'My God!　Trainer Orsen, all the demons I've raised so far have been fed to the King Slime!''

You're a cold-hearted son of a b*tc*!
You are a demon trainer!

　Orsen is cursed at.
　But he shouts back with a distorted smile.

''Hmph, hahahahaha!　Don't worry about it!　Because they will live on in this child's... 'meh' forever!

　This emperor metal slime, Metacchi, shows mysterious movements, such as stretching and shrinking its body, and changing its shape irregularly.
　It seemed to be able to transform quite freely.

Come on, go!　I'm going to show your power to a mythical demon!

　At that signal, the huge mass begins to move slowly.
　As expected, it is large and lacks agility.

'But this is where it gets interesting!　Even just a metal slime species, against which no magic or physical attacks can work!　That's the size of it!　It was thought to be an impregnable mythical grade demon, but how will it really fight against this new species of slime?''

　It's true that Befi's physical attacks don't seem to be a good match, and it's useless for Libby to sink them with water.
　Will Fenny's fire work?
　You might be able to vaporize it if you try hard enough, but what is the boiling point of metal slime?

　Well, let's go with the plan.
　I had no intention of bringing out these three bodies from the beginning.

''I can't wait to see how much more power I'll gain if I eat a mythical grade demon...............''

　Puh-leeze!

...What?

　Orsen let out a deranged voice.
　He must have thought that a mythical grade demon would appear.
　But what actually stood in front of the Emperor Metal Slime was a small kindred spirit that was only thirty centimeters in diameter at most.

''Slime?''

　Of course it's a pullle.
　It's a bit grotesque when it's big because it's a mixture of black and purple in color, but right now it's cute because it's as big as the aforementioned.

''There's some kind of creepy slime out there...''
What is that color?

　What are you talking about?
　It would be adorable, no matter how you look at it.

'What the hell is this all about?　Trainer Arrell, I'm just bringing out the slime for a head count!　This is the price you're willing to pay to find out how strong your opponent is.　But this size difference!　This is going to be over in an instant!'

　Apparently, Pullle wasn't counted as a force to be reckoned with.

''To bring out such a small slime.......are you trying to taunt us....... Fine!　b*tc*, feed that thing to him!

　Metacci is closing in on Pullle.
　However, instead of running away, Pulluru charged at him.

'What a brave slime!　And if you think about it, the only person who has ever done anything to change the rules is Arrell!　You don't mean to tell me that they're going to exceed expectations here as well?

　--Petty.

　Such a sound was heard as it struck the surface of Metacchi.
　And then it is swallowed up by the body of Pruru Metacacchi.

''Ehh........ ......Gohonhon!　It's still what we expected!　Trainer Arrell, what the hell do you think you're doing by leaving those demons to die?

　The audience booed.

''Don't let the demons die in vain!
Stop playing around!
Bring out the mythical class!

　I don't mean to play around, though.

　With Pullle inside his body, Metachi resumes his progress as if nothing had happened.

Here it comes.
Are we gonna be next?
No, that won't be necessary.

　Apparently, Befi and the others also think that Pullle has been killed.
　But that is the slime of the demon world.
　There's no way it would die like this.
　On the contrary.

'What?　What's going on, Mehta?

　Suddenly, Memachi stopped moving.

'The enemy is much further away, you know?　What's going on?

　Metachi didn't respond to the trainer's voice and began to shake her huge body with a shudder.
　It looks a bit painful.

Metachi?　What the hell happened?　--What?　This, this is.........?

　I peeled my eyes away when I noticed that Orsen was there.

　A part of Metachi's body.
　The place that had just swallowed Pullle earlier had turned black.
　It's as if the silvery metal had gone rotten.

　Moreover, that black area was getting bigger and bigger, as if the poison was spreading.
　At the same time, Metacchi's suffering was becoming more and more intense.

''d*mn........Metachi, hurry up and spit it out!

　When Orsen hurriedly ordered that, Metachi dexterously separated only the black part of it and drove it out of the body.
　Now it was back to its original beautiful silver color--and then I thought

Wha...?

　Tacchi writhes in agony again.
　When I look at her, I see that a part of her body has turned black again.
　And it is expanding.
　Apparently it was not completely removed.

　In addition, the black lump that should have been separated began to move on its own, and then it jumped at Metacchi.
　And then, it enters Metacchi's body.

　Before I knew it, the blackness had spread to the entirety of Metacchi's body.
　And it's getting darker and darker...

Good job, Pullle.

　Puh-leeze!

　A giant slime that shook its body happily at my words of exertion.
　That's right, it looks like Pulluru has been absorbed, but in fact, it has taken over Metacchi from the inside.
