Race: Draugr
　Class: The Immortal King (No Life King)
　Level: 108


　The information about the demon king's appearance is consistent with what we've heard from the adventurers beforehand.

　He is strong.
　His muscle strength and endurance are low, but his magic power is very high. Perhaps he's a good magician.

　Well, I'm still about two times higher in status than ...... but I'm stronger than Nell.

　You can't be too careful.

　And then--.



"...... crazy.

　The Immortal King, who still has a bit of skin left, is constantly emitting wailing, vindictive cries of woe, scratching his head with his almost bony fingers .

　There seems to be a strong resentment towards humans, and it looks at you with a gaze filled with rage and hatred - no, no.

　Its eyes are not (・・・・・・) turned toward us (・・・・・・).
　His anger is directed at something somewhere far away.

　This is exactly the kind of evil that befits a demon king: ...... What happened before he became a draugr?

　I've heard from the adventurers who fought against this demon king last time they attacked him that he's not like this.

...... Are you going to talk to that guy?

...... may not be possible.

　No matter how good its communication skills are, it would be impossible to have a conversation with it.
　This is a guy who completely shuts us down when we're out to take him down.

　...... Well, we've come this far.
　Let's give it a shot.

　I cleared my throat with a goblet and opened my mouth to face the enemy demon king with a conscious sneer.

"Hey, demon king. You look like you're having a lot of fun. I'd love to mix it up--Wow!



　The black fireball (・・・・), flying in without any preliminary movement at all.

　Since I had activated my magic eye, I could sense the signs of its activation from the flow of my magic, so I was able to avoid it in time to avoid it, but ...... that bastard attacked me without any real context.



"Don't unleash those freaky things!　I'm not human, a**h*le!

　In the face of countless black fireballs, I formed a large wall of water between us and the enemy demon king to defend against them - water, rotten (...).

'Hey, hey, hey, hey!

　I don't know what kind of magic it is, but the area hit by the black fireball instantly begins to discolor, opening a hole from which the rest of the fireball is coming toward me.

　You focus on evading it, running to the right and left to avoid it, but the enemy's high number of attacks causes it to graze my shirt with a single shot.

　My shirt, which has been torn, though only slightly, begins to discolor from that part of my shirt, just like the aforementioned water wall.

"Yeeeee!

　This is not good, so you immediately take off your shirt before the encroachment becomes too great, and then jump back in a big way from the spot to give yourself more room to avoid the attack.

Onii-san, are you okay?

　Unlike me, Nell, who was brilliantly evading all the bullets, comes over to you with a slightly impatient look.

　The erosion is ...... okay . Aside from ruining my shirt, you're going to be okay.

I'm okay!　But ...... that attack looks like it's better not to eat it.

I guess so, huh!

　You'll be able to see that, as you avoid the flying fireball.

　The black fireball apparently has a corrosive effect on things. I don't even want to think about what would happen if it hit a human body.

　--This magic is probably dark magic.

　It's a skill it possesses.
　There are many other skills such as 'skeleton summoning' and 'wraith summoning', but there is no skill other than dark magic that can unleash this black fireball.

"Nerd, what can dark magic do?

　The fireball, which will fly incessantly, will be broken in an instant, so I put up dozens of water walls to defend against it, and the Immortal King has activated his summoning skills or crush a large number of skeletons that began to boil in the throne room.
　It's Nell, handling the wraiths that began to arise as well.

　It's very reassuring to know that we are able to divide up the workload without having to say anything.

"It's a magic often used by 'rich' and the like. If you eat it, you'll suffer some kind of abnormal effects such as corrosion, confusion or blindness!　So, even a single bite is a big no-no!

　It's a state-dependent system and ...... is tricky.

　It's a very good idea to have a good idea of what you're looking for.

　The corrosion is especially annoying.
　Even if you try to defend against it with magic, there is no effective way to prevent it from eroding and destroying it so quickly.

　I'm sure you'll be able to find out more about it.

　...... This is no time to take it easy.

"Nell, we haven't shown you any new magic yet!　This is a great opportunity for me to show you!

　I didn't think about anything else and set a policy of just eliminating the opponent, and then I invoked - spirit magic.

'Leviathan'!

　A third of my magic power is eaten to create a dragon monster made up of many spirits.

　This throne room is quite large, but it still has its head on the ceiling, glaring at the enemy demon king.

　In terms of size, it's about the same size as the clay dragon from earlier.
　The amount of magic contained in it is on a different order of magnitude.



　It's a good thing that you're able to get the most out of the game.

It's not a good idea.

"Separation!　The Warding of the Precinct!

