The dungeon boss

The sixth floor

We see the four boys walking down the dark hallway heading for the sixth floor as bell is determined to make it while issei and Jaune and tatsumi are very hesitant about continuing upward

Jaune: Bell listen I get you wanna get to the top but shouldn't we head back 

Bell: No

Issei: Come on man it's better if we bring more people with us or something

Bell: and lead them to their deaths no

Issei: dude-

Tatsumi: issei he's right

Issei: Huh

Tatsumi: were some of the strongest adventures there is if we bring in some lower tier heroes or adventures what do you think will happen

Issei: I get what your saying but this dungeons been kicking our ass ever since we got here plus I died Jaune died and you and bell almost died on the fifth floor the only reason we're still alive is because that guy saved us

Bell: if you want to go back then you can go

Issei:.........*sigh* damnit fine I'll stick around

Jaune: Great....is it me or this hallway longer than most

Bell: Now that you mentioned it yeah it I-

Before bell could finish his sentence the floor beneath them opened up as they fall down into some dirty water as the boys rise up out of the water

Issei: What The hell happened

Tatsumi: the floor just opened up on us

Jaune: come on let's keep going

The boys start to swim to the next floor swimming through the dirty murky water with caution making sure nothing pops out of nowhere to attack them

After swimming for a few minutes they make it to the sixth floor where they see a swampy area

Bell: Ok so a swamp

Issei: i'm calling it right now it's probably a giant crocodile or maybe an alligator

Tatsumi: Maybe

Then the entrance and exit gets blocked off by the iron spikes wall as the battle symbols appear

Bell: Well get ready because here we go

The group prepare for a fight as they look around on all sides of the swampy area making sure no sneak attacks happen but nothing happened

Issei: Nothings happened yet

Jaune: Hmm strange

Tatsumi: You think it's a small monster or something

Bell: I hope not that'd be annoying but stay on guard guys we don't know what we're up agai-

Before bell could finish his sentence someone burst from out of the water uppercutting bell sending him up into the air as the figure then grabbed bell by the leg and looked over at the other three shocked boys
