I was about to help Mee retrieve the part that proved that the zombie was defeated, when.

'Ugh ......!

It was Satsuki who raised her voice.
When I looked to see what was going on, I saw Satsuki holding her head in agony and kneeling on the ground.

Something was clinging to the kimono-clad girl, illuminated by the flames of the dark night.
It seemed to be a pale, translucent figure of a naked girl, different from Satsuki.

The figure was, to put it bluntly, a 'girl ghost'.

'Now ......! No way... ghost!

Cyril, who was near Satsuki, shouted and backstepped away from Satsuki's side.
He then reached for the mace on his hip - but realized his mistake and withdrew his hand.

'No, ghosts can't be defeated by physical attacks: ....... But with the miracles I can use, ......'

The priestess said, gritting her teeth in frustration.
She seemed to have no way to deal with the threat that had suddenly appeared.

As for me, I can't help but be surprised at what has suddenly happened.

But panicking wouldn't make things any better.
I tried to remain calm and searched for information about the ghost monster from the knowledge I had acquired during my time at the academy.

Undead monsters, ghosts.
A soul that has died with regrets or grudges and remains on earth without being purified.

Because they are incorporeal, they cannot be defeated by physical attacks, even with magic arrows (magic missiles), fireballs, and other magic that inflicts physical damage.

The same is true for magic arrows, fireballs, and other spells that inflict physical damage. Then, what about the priest's Turn Undead, which is a miracle that purifies the negative power of the physical undead, but does not seem to be effective against ghosts, which are mental bodies.

On the other hand, ghosts don't have much ability to interfere with us, but there is one ability that is extremely troublesome.

Possession.
It is the ability to possess a target and take over its body.

I was wondering where this ghost had suddenly appeared from, but as a spirit, a ghost has almost no limitations in terms of movement.
You can fly through the air and sneak up on them from above, or you can go through the ground and attack them from underneath.

I had also cast an alert spell when I left the city, but due to the nature of this spell, it's not surprising that in this case I was lost among the zombies and didn't notice.

Now that that's out of the way, what should we do about this situation?
I've already used the fireball spell four times, and I don't have much mana left.
So for now...

After considering various options in my brain, I decide to use a single spell.
I begin chanting the spell.

'Ugh ...... ohhhhh!

'Satsuki! Satsuki, pull yourself together!

Satsuki is in agony, and Mie is shaking her.
Cyril gazes regretfully at the two of them.

Eventually, Satsuki stops screaming.
The anguished voice that she had just made is now a lie, and she goes quiet.
The ghost that had been clinging to Satsuki disappeared as if it had been sucked in.

'Sa...... Satsuki......?

Satsuki, who had been suffering on all fours, stood up slowly.
And then...

The girl in the kimono said, '...... hahahahahahaha!

The kimono-clad girl spreads her arms toward the night sky and begins to laugh like a mad woman.

'Wow! This body is amazing! I can kill those guys with this power! I can kill them all! I can kill them all! Wait for me, you trash, I'll go kill them right now...'

'Sleep'...

'Nyan...'

The girl who had been laughing loudly fell down.
It's not for nothing that it worked in one shot.

'Mee, give me the rope. I'll tie you up.'

'Ah ...... yes sir.'

The puzzled Mee took out a rope from her luggage and tied Satsuki up in a circle.
She also took into account the increased muscle strength from Satsuki's aura and tied her up tightly with triple ropes so that she could never escape.

That's it.
It was a difficult situation to deal with because it appeared so suddenly, but now the threat is over for the time being.
We will move on to the next step.