　I'm sure you'll be able to find out what I'm talking about, and I'm sure you'll be able to find out what I'm talking about, and I'm sure you'll be able to find out what I'm talking about, and I'm sure you'll be able to find out what I'm talking about.

　But this warding also begins to discolor as soon as it hits the dark magic, and although it holds up better than my water wall, within ten seconds a hole begins to open up ...... but that's enough.



"All out!　Do it!

　In the short time that Nell has earned it, the leviathan with all the magic of his body in his mouth - breath.

　Instantly, a roar roars in the throne room and an intense light that dyes your vision .

　The skeletons and wraiths that were caught up in it evaporate and disappear in an instant, and the aftermath hits us who were backing up a little bit as well, and a tremendous storm of wind pressure and sound slams down on our entire bodies.

"Whoa!

"What do you think, Nell, wow!　This is spirit magic!

"It's great, but there's more to it than that!　The Warding of the Precinct!

　I'm going to activate the warding spell again and build a wall in front of us. I can feel her love for you as well.

　As I dare to attack with all the magic I gave you, the Leviathan's entire body begins to disintegrate from the side where I released the breath.

　Eventually, the attack is finished and Leviathan can no longer maintain its existence and returns to being a mere spirit, when you can finally see properly, you look ahead with your vision.

"You're still alive: ...... That's great!

　The lower half of the body had completely disappeared, and the remaining upper half of the body was mostly burnt out, with several parts of the body erased.
　One more hit with a water ball would probably kill him.

　The Immortal King, who is on the verge of death by all accounts, is ...... but still carries a deep sense of hatred deep in his dark eye sockets.

　It's not against me for dying, but against something somewhere far away.

　That's how much his resentment continues to burn at its core.

...... Well, you're a dead man. You're dead, you're dead.

　--That's why I'll remember your vendetta for you at .......

　If I could manage, I'd work something out. If you can't, give it up.

　You're dead anyway, and there's nothing you can do about it now.
　Then let the dead die like dead people do, and die peacefully, without thinking about anything else. 　

　And then I...I brought down the roar.


　　　* * * *


...... What a not-so-flattering defeat. What the hell happened to you that made you do that ......

　It's not just a matter of time before you get to the point where you'll be able to get your hands on a new one.

It's a good thing that you're able to have a good time with them.

　I've been wondering about the difference between our Wraith girls and the Wraiths here: ...... Because the demon king had a strong grudge against humans, I think that the demons under his command may have shown their hatred to the fullest extent, as well.

　You'll be able to see that the will of your subordinate demon is understood by the demon king, and the will of the demon king is also understood by his subordinate demons.

Oh ...... I see. It's true that our wraiths are very naughty and Sy is very easy-going, so it makes sense that she is influenced by you. I'm sure that the demons in the dungeon are influenced by the demon king.

...... something, that being said, is a bit of a subtlety.

For one thing, I'm sure you're a mischievous and very fast-paced person, okay?

　...... Well, there's no denying it.

　I've decided that this is not a good time to talk about it, so I coughed deceptively and then continued.

Let's finish the job first. You can find the dungeon core at ......

　In one of the doors in the throne room, probably originally the captain's office, the dungeon core lay on the office desk.

　Unlike my dungeon core, it was not rainbow red, but dark red.

　Carotta had told me beforehand, "Bring back as much as you can, since it's a considerable reward for proving the defeat of the demon king," so I stretched out my right hand to the dungeon core - and with a (・・・・) pop (・・・・), it was absorbed into my palm (...) (・・・・) gone (・・・・・).

"Ah.

　Simultaneously, me and Nell.

"...... Onii-san?

"No, no, no, no Nell, I didn't mean to!　I don't know why, but it just sucked itself in!

　To confirm, I hurriedly opened the item box, but of course it was not there, and then I opened the menu: ...... Huh?

　In the menu, there is something in the "Dungeon" section.

　I immediately opened it and checked it out.

"Is this ...... perhaps this (...) dungeon (・・・・・・) became (・・・・・) mine (・・・・・) ......?

　If you look at the dungeon section, in addition to my dungeon controls, you can also use all of the functions of this ghost ship dungeon, such as "Add Hierarchy" and "Dungeon Area Expansion".

　...... Does this mean that because I killed the Demon King of this dungeon, I became the Demon King here instead?

Oh, my God, did you just rule this dungeon?

...... seems to be. It's not possible to retrieve the dungeon core anymore, but ...... what do you think I should do?

"...... can't help it, can they?

　Yeah. ...... Okay. I agree.

　I agree.
