The battle has begun.

　The water bullets deployed around the throne were simultaneously swept away by Dionis' signal.
　After communicating with Elfi by eye, I used "Acceleration" and "Reinforcement" simultaneously to evade.
　It's not just a matter of time before you get your hands on it.

Devil's Eye Ashburst!

　While lightly dodging water bullets with his superhuman physical abilities, Elfi fired a series of magic eyes.
　Small explosions attacked Dionis in succession.

''Like I said before, do you think you can kill me with this kind of child's playful attacks?
''--''

　The ash bombs explode in the direction of Elfi's gaze.
　Dionis was avoiding the attack that happens in almost no time, while snickering.
　After visually confirming where the gaze Elfi pointed at was, he ducked with plenty of time to spare.

　Yeah, I know you can do that much.

　That's why the destination that Dionis ducks.
　Towards that point, I had already unleashed my lightning magic.

"Just like this: ----

　He sniffed at the approaching lightning and Dionis dealt with it with a water bullet.
　At that moment, Elfi shoots his magic eye at Dionis, who has stopped moving.
　An explosion of greater power and scale than before occurs, but ----

...... I see. I knew it wasn't going to be easy.

　That explosion was slashed and obliterated.
　Dionis, who was clothed in water on the blade of the sword in his hand, was staring at me with his sword swinging down.

''Cliched attack, invisible coordination. Huh. Totally, you're letting me down. I thought you came here with a plan, but it's very disappointing.

　Dionis murmurs as he ruffles his hair with one hand.
　He lets out an exaggerated sigh and has a deliberately discouraged look on his face.

It's a good thing that you're not going to have to worry about the fact that you're not going to be able to get your hands on any of these things.
...... coming!

　Dionis jumped.
　He rushed towards me, sword at the ready.

'Hitting the weakest one first, isn't that the rule?
...... tch.

　He unleashes a spell of lightning with increased power.
　The purple lightning slides across the ground like a snake, trying to entangle itself in the oncoming Dionis, but

Things are different now, Amatsu.
......!

　Right before, a clear water covered his body.
　With just that, the purple electricity that hit Dionis's body dissipated.

''Pure water or ......!''

　Pure water that does not contain impurities is impervious to lightning.
　What they learned in science class in the original world, it was the same in this world as well.
　The water-attribute magic used by highly skilled sorcerers produced pure water, allowing them to play the lightning-attribute magic that they were supposed to be bad at.

''I don't know what you've been doing for thirty years, but I've been growing up. I'm not like you, who's just degraded with a skull and just degraded!
'......ggh!'

　I barely catch the water-clad sword flashes released by Dionis.
　It's a body that has been strengthened many times, but after receiving just one blow, it was made to retreat.

　Without the use of any magic, the demon tribe demonstrates several times the physical strength of a human.
　Dionis is the low-muscle strength of the demon race, but even so, I can't take it now.
　As expected, it's tricky.

"--Sen-Sen!

　Dionis' chase to me, who has lost his stance, is closing in on me.
　It's a good idea to be able to have a good idea of what to expect.
　I'm sure you'll be able to find a way to make it work.

'...... Come to think of it, you could also do a meatball fight, right?

　Dionis jumps back and avoids the fists.
　Without escaping, Elfi shoots his fists in succession.
　In the meantime, I also get my stance back up.

''Haaaaaah!
"--Jujuiken!

　The former Demon King's fist lightly shattered the ceiling.
　All of that, Dionis catches it all with his sword.
　Dionis tries to cleave Elfi's body with his sword, counter-like.

''--!''

　Then I interrupted him this time.
　I'm not going to be the only one who can do that.
　To Dionis, who had stopped moving, Elfi's demon king punch was slammed into him.

　It was only then that Dionis used one hand that wasn't holding the sword.
　Applying the juju sword to his body technique, Dionis catches Elfi's fist with one hand.

''Watch out!''

　Using the momentum of the receiving fist, Dionis jumps backwards.

''I won't let you get away!

