Hachi Academy, inside Ryoubi and Ryouna's shinobi barrier
The twins are facing Ai, the fight hasn't started already.
"Ryouna, Ai is strong, so…"
Ryoubi starts, but Ai interrupts them with her most powerful attack.
"Ultimate Secret Ninja Art, Infamous Waterspout!"
Ai yells, twirling her whip like a spiral, which creates a giant water tornado.
Astonished by the direct use of her ultimate art, Ryouna and Ryoubi don't react quick enough to dodge and get stuck up into the waterspout.
However, the real danger isn't the water or the speed, but the creatures inside it…
Indeed, the water a filled with Portuguese man-of-wars, which sting Ryoubi and Ryouna several times, giving them a horrible pain.
After taking ten of stings, the water tornado violently throw them on the wall, Ryoubi is KO, but not Ryouna.
"Still standing up? Not bad…"
Ai tells Ryouna with a sinister smile.
"It felt so good! Now, I can be serious…"
Ryouna claims while moaning of pleasure, which first surprise Ai because she forgot Ryouna was in that side. But then, she realizes something, something she finds pleasant.
"So, you consider your pleasure as more important than your sister well-being? That's not very… Kind… Are you sure you love her?"
Ai asks by smirking, but she's astonished when she hears someone else answering.
"Of course she does, she just trusts me… It's not you or your ridiculous jellyfishes that can beat me!"
Ryoubi proudly yells while standing up.
But Ai quickly smirks again, and admits something to her opponent.
"Those "ridiculous jellyfishes" like you say have injected a powerful and mortal toxin inside you, so, you're kind of already dead… Hihihi…"
Ai tells the twins, who immediately look afraid when they hear these words.
Ryoubi is scared by the idea of being doomed to die and tries to reassure herself as much as she can.
"Y-You're lying!"
Ryoubi screams, but that only makes Ai smiling even more.
"She's not…"
Ryouna says in a pretty low and serious voice.
"Uh?"
Ryoubi reacts, confused.
"My body… I can feel it being consumed by a disease… She didn't lie…"
Ryouna explains, breaking her sister's last hope.
And Ai, by seeing the faces full of despair of her opponents, can't help laughing.
"Hahaha! Sorry, but I'm like way too strong and smart for you! I'm the best shinobi of this school, none can defeat me!"
Ai yells in an arrogant voice.
Ryoubi, by hearing Ai boasting, is invaded by hatred.
"You still need to prove it… But you won't be able to… CAUSE YOU'RE GONNA DIE WITH US, BITCH!"
The sniper yells, which makes Ryouna confident again, enough to stand up to launch an attack.
"Secret Ninja Art, Skater's Waltz!"
Ryouna yells, charging her energy before gliding in Ai's direction, but she doesn't intend to let her be.
"Secret Ninja Art, Cruel Water!"
Ai yells while turning her whip into a gigantic water whip, which she uses as a lasso to catch Ryouna to stop her using her art.
"Secret Ninja Art, Ricochet Prelude!"
Ryoubi screams before shooting bombs in front of her, but before they could join Ai, the cruel shinobi launch Ryouna right on them, making them explode under the shocked eyes of her sister.
"You should make your arts simpler, I could have countered it at least five times…"
Ai says in an arrogant voice, but Ryoubi ignores her.
"Ryouna!"
Ryoubi screams, worried, but her sister seems to enjoy what just happened, which makes her sister angry as hell.
"So good!"
Ryouna screams.
"Stupid dog…"
Ryoubi says in a very annoyed voice, but she decides to ignore her sister and to focus on Ai, who's already using another attack.
How Ryoubi knows it? A threatening cloud has appeared above her and her sister, who also feels something bad is coming.
"Secret Ninja Art, Hangman's Rain!"
Ai yells in a sadistic voice, following those words, Portuguese man-of-wars start to fall on Ryoubi and Ryouna.
However, those man-of-wars are different, the venom isn't the same. It's way less venomous, but way more painful, to the point Ryoubi passes out again.
But Ryouna isn't…
"It's so good… I feel great again!"
Ryouna yells before using her Frantic mode, which surprises Ai.
