Got it.
I'll write Chapter 14 and Chapter 15 separately, focusing on:
Kaien's retaliation

The Calm Before the Storm
Hana walked beside me through Konoha's training fields, her injured arm now fully healed.
"Feels like we can breathe for once," she said softly.
"That's what worries me," I muttered, scanning the treeline.
---
The Ambush
Before she could respond, chakra flared—fast, vicious. A black-clad figure lunged, striking Hana with a stunning seal before I could react.
"Kaien sends his love," the attacker hissed before vanishing with Hana into smoke.
"HANA!" I roared, storm chakra exploding around me.
---
The Clue
Kai and the team arrived seconds later.
"They used an advanced teleport seal," Sera said, kneeling. "They left… this."
It was a note: "Come alone, Arashi. Or she dies."
---
The Resolve
"I'm going alone," I said firmly.
Kai stepped forward. "Like hell you are—"
"This is personal," I snapped, eyes glowing faintly with storm energy. "No one touches her and walks away."
---
Cliffhanger
The note's location was a decrepit shrine outside the village—a perfect trap. I stood at its gates as thunder rolled overhead.
"Kaien," I growled, activating my new jutsu. "Tonight you pay."
---
The Shrine Battle
Kaien himself stood at the shrine entrance, Hana bound behind him with chakra chains.
"You've grown strong, Arashi," he sneered. "But love makes you weak."
"Funny," I said, storm chakra swirling around me, "because it's about to end you."
---
New Jutsu – Tempest Wrath: Dragon Fang
I slammed my hands together.
"Tempest Wrath: Dragon Fang!"
A massive dragon of storm chakra erupted, twisting around me before lunging at Kaien, shattering his defenses and blowing him back through stone pillars.
"Impossible!" he shouted, staggering.
---
Hana's Moment
Even bound, Hana managed to channel her Chakra Bloom through the chains, snapping them.
"You think I'm helpless?" she yelled, striking Kaien with a blinding chakra petal storm.
---
The Finish
I appeared in front of Kaien, Falcon Strike aimed at his chest.
"This ends now!" I shouted, striking him square and sending him crashing into rubble unconscious.
---
Aftermath & Promise
Hana stumbled but caught herself. I caught her wrist, pulling her close.
"Are you okay?" I asked.
She smiled faintly, eyes shimmering. "I am… because you came."
"From now on," I said, taking her hand fully, "we face everything together. Partner?"
"Partner," she whispered, leaning her forehead to mine.
---
Cliffhanger
As ANBU reinforcements arrived, Hana and I stood hand in hand, unseen under the stormy sky.
Kaien was down, but something told me… his network wasn't dead
