The entire team watched you tear apart all of the dragons as you stabbed the Eastern Dragons until you ripped out their hearts, and then unleashed a- 

(Y/N): ELEMENTAL DRAGON KING DORUARUA KAMEHAMEHAAAAAAA! 

Then one of the Wurms breathed poison on you, but then- 

(Y/N): POISON DRAGON ROAR! 

You killed it with a poison that melted its scales off! 

Thistle: What's going on?! How are you doing this?! 

You then appeared in front of Thistle! 

Thistle: AGH! 

(Y/N): I bet you've never heard of Dragon Slayers before. Well, we can easily take down dragons like if they're made out of clay! 

Thistle: GET HIM! GET HIM GET HIM GET HIM GET HIM!!! KILL HIM!! FUCKING KILL HIM! 

The Wyverns pinned you down, but it was a Shadow Clone! 

Thistle: HUH?! 

(Y/N): ICE DRAGON TALON! 

You kicked the Wyverns in the necks and then prepared a massive magic spell on Thistle, which pinned him down. 

(Y/N): Hey, Winged Lion! I think you should come out! 

You knocked the grimoire out of his grasp, and then it opened up. 

Then the other book opened and out came the Winged Lion in his former glory! 

Thistle: NO! This can't be! 

Winged Lion: Ah, your desires, Thistle, it's so wonderful! 

Thistle: AGH! 

He tried to take out the lion, but t bit his arm. 

Thistle: I'LL BL- Huh? What was it that I wanted to do? 

Winged Lion: That's so delectable. Desires left to mature for a thousand years really are special. This is prime stuff, Thistle! 

Thistle: Wh-What are you talking about? 

Winged Lion: Did you forget? I've been waiting for the chance to eat your desires for so long. I also ate your desire to resist. You don't want to struggle now, right? You see desires are my favorite dish. The world where I live in had none. No wonder you got sick of being limited. All that time and effort to make it, and it's eaten up in mere moments. On top of that, the satisfaction doesn't last long. What futility. That may be what makes it an act like o other though. I hate to admit it, but I've been thoroughly charmed by your meals. 

Then he reached into Thistle and pulled out a stone! 

Thistle: NO! NOT THAT! 

Winged Lion: How beautiful. It's your desire, formed of layer upon layer of various wishes. I almost hate to eat it. So I'll savor it quickly. 

He started to lick away at it. 

Thistle: NO! I'M GOING TO DISAPPEAR! I DON'T WANT TO! I- 

But then everything started to go dark, the faces of everyone in his mind faded over and over. 

Thistle: Someone ... do something ... stop it.. 

And then the beast ate it up. 

Winged Lion: Curses, it was too good! And here I was wondering what he would do in the end. But this is it? Oh well, thank- 

Suddenly you grabbed him. 

Winged Lion: Oh ... (Y/N) ... I did not notice that you were- 

(Y/N): So, desires are what you long for huh? Okay, Kitty ... how about this? 

Your Sharingan activated on him, and then- 

Everyone was back to normal size... 

Ruby: Hey! We're back to normal! 

Laios: (Y/N) did it! 

Blake: But where's Th- WHOA! 

Blake saw Thistle's body on the ground, lifeless. 

Blake: (Y/N), did you- 

(Y/N): Nope. Our new pet did. 

The Winged Lion appeared and nuzzled your side with his mane. 

Ruby: The Winged Lion? 

(Y/N): We should really get moving now. 

Weiss: Why? 

(Y/N): Because the Lord of the Dungeon is dead now, that means that- 

Winged Lion: The Dungeon cannot sustain itself. 

Everyone: WHAT?! 

(Y/N): Yeah ... the thing is ... without someone to govern the Dungeon ... well ... I don't think it's going to hold up anymore. Okay, Kitty, take us out of here. 

Marcille: But what about- 

(Y/N): Hang on. 

You quickly went to grab Falin's body. 

(Y/N): Now let's leave this place for good!