"Ultimate Secret Ninja Art, Rebellion Concerto!"
Ryouna yells, unlike she usually does, she focuses her shoots on a single place, where Ai is.
Ai does her best trying to stop all the bullets by twirling her whip in front of her, but some manage to pass and touch her, including one that pierce her abdomen.
It's not a big deal for a shinobi like Ai, but the sudden pain makes her closes her eyes… And Ryouna is gonna use this opportunity to finish her show.
She jumps to arrive just in front of Ai and summons an ice-made winged pig that immediately freezes her.
Ryouna takes a look at Ai, jailed in the ice, but not for long…
Crack
The ice cracks, and one second later, it shatters.
"Not bad at all! Secret Ninja Art, Cruel Water!"
Ai screams by smirking before reusing her art to directly hit Ryouna this time, ripping off her shinobi suit to the passage.
Ryouna screams of pleasure, but her body can deal with any more damage, she falls and stays in the ground.
"Hahaha! Seems I'm really the best shinobi there!"
Ai yells in a proud voice.
"No, you're not…"
Ryouna says in a low voice, and before Ai could make fun of her, she adds:
"A shinobi is someone who fights in the shadow to protect people from Yôma… And I doubt you can protect anyone…"
Ryouna explains before passing out.
Ai is furious and want to quickly finish Ryouna, which would be a crueller punishment for a masochist like her.
But when she tried to advance, she notices she cannot…
Because her right leg is trapped in the ice.
"But how…"
Ai starts, but a fire shot interrupts her…
"What?!"
She screams, surprised.
It's Ryoubi, who's waken up, and who just shot Ai.
But…
"W-Why?"
Ai asks, confused.
Indeed, Ryoubi didn't shoot Ai's body, but the ice blocking her leg, which destroyed it.
So, Ai is free to move now.
"The plan was to make you unable to move, so I could kick your ass, but it wouldn't have been satisfying…"
Ryoubi says by prondly smiling.
"Are you retarded or? It was a golden opportunity…"
Ai respond in a scornful voice.
Ryoubi is gritting her teeth, as if she was annoyed.
"You didn't listen…"
She says in an irritated voice.
"What?"
Ai asks, confused again.
"I told you we refuse to live likes bitches… SO THERE'S NO WAY I UNFAIRLY BEAT YOU!"
Ryoubi yells while activating her Frantic mode.
Ai smiles by hearing what she considers as a foolish act.
But… In a way, she's also curious to see how much time Ryoubi can last with her pride.
Pride Ai can't wait to wreck.
"Secret Ninja Art, Hangman's Rain!"
Ai says by summoning her cloud again, but Ryoubi this art now, and an art can work twice on a prepared shinobi.
"Secret Ninja Art, 8 Minuet!"
Ryoubi yells while shooting above her to summon bombs, but this time, she directly makes them explode in the air in order to destroy Ai's cloud.
Boom
And it works, which astonish Ai.
Ryoubi is now about to use her ultimate attack…
"Ultimate Secret Ninja Art, Minuet Missile!"
Ryoubi yells before summoning her missiles launcher device.
Without warning, she opens the fire on Ai, who's preparing her defence.
"Secret Ninja Art, Cruel Water!"
She yells before reusing her water whip, this time to destroy the missiles coming for her.
Ryoubi then launch another burst of missile that fusion in the air to make a single bigger one.
Ai tries to counter it, but…
"Oh shit… Shit!"
Her water whip disappears, she's used too much shinobi force and Ninja Arts during this fight, so, her art ended too quickly…
...And she hasn't enough time to dodge the rocket…
Boom
"UHAAAAAAA!"
She screams, directly hit in the abdomen by the explosion and blowing off.
Ryoubi is exhausted, but she also knows she can't allow herself to take risks with Ai, so, she decides to finish her…
At least, that's what she planned…
"W-What… Wrong?"
Ryoubi says in a low voice, she feels dizzy.
She remembers something, the venom. It's starting to seriously affect her body.
And is it wasn't enough…
"You forgot it… Didn't you? You're really… Stupid…"
Ai says, walking toward Ryoubi with difficulty.
