Nope! Ass kicking time!

Moka, Kurumu and Tsukanne turn around to watch the entire female swim club transform into mermaids, rushing on the other guys who joined and began biting them. The boys they caught began aging rapidly. "Don't think too badly of us! Luring men into the water and Sucking their life energy is just are natural way of life." Ichinose said, bounding through the water towards them before leaping for Tsukane. "ISN'T IT WONDERFUL!?"

Tsukane almost got bit by Ichinose before Kurumi transformed into her wings and pulled him to the side out of the way.

"You can't stop us! We're invincible in the water!" She cried, having missed her first lunge but turned around for the less experienced swimmer - Moka.

"No!" Tsukane shouted. Kurumu didn't need any other advise as she threw Tsukane at Ichinose, diving fist first into her cheek as he splashed down, helping Moka out.

"Don't think you can escape us, Tsukane!" Ichinose recover and begins swarming towards him and Moka, before a surge of energy rushes out, halting the advance. When they were able to look again, Moka's hair had turned gray, her eyes a blood red... and had her chest and ass become a bit bigger? "A-a Vampire!?"

Inner Moka glared at the head mermaid. "How dare you treat me like this!" She said, radiating an intense aura that intimidated the other mermaids.

"C-come on, what is this? I had my sights set on Tsukune! And I'm never going to give him up to someone like you!" With a snap of her fingers, Ichinose rallied the rest of the mermaids. "I don't know how strong you are, but in our territory, a mermaid will always be victorious! If you're going to beg for your life, now's the time!"

"Hmph," Inner Moka grinned with a dominating air. "Coming from a low class fish that can't think of anything but food? Don't make me laugh!" A pair of mermaids try to ambush her from behind, but she Simply leaps into the air, Tsukane punching up into the two of them as he'd been forgotten about in the confusion.

"You're too slow! You may talk tough, but it seems that's all you are!" Ichinose shouts at Moka. "You're a great target in the air! Die!" A swath of mermaids leap from the water at the vampire, the swimming club captain at the head. Kurumu goes in for a swipe, but only gets one of them before Moka knocks the lead mermaid flying.

"To take the bait and be caught so easily... you have to be a fish! Know your place!" She finishes the other mermaids with a barrage as they descend back towards the pool, Ichinose hitting the outer fence and leaving a dent in it as she collapses.

Tsukane leaves the pool and walks over to Ichinose, glaring at the prone, barely conscious mermaid. "After the first meeting, I'm just don't think swimming club is for us the way it is." He says, his confident mode having been going since the fight started. "Now, what to do with you?"