　Without a moment's pause, Elfie tries to shoot his magic eye - but

Oops.

　As if to block it, a wall of water was created in front of him.
　A wall of murky water, not the clear, pure water that Dionis had produced until then.

''Elfiszak. In order for your magic eye to hit an opponent, you need to direct your gaze at the target. So if you block that line of sight, there's nothing you can do about it, right?

　Dionis's chuckle that can be heard from beyond the wall.

The extra wisdom goes around ......!
Elfie, thank God. But don't get too far ahead of yourself.
...... Yeah.
Take your time. So far, so good.

　Fine, that guy is underestimating me.

　From earlier, Dionis' gaze was mostly directed at Elfi.
　At the beginning, that guy understands that I'm weaker than Elfi.
　He's waiting for Elfi to show an opening while he lightly attacks me.

　Convenient.
　The more he is wary of Elfi, the easier it is for me to move.

　When the wall blocking the area in front of me disappeared, Dionis was standing a short distance away.
　With a sword in hand, he was still giving me a contemptuous look.

　Yeah, I'll admit it.
　To us right now, you're a rather troublesome enemy.
　However, this brings out its weaknesses.

　Carelessness, contempt, and arrogance in the face of the underclass.
　The guy has a habit of playing with someone he understands he can beat.
　It's a flaw of yours that Lucifina warned me about many times during my travels.
　Even after thirty years, fortunately, it doesn't seem to have been cured.

'As for Elfiszak, well, that's a fair point. But don't you think you're a bit weak, Amatsu?

　I'm not happy about you getting a passing grade," Elfi spits.

Well, I've been thinking about it ever since we were traveling," he said.　Well, the whole time I was traveling, I thought you were just a bunch of scum. A hero?　Heroic?　Save the world?　Save the world? You're human, aren't you? Even an incompetent bastard like Ryusus calls himself the most powerful sorcerer even though he's a human being, and humans really don't know their place.

　Dionis lifts his arm and chants.

　-- "torrent snake (Trent Deluge)"

　It was different from the previous water bullets.
　A huge mass of water was generated, and it took the form of a giant snake.

''--!
Iori, we're going back!

　Swirling, the giant snake comes towards us with great force.
　If you are taken in by that thing, you will definitely be drowned.

You know, I haven't heard that yet. Hey, who do you want revenge on?

　I ignore Dionis, who is smiling high, and run to get away from the giant snake.　
　Elfi leaps and kicks the wall and moves across the room.
　He avoids it lightly.

　But I can't make a move like that.
　The water is fast, and I won't be able to escape by just running.
　Will I use the hands I had prepared to get through the water bullets here?

"...... "Double Acceleration (Axel Double)

　I added "Acceleration" to the "Acceleration" that I had been using.
　I'm going to be able to use it to avoid the giant snake that's approaching me with even more doubled agility.

..........

　My whole body creaks and my body feels like it's going to pop.
　There is a sensation of buzzing and cutting muscle fibers.
　The "Strong Devil's Bracelet" has increased agility considerably more than normal, but the burden of that is also greater.
　That's a disadvantage of the bracelet.

''It's ...... but...''

　Every time I move it hurts, but soon after it feels like it's healing.
　It's all thanks to the continuous potions I took before I came in here.
　Thanks to the continuous recovery, I'm able to ease the burden of the double acceleration.

"Ha-ha!　You're taking it too far, Amatsu!　I can feel your desperation!

　He left the large snake behind and fleshed out to Dionis, who was standing just in front of the throne.
　I'm not going to be the only one who can do that.
　But

I've already seen past your sword.

　The blow delivered from the double acceleration was also received.
　This was with a sword held in one hand.

"Come to think of it, I was the one who taught you how to use a juju sword, wasn't I? Well, I thought there was no chance of that, but come on!
"Ggh!

　A re-burning of the first part of the game.
　He didn't lose his stance, but I get played backwards.
　Laughing, Dionis comes after me.

'...... Iori!
''Oops!''

