Go for Gwynevere.

Though you're slowed by your newfound backpack, you dart forwards as best you can, leaving behind Selinda and Kailani to take on the slippery jellymaid, and Snow to back you up with a bow and arrow which seems to work underwater. Thankfully you do have a technique to aid in such a situation. After swimming for a moment, you sink down to the foot of the second steps. The water around you warps as you ready to leap, and bringing Anyana with you, you're right in front of the Demon King in an instant using a mighty Bunny Hop! It catches her completely off guard, and you aim to disarm her with as fancy bladework as you can muster.

As a phantom elite class, it's easier said than done. Gwynevere is surprised, though she deftly parries the strike away and swims away backwards--feet upon the seat of the throne. "You are full of surprises, Demon King Warren. But in the ocean, I am undefeatable!" Even at her words, the water in the room shakes. She raises a hand once again, and you feel yourself lift up. The columns nearby almost seem to be sinking until you realize you're heading towards the ceiling. In her hand is a swirling vortex, and she speaks the words, "Power of the sea, come to me".

Snow, however, is ready. She lets loose another arrow just like she did before. It travels swiftly across the room, but is suddenly burned up by a blast of radiant energy.

She looks across the room to see Nelli with a hand out-stretched, even among her struggle with a dozen tentacles and an angry mermaid. The girl still managed to cast Celestial Blast, which hit perfectly enough to cause the arrow to not only go off-course, but burn into bits which drift off towards the wall.

You're caught off guard by an intense sucking sensation, and in no way a good one. You're pulled hard towards her hand, forcing the bobble out of your mouth, and after you're yanked intensely forwards, her palm clings to your stomach. From her other hand, a rapier is pointed towards your neck. Perhaps you'd be fast enough to knock it away, but you're uncertain. Perhaps she is as well as the two of you halt for a lengthy moment.

"... So you care about them at least," you mutter. "Getting me away from her before making a proper attack."

"I care about only one person here, and you stare into her beautiful eyes."

"Tell me what you're seeking, and I might even be able to help."

It's not going to be easy to fight someone who is not only an elite class, but seems to basically have an entire second class on top. She's like a rogue/warlock hybrid, with all these aquatic powers from her patron. Given we're underwater, she basically has control over the entire room. She really was trying to avoid hurting Anyana. I can feel it. Though that also means I might be in trouble now.

"I need no help."

"Well if we're gonna keep fighting, be careful where you're putting your hand down there. I might get excited."

Her eyes glance down but only for a second. You take full advantage of this fraction of a moment and thrust your hand to the side of her rapier. This allows you enough time to heave back and kick your foot towards her stomach, and at the same time, swing your blade upwards to knock the tip of her weapon much farther away. However, she responds to this by reversing her spell. Suddenly, the suction repels, and you're fired away with incredible **** directly into the nearest column.

You ignore the pain and kick off to gain speed, and swiftly swipe your own sword in her direction, which she deflects again, though is **** back as you strike out twice more. The two of you lock into a heated swordsman duel, though she does have the advantage. Clearly her patron's power allows her to move more easily underwater, even moreso than your magic necklace, and on top of that, her entire class is built around fancy swordplay, and that isn't even taking into account the fact that she controls the very substance you're swimming in. You need to act fast, but be careful.

That's when both of you have your attention stolen by a mischievous clown girl standing adjacent.

Gwynevere leaps both back and upwards to put some distance between both you and Candy, just in case this is some sort of trick. Unfortunately for her, it is a trick, and she's only made it worse for herself. You stare upwards at the floating woman--hair splayed behind her like a cloak of clouds. But her dress floats all the same. This would normally look quite intimidating, like a wavering ghostly shadow in the depths of the sea, though up her slender legs where there'd normally at least be a pair of black panties, which would blend into the colour of her dress, there's instead nothing there at all, and she doesn't even notice.

Candy stands with the underwear in her hands--pearls and all. "Wow. This was really easy to take. You were both so distracted."

The Demon King's eyes trail down towards what's in her hand. It takes a moment for the reality to sink in. Next, her eyes look down at herself, and suddenly her face floods red. She lets out a panicked gasp before thrusting down the front of her dress. "H-How dare you?!"

"Hehe. Want to know the second thing, Kyle?"

"I knew I recognized you. Candy, the obnoxious brat!" With a snarl, Gwynevere soars down like a striking falcon and stabs her blade right through the other girl's body. But she stares in confusion, and then rage as the illusory image disappears like running paint in the water. "Where--?!" She glances around, though her free hand is distracted now by holding down her dress. Her elegant and mighty composure as a queen of the depths is floundering.

Candy wraps the panties around your neck from behind and ties them by the pearl-covered string. "Right here."

"Gah!" The Demon King brings her hand up and throws her palm forwards, causing the water to thrust both you and Candy back, yet not even close to as hard as she's done so before. It feels more like a wave you may even have been able to hold your ground against if prepared, or able to hold onto anything.

You stand by Candy, ready for combat to continue. "And what's the second thing? Her panties come off easily?"

"No. That goes for everyone if you're good enough with your hands," replies Candy.

"Then what is it?"

"Every pact has a downside, and hers with Seno'nojoch did come with a trade-off."

Gwynevere takes a deep breath and attempts to calm herself down. After a moment, she floats ahead with her rapier ready, though keeps an idle hand downwards in case she needs to cover up. On one hand, the dress is long, though one the other, it's cut up the side even beyond her hip, meaning one of her legs is completely exposed. There's a hint of colour in her cheeks still, but she's regaining her composure.

"And what's her trade-off?" you ask.

"The more embarrassed she gets, so the more that arrogant persona fades, the weaker her powers become. This would hardly ever matter, and it's unlikely anyone would find out normally, so it's quite effective... unless someone does know. Then she's in trouble."

"I do know a thing or two about a girl trying to be clever with her weakness and failing miserably."