Her abdomen is wounded, but it doesn't look lethal, at least, not for a shinobi like Ai.
Ryoubi doesn't know what to do, Ryouna is still KO and even if she wasn't, she wouldn't be able to do something too.
She's not even able to keep the shinobi barrier active, it disappears.
"Fuck… You're hard to kill…"
Ryoubi says, trying to stay strong.
Ai is still smiling, and takes a tantô to terminate her opponent.
"Thanks for the compliment! Um… I admit you weren't bad yourself, too bad you let good weakening you…"
Ai says by sighing, then prepare the final strike.
"Farewell!"
Ryoubi accepts her faith and close her eyes, but the strike doesn't come…
She slowly opens her eyes, to face a shocked Ai, but also another person.
"W-What?"
Ai says with surprise when she sees a familiar person firmly holding her arm.
It's Yû.
"Stop…"
She firmly orders her comrade before throwing her to make sure Ryoubi is out of her range.
"Kya?!"
Ai screams, but easily rights herself.
Then, one of Yû's dogs joins Ryoubi and offers her a paper bag.
"Syringes, they contain the cure for Ai's venom, take them."
Yû coldly tells Ryoubi.
Ryoubi, by reflex, takes the bag and looks inside, Yû didn't lie, it does contain syringes.
"O-Okay…"
She says, doing her best to stand up and join her still unconscious sister.
Ai is shocked, Yû just betrayed Hamato whereas she thought she would be the last one to do that.
"What the fuck are you doing?!"
Ai asks in a both angry and shocked voice.
"I'm putting an end to that fight."
Yû answers, but it only makes Ai even more furious.
"I was about to win! Do you even realize you're betraying our school and master Hamato?!"
Ai yells, but it doesn't distrurb Yû.
"I am, But I understood something… We can't just obey Hamato without even knowing his motivations. Don't you think that, as elite students, we have the right to know?"
Yû asks, she's way more talkative than usual.
Ai is confused, she cannot say she doesn't understand Yû's concerns.
But it doesn't mean she agrees with her…
"Why? We have a job, we obey, nothing more. You were the first one to say that a few hours ago…"
Ai says by looking at Yû with scornful eyes.
But Yû still has something to tells her…
"What you think Heitan would say?"
Yû asks, that question shocks Ai, who stays quiet.
"..."
But only after a few seconds, she gets angry, very angry…
"You mean the bastard who abandoned me… Us? I don't give a fuck about his opinion!"
Ai yells before rushing to Yû and stabbing her heart.
"Ghu…"
Yû reacts, shocked.
Ryoubi, who was looking the scene while injecting the cure to herself, is shocked too. She wasn't expecting Ai to still be able to move that quickly.
But the strangest thing is that Ai also looks shocked by her own act, and in a bummed voice, she says:
"I curse you for what you made me done, Yû…"
But Yû doesn't plan to just die, and answers:
"Same…"
She says before catching Yû to immobilize her.
"Huh?"
Ai reacts, and before realizing what is going on…
"Ultimate Secret Ninja Art, Loyal Dog's Canine!"
Yû yells, mobilizing her last forces to use her ultimate art under Ai's confused eyes.
"Crap…"
Ai says without real emotion in her voice before the rock made jaw crush both her and Yû.
Ryoubi covers her eyes to avoid having slivers of rock in her eyes, and once the scene visible again.
Yû is inert, died instantly… Her dog has already joined her, and it seems he understands its mistress is gone, according to the sorrowful noise of it…
But Ai isn't dead, even if it's just a matter of seconds…
"W-Why it ended like this?"
Ai asks, staring at the ceiling with bummed eyes.
Ryoubi is hesitant, but she finally decides to give her an answer.
"You underestimated good, that's all…"
She tells the dying shinobi.
Ai doesn't react first, but after a brief moment of reflection… She smiles.
"Seems so…"
She says before closing her eyes… And passing away.
Ryoubi feels no glory despite her victory, and without looking behind, she returns to her sister's side, who looks about to wake up.
The four students of the senior elite squad dead, the only enemy remaining is Hamato, who should be dealing with Homura and Miyabi now...