　I'm sure you'll be able to find out more about this in the future.
　It's a combination of swordsmanship and magic.
　I'm sure you'll be able to find a way to make it work.

　...... Elfie, are you there yet?

"Ha-ha-ha!　See, Amatsu!　You're going to die if you don't keep up the good work!
"Ugh.

　I was just trying to resist the onslaught of Dionysus.
　Dionis was right, this guy taught me how to use a jujiken.
　That's how I know.
　This guy is highly skilled, but what he's using against us right now is a lickety-split, forceful attack.

　After nearly ten rounds of striking each other, it was just as I was beginning to run out of breath.

''Chi--I'll blow you away with my maximum firepower magic eye!

　In the distance, I could hear Elfi's numbing cry.
　Just like her words, I could feel her wearing high magic power.

''----''

　Dionis's attention is distracted by Elfi.
　He's trying to deploy a defensive magic with one hand to prevent the demon eye.

''--Haaaah!''

　I slash at this timing, but Dionis still managed to lightly defend against this one's blow.
　It doesn't stop there, it closes the gap and swings down a full-force blow.

I'm sure you can deal with it, even if it's just you, watching the rest of the world?

　With a mocking smile, Dionis raises his sword in time to match my timing.
　That's right.
　It's a good idea to be able to have a good time.

　--I've been waiting for this timing.

""Triple Acceleration (Accel Triple)--!"

　The sword in the middle of swinging down.
　That sword speed jumps up due to the "triple acceleration".
　It is precisely because he completely caught the timing of this one, Dionis was unable to deal with this flash.

"Ha!

　The blade slashed through Dionis's shoulder and side.
　Fresh blood spurted out and Dionis fell backwards.

''Gu......uh.''

　The triple acceleration has put a load on his body to the point where he is about to fall apart.
　Even a sustained potion can't cover the damage.

''...... ahhhh!''

　I suppressed the wound and aimed at the screaming Dionis and struck him with another flash.

''With a sword like that, yeah!''

　But this time it was dealt with.
　It's not just a matter of time before you get to the point where you can get your hands on it.

"Amaaaaatsu!　If you take it easy on him, you're going to get carried away!

　Dionis' onslaught while dripping blood.
　It's not the same as before, and the attack is played by a strike with a "technique" that is different from the previous ones.
　This is because the triple acceleration of the body speed is greater than ours.

　But that's only for now.

"Hey, Dionis. I'm not going to be able to get to know you better. Haven't you noticed?
Where's ......?

　The wound from the shoulder to the side.
　The flesh around the wound has become darker and darker.

What is ......?
''It's ...... swamp poison. You know it because you're a water demon general, right?

　That purple poison swamp that was there as soon as we entered.
　I took that poison and smeared it on the blade of my jade sword.
　Even a minor wound was enough to make the swamp poison effective.
　Whether it was the demon race or the demon race, this poison would work effectively.

''...... Do you think I don't have any solutions to deal with it!　I want you to detoxify this poison right now!
I won't let you!

　I'm going to add a double dose of reinforcement to my triple acceleration.
　I'm not going to be able to say that I'm not going to be able to do anything about it.

"Guh-uhh?

　A flash of lightning without regard to bone cracking.
　I'm not going to be able to get it right.

''Idiot. ......!''

　Dionis tries to detoxify himself, using the distance as a good thing.
　With the strain on his body, he can't close the gap quickly enough.

　But it's just as planned.

　Now I, too, have gotten far enough away (・・・・・・・・).

'--I told you?　Don't forget me.

　Elfie's crimson gaze, which had been using only his physical abilities to get past the giant snake, caught Dionis completely.

'Checkmate, Dionis.'
No way. ......

　Guffawing, Dionis turned his gaze to Elfi.
　Already, Elfi had accumulated magic power and was ready to go.

''Ya, stop----''

　That desperate scream was empty.

"Devil's Eye, Ash Bomb."


　A violent explosion engulfed Dionis.
