Katya sat quietly as the others discussed strategy on the Den Den Mushi. Lost in her thoughts, she focused on the layout of the factory that was pinned to the wall. She made sure to memorise every corner, every hiding place she would be able to use in order to infiltrate the factory.

BOOM!

The earth began to shake and Katya fell over hard and landed on her back. Her necklace flew from her neck and the charm flew into the wall.

"No..." She picked up the pieces, looking down at the chain, which was three pieces. The stethoscope was warped and broken.

"Katya-chan, are you okay?" Robin said and walked over to her.

"My necklace..." she held up the broken pieces with a sob.

"Oh, is it a favourite of yours?"

"Law gave it to me a long time ago..." She murmured.

"I'm sure it can be fixed."

"I-It doesn't matter." Katya choked back a sob and clenched her fists in frustration.

"Oi, Zoro, I can't hear you properly." Franky said loudly, and she walked over to where the others were sat, determined to distract herself from the emotional blow.

"What's going on?" She asked.

"The town! It's like it's coming this way!" Zoro said on the other end of the line.

CRASH!

"Tra-guy!" Luffy's voice could be heard in the background.

"Stupid brat." Doflamingo could be heard as well and Katya tensed.

"Oi, Tra-guy, why are you with Doflamin-" Luffy began but then the next sound chilled Katya to the core.

A gunshot.

"You've pushed it too far." Doflamingo said coldly and fired again.

"TRA-GUY!" Luffy screamed in horror down the phone.

"NO!" Katya screamed. "LAW!"

The broken pieces of her necklace slipped out of her grip and fell to the floor.

Every bone in Katya's body had known that it was a bad decision, that she should stay put and help with the factory operation like Law wanted. But her heart and soul had burned with rage like she'd never felt before.

She had grabbed a Den Den Mushi and ran, but Robin had caught her and pinned her down. The group had left for the factory with Robin holding Katya in place as they raced down the narrow passageway.

"I'm sorry, Robin-san..." Katya sobbed. "I just-"

"I understand, Katya-san. But we need you for this mission. The others are retrieving Tra-guy, and he's not dead yet."

Katya nodded. "Robin-san, I need you to slap me."

"Okay." A sharp blow hit Katya's face and she cursed loudly. But she felt like she had snapped back to reality instead of drowning in her panic and grief.

"Thanks. Let's go."

Robin, Usopp and Katya entered the underground section of the factory where there were multiple cargo crates surrounding them. Leo and the others were being noisy, much to Katya's chagrin.

"Everyone, come here." Katya said. "I have a plan."

"Oh?" The tin soldier said.

"I've not done this very much, so it may not last, but I've been working on a new technique that can extend my 'Calm' ability. Usopp, can you come here a moment?"

Usopp warily stepped towards Katya and she focused before putting her hand on his chest.

"Calm!" The pulse flew out of her and Usopp flailed around screaming. But no sound came out as he did.

"You made his noise disappear!" Robin observed.

"Yes. I can't regulate how much of him is silenced, though. It's a very all or nothing technique. But if anyone thinks that they would be more stealthy with it, then I can use it on you! It lasts ten minutes each time."

Most of the Tontatta looked up at Katya in sheer awe.

"Katland is so cool!"

"It's like being invisible, but with sound!"

"Everyone! Tell me when you need it most, and I can make you the quietest humans alive! Now, let's go destroy this factory!" She said determinedly.

Law, Katya thought as the group followed her and Usopp further into the underground port. I'll complete this mission for us, so don't you dare die until it's done!
