You step out onto the surface of the water, and achieve perfect footing. With flawless precision, you walk across the surface of the pool. Your first and immediate target: Tamao Ichinose.
Tamao realizes that you're gunning for her, and flings Tsukune at you, before retreating into the water. Before you can react, he vanishes in a gust of wind.
"Put those bitches in their place, Jojo-senpai!" Kurumu's voice. You briefly cast your gaze around, and see her several meters above, with bat-like wings and a tail that ends with a devil's spade. Some kind of devil monster, perhaps something like a succubus? Regardless, she appears to have Tsukune's safety well in hand.
A member of the Swimming Club lunges at you from beneath the water.
ORA ORA!
You punch her, right in the face, with your hamon-powered fist. You can feel her skull start to give, and hear a sickening crack. You follow up with a hammerblow to the stomach, using your other fist. The sound of breaking bones is a sickening one for most people. ...but for you? That's just a signal that the party's gotten started.
The mermaid goes flying into the air until she lands on the fence, back-first. As if by conditioned response, all the other Swimming Club members come at you in a swarm.
ORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAAA!!!!
They all meet a similar fate to the first one. Some of them, you deal a kick or knee strike, but most of them just get your fists.
Once the carnage subsides, the pool is quiet. You stand coolly atop the water's surface, gazing into its depths. Tamao Ichinose hasn't come back up yet. A brief series of glances around the area confirm that you haven't gotten to her yet.
Several seconds pass. Suddenly, you spot movement to your right! You turn, and punch her so hard that her head explo- 「water?!」
A shrill voice behind you screams, "AN OPENING!" ...it's Tamao! Could she have「manipulated the water into a duplicate」?!
Before Tamao can strike your back, you can see a sudden flash of light. Ignoring it, you sense an immediate window to attack, and make use of it. You spin in place on the water's surface, and drive your fist into Tamao's stomach from below.
The entirety of the pool before you is now frozen solid, as is a considerable fraction of Tamao's body, except for her head. It's surely the work of a youkai, but something tells you it isn't an enemy.
You ignore that as irrelevant, as Tamao weakly asks, "W-why? We... we didn't do anything to you..."
...how ignorant can a high-school student be? Does she really not understand that there are people who fight for someone other than themselves, for their friends? Does she not comprehend that if you hurt a person, that person's friends will seek revenge? Is this girl so... lonely and isolated, that she doesn't know how to trust in others?
Yeeaaahh, NO.
Your eyes narrow, and you offer her a simple and concise answer.
"「You pissed me off.」"
ORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAORAAA!!!
You batter Tamao's body with a hurricane of punches. Before you're done, it feels like you've broken every bone in her body.
ORAAAAAAAA!!!!
With one last knockout punch, you send Tamao flying through the fence, and into the peanut gallery, where she ends up destroying several benches that were bolted in place.
Three minutes ago, Tamao Ichinose was a woman with a beautiful body, who used it to her advantage to prey on those weaker than her.
Now, her outside looks just as messed up as her inside.
