while raising eerie bird-like cries as though they have gone crazy, wielding rusty, broken swords and spears.

From what I could see, they were lifeless, so I thought they were of specter kinds, but when I got slashed and stabbed, it plainly hurt.

「Ah, so specters are a physical phenomenon, huh」, as such a thought crossed my mind, I also fought them back physically.

How young I must have been, or so I reflect on it.

If I were to encounter a specter now, I would opt to run away, but at the time, I thought that maybe I could eat it.

Rather than the warlord, I aimed for the similarly skinny horsemen, but when I defeated them, they vanished.

It was one vain battle.

Well, they were opponents that could even be defeated by my child self, but there were some strong ones in the mix from time to time, so I couldn’t let my guard down.

The type who had a halo on it was pretty tough, and then inedible.

I position myself behind Mikan-senpai who once again goes nngigigi, pushing the door.

There is a possibility that a slashing attack will come flying the moment the door opens.

I should prepare for a counterattack and be ready to cover for Mikan-senpai.

And then, at the same time as a clicking sound of a door getting unlocked echoes, the door opens, I grab Mikan-senpai, who moans huaa as she seems about to fall over, by her collar and pull her close to me, and unleash a Seiken-Zuki toward the specter that is crying kehihi with a wretched expression.

This specter one gets its nose crushed and blown away, but the feedback is pretty light.

I thought that the sensation of hitting a specter was more like hitting a heavy, low-resilience material, but I guess it’s the effect of leveling up or doing class change.

I thrust out my hands to repel the specter two and specter three, which stiffen while still having a shallow smile plastered on their faces.

My dim vision is changing in color.

Rather, it looks like the switch of my acceleration state ends up getting reflexively switched.

It’s a skill of 『Raijin』, which I’ve changed class to, that more or less enables me to move extremely fast by consuming GP.

It is also a very non fuel-efficient skill that drains my GP upon accelerating for about five seconds of bodily sensation.

In the monochrome world where time seems to have stopped, it’s hard to move as if the air sticks to you.

I think Saki’s 『Flash Attack (Scud)』 has better usability.

There was also a time when I tried to stealthily peek at Shizuka’s skirt from below in accelerated state, only to end up creating a sonic boom-like phenomenon, and getting terribly scolded afterwards.

It’s super useless.

I was thinking of sealing it since I didn’t know the way to adjust it, but well, sure enough, the trust gives rise to a sonic boom as it blows away the equipment along with the specters like an explosion.

「S, somehow, it went kaboom. And then bang!」

Mikan-senpai, who has come clinging to me from the front like a cuddly doll out of the pulling momentum, is getting flustered.

Since Mikan-senpai can perceive the series of events, it seems that she has also been dragged into the accelerated state.

In the workshop, a large number of unusually stout specters have appeared.

It seems that specters have a habit of congregating.

If left alone, things may get dangerous, so I ought to invite Mikan-senpai into the monochrome world with me too.

「It will be a little sticky, but please hold your breath and close your eyes.」

「Funya?」

As I hold Mikan-senpai in my left arm, colors vanish from my vision all at once.

◇ ◇ ◇

「Wha, what in the world happened, what in the world!」

「Let’s see, I also have no idea.」

In the middle of the workshop where the partitioning screens are blown away, the shelves are overturned and the equipment are scattered about, I try to play dumb.

It’s the pattern where I’ll definitely be scolded if I tell everything honestly.

I think that maybe, if I were to throw a dozen hand grenades or something, it would bring about such a messed up state.

Mikan-senpai, who is perplexed and flailing about in fluster, is super sweet.

Incidentally, her uniform is torn and ripped, revealing her orange polka-dot panties, so lovely.

The same goes for mine, with the sleeves blown off, my torn uniform is brimming with the end of the century vibe.

From what I can tell, it was torn due to the shock wave that surpassed the speed of sound and the resistance of the viscous air, but for there to be no damage to the body, I wonder what kind of principle did it work under?

Well, skill itself is an irrational phenomenon in a lot of ways, but I think it should still conform to the laws of physics.

「A, a gas explosion? That’s not it, perhaps someone accidentally blew up a magic or a card.」

「I see, let’s go with that then.」

Talk about a highly dangerous facility.

Rather than due to the effect of sonic boom that I perhaps accidentally brought forth for a bit, someone must have fumbled their magic and ended up triggering a gas explosion at the same time, no doubt about it.

There are a large number of white-eyed, blown off half-naked boys lying on the floor, but they must have been caught in the gas explosion and magic fumble.

This is a personal soliloquy, but it’s not that the thought that 「perhaps they were not specter」 didn’t cross my mind by the time I sent five or six of them flying, but the fox-faced dude who was sticking out his tongue was so disgusting, so I crushed them all the last one.

I felt that various things would burst out with a splat if I hit them with all my might, so I more or less held myself back there.

Also, I had a feeling that my points would go down if I hit the few girls who were in the mix, so I think I did a good job in avoiding them.

It would have a huge help if they could put up an icon like the 『HELP!』 icon from the old gun shooting game or something, though.

「… Wha, what, happened?」

「Ringo-chan!」

The ally character, who was surrounded by the specter-like enemy characters, remains cowering with their hands on their hands.

Or rather, it is Vice-prez-san of Adept Workers.

For the skirt around her ass to get rolled over and her panties to get slipped down, it could be said that the shockwave has done an ingenious job.

The girls who have lost consciousness or are lying on the floor also seem to be Adept Workers Senpais.

「Are you alright? Ringo-chan, and everyone else too.」

「… Yes, I think we’re alright, perhaps. Back at you, Mikan-chan, what’s with that appearance of yours?」

Vice-prez Rinko, shaking her head and checking her surroundings as well as her companions, is concerned about Mikan-senpai, who has received mysterious damage to her uniform.
