The next day, Kav's injuries have healed. After her sword training and kicking lessons, Luffy ran over to her.

Luffy: Kav!

Kav: Yes, Luffy?

Luffy: Fight me!

Everyone except Luffy and Kav: What?!

Kav: Alright!

Everyone except Luffy and Kav, and Robin face palmed.

Nami: That's three days in a row now.

Luffy: Kav, let's start!

Kav: Alright!

Luffy: Use the back of your sword, I don't want you two cut off my arm.

Kav: Ok!

Luffy and Kav's battle has already passed two hours.

Luffy: Gear second!

Kav thought to herself: "Oh shit! I have to do something, but what?"

Luffy: Here I come!

Kav: Oh man!

Kav was full of anger and determination that she doesn't want to lose. Suddenly…

*ROAR!* Kav blew fire out of her mouth while she roared. Everyone was stunned.

Usopp: What?!

Chopper: She blew fire out of her mouth!

Nami: No way!

Kav: That's strange. I never blew fire out of my mouth before.

Luffy: Awesome! Kav, how do you do that?

Kav: I don't know. I've never done it before.

Robin: Maybe it was from the tiger.

Nami: That's crazy, Robin. How can a tiger blew fire?

Kav: Hm… Now that you mention it. I do remember the tiger did blow fire to me once.

Nami, Usopp and Chopper: What?!

Luffy: Cool! Now Kav is a fire breathing tiger-eyed kicking swordsman!

Kav: That's so long, Luffy.

Sanji: Haha, what a talented girl.

Zoro: Impressive.

Brooke: Yohohohoho, she now has so many skills.

Franky: She's super skilled.

Kav: Shall we continue?

Luffy: Sure!

Fire was coming out from Kav's leg. She intended to kick Luffy, but he invaded it.

Luffy: It was like Sanji's leg!

Sanji: No way! How can you do my Diable Jambe?

Kav: I just do it, I guess. Nice dodge, Luffy. Now, let me try something.

Kav's sword started to lit up with fire.

Kav: Sweet!

Luffy: There's fire on the sword.

Usopp: No way!

Nami: How can this happen?

Kav: One must be one with their sword. Am I right, Zoro?

Zoro just smiles to her.

Kav: Now I can use fire sword style. Be ready, Luffy!

Luffy: En!

Later, the battle ended. Luffy and Kav was lying on the floor panting.

Luffy: That was amazing! I'm hungry! Sanji, Food!

Kav: Well, I'm exhausted.

Usopp: K-kav is on par with Luffy?!

Chopper: She's also on par with Zoro and Sanji!

Nami: She's on par with the monster trio!

Robin: She's strong like them.

Franky: She's a suuuper monster.

Brooke: Yohohohoho, that's amazing!

Usopp: I think now we have a "monster foursome".

Chopper: Yup. I'm glad she didn't fell unconsious again.

Nami: You're right.

Kav gets up from the floor and walks over to Nami.

Kav: Nami.

Nami: Yeah?

Kav: When are we going to get to an island?

Nami: By tomorrow morning. Now go rest. You need it.

Kav: Ok!

The next day, the crew reach an island that is on fire.

Nami: It's so hot!

Usopp, Chopper and Luffy lies on the railings.

Usopp: It feels like I'm melting.

Chopper: Me too.

Luffy: Water!

Kav: Woah, it sure is hot!

Luffy sees Kav standing on the fire.

Luffy: Kav, you're on fire!

Kav: I know.

Usopp: How can you even stand at there?

Kav: Cuz now I have fire power.

Usopp: Oh.

Luffy: That's so cool!

Kav: Sanji! Zoro!

Sanji: Yes?

Zoro: Yeah?

Kav: Want to come down and take a walk on the island?

Zoro: Sure!

Sanji: Why not? Just wait a sec.

Sanji spins and made his leg on fire to walk on the land.

Sanji: Ok! I'm done.

Just before they were off, Robin calls out to Kav.

Robin: Kav.

Kav: Yeah, Robin?

Robin: Be sure not to go to the fire of memories.

Kav: It's just memories.

Robin: Those fires bring out your worst memories.

Kav: Oh! Well, I'll try to avoid them.

Luffy: Be careful, you guys!

Chopper: Have fun!

Kav: Yeah, bye!

And thus, Kav, Zoro and Sanji were off.

Kav: Zoro.

Zoro: Hm?

Kav: How come you can stand on fire?

Zoro: Well, I just wanted to stand on it and find myself standing doing it.

Kav: That's doesn't make any sense.

Sanji: He doesn't have any sense.

Zoro: What did you just say, Shitty Cook?!

Sanji: I said you don't have any sense, Moss Head!

Kav: Hahahaha...

Zoro: What's so funny?

Kav: Well, you two remind me of my brothers.

Sanji: Oh?

Kav: Well, we're not blood related but I treat them like my big brothers and they treat me like their little sister.

Sanji: How in fact that we remind you of them?

Kav: One of my brothers can use swords like Zoro and the other can kick like you, Sanji.

Zoro: So that's why you can do both.

Kav: Yeap.

Sanji: So where are they now?

Kav lowers her head and looks at the ground.

Kav: They…died five years ago.

Sanji: I'm sorry. I shouldn't have asked.

Kav: It's ok. I'm fine now. Besides, I have two persons that look like my brothers right in front of me.

Zoro: You can think of me as your brother, if you want.

Sanji: Me too.

Kav: Thanks, you guys!

Kav hugs Zoro and Sanji. They both hug her back. Then, Kav sees a dark red color flame and runs towards it.

Kav: What's that?

Zoro: Kav, wa-

Just as Kav touches the flame, she blacks out.

Sanji and Zoro: Kav!

Kav: Huh? Where am I?

Kav sees a figure of a person. She walks closer and notices that the person is her mother.

Kav: Mum!

She starts to run towards her mum. Suddenly, "slash!" Kav's mum is cut on the chest. She falls onto the ground. Kav immediately rushes towards her.

Kav: Mum, wake up! Mum!

Suddenly, the person that killed her mum is aiming at her.

Kav: No, stop this! No!
