It seems that the Demon King's Castle is located in the west.
　Based on such rough information, we headed westward to the west.

　On the way, we saved a number of towns, villages and cities from the Demon King's army.
　It seems that the further west you go, the worse the situation becomes.

　It seems that we really need to defeat the Demon King as soon as possible.
　It's said that heroes once defeated him, but I wonder if he's gone now?

Are you really trying to get to the Demon King?
Hmm?　Yes, but?
You might be alone, but you've got kids to take care of.
That's why. It just seems like good training.
Training...

　Your mother gives you a dumbfounded look.

　It's true that what your father says is messed up, but if we can defeat the Demon King, it's certainly better to do so.
　If left unchecked, the damage will continue to increase.

I'm looking forward to it!　Hey, Ark!
Uh-huh.

　It's usually Leila who's ready to do it.
　It doesn't matter what your mother and I say anymore.

　In the meantime, we stopped at a city.
　I'm not sure if I should call it a city or not.

　It's a good thing that the city is protected by a fine wall and has a reasonable amount of troops, as it seems to be the royal capital of the country that governs this area.

　Still, when we arrived, the city was on the verge of falling.
　The city gates were breached and the demons were allowed to enter, and they continued their desperate resistance.

　We watched the scene from the top of the city walls.

''Hey, Dad, are the soldiers fighting each other?''
'Hmm, looks like you're dead and turned into the undead.

　It was a horrible scene.
　I had been a friend of mine earlier, but now I had to fight my opponent as an enemy.
　Moreover, every time an ally dies, the enemy's strength increases.

The battlefield is spread out..... Let's split up. Are you two alright?''
Yeah!
Yes.
'Okay, then me and Laina will head out of the castle gates to that castle in the center. Ark, take the right and Leila, take the left to the castle.

　The fiercest battle is on the main street, which stretches straight from the breached gates.
　Nevertheless, the battlefield extends from there to the left and right.

　Leila and I jumped down from the ramparts, telling my mother, who seemed concerned about whether I was going to be okay on my own, that I would be fine.

　Leila and I parted ways, and I headed for the castle from the route on the right.

'O~a~'

　Immediately, the undead attacked us.
　By the looks of it, it was a civilian.
　He was probably killed by a demon and turned into an undead person after he failed to escape.

''Holy Ray.''
Ahhhh?

　Purifying magic works on the undead.
　The undead bathed in the light crumbled to the spot and became quiet.

　After that, the undead continued to approach one after another, and I sent the purifying light to them.

''What, what...?　The undead have stopped working...?
A child?　Hey, look out!
No, look closely!　That kid is using purification magic on the undead!

　The soldiers are surprised to see me.

''Gruaaaah!''
Oh, look out!

　A large bear demon with four arms jumped at me, probably thinking my presence of purifying the undead was a threat.
　Well, it's useless.

　Zang!

''~~~~~~~~~?''

　The slash I fired cuts the bear's body in half.

''Eh.........?''
What the hell just happened...?

　The soldiers are rolling their eyes.

　Yeah, I guess the undead around here have been taken care of for the most part.
　I decided to leave the rest to the soldiers and continue on.

''O~a~''
Uh-oh.
'Wow, that's a lot ... let's take them all down together. Holy Cross.

　The city is really full of undead.
　It seems that people who have been killed by demons have become undead without exception.

　There should be a necromancer in there.......but I can't feel any sign of him nearby.
　Is he controlling them from a distance?

'What is it.......I can feel a faint flow of magic.......?

　I concentrated and tried to sharpen my senses.
　Then I gradually understood the flow of magic power.

''It's coming from.......the castle.

　It was just the direction I was heading.

'The sooner we hit the source, the sooner we hit the source, right?

　Having decided that, I ignored the undead and sprinted to the castle.

　The closer I got to it, the more clearly I could see it.
　The main culprit controlling all the undead in the city is inside the castle.

　Moreover, he is probably controlling this many undead by himself.
　Moreover, if he is remote, he must be a master of necromancy.

　Increasingly wary, I jumped over the wall and entered the castle.

　A fierce battle was raging in the courtyard.

''Ooohhhhhh!''

　While roaring a roar, the one that cleaves the soldiers is a monster that seems to be a fusion of various demons.
　I think it's a chimera or something.
　I wasn't sure if I should join them, but I walked past their side in "stealth".

　The undead are already wandering around the castle.
　A woman, who was probably originally a maid of honor working in the castle, attacked me while shaking her hair.

''Holy Ray.''

　While purifying the undead, I ran around the castle, but the maze made it difficult.
　But thanks to the maze, I had a hard time finding my way around.

　And finally, I arrived at it.

"...here...

　There was a solid door that had been destroyed.
　At the end of it was a staircase that led to the basement.

　I killed the signs and went down the stairs and found the basement.

　I finally found it.
　The threads of magical power stretching throughout the city are converging in one place--

So you're the necromancer who controls the undead.
