One Piece Luffy's sister: Your Guardian Angel

Meeting Chopper and arriving at Alabasta

Flashback

"What were you thinking?!" Garp yelled as he sat on the bed next to Mikasa.

"I thought I was ready to use two powers at the same time." She said.

"Your powers are way too strong for your body. You have to be careful." Garp said.

"Says the person who left Luffy alone in a Jungle for a whole week. " She argued.

"He's strong and he's a big boy already. I have to train him. So that he and Ace both can join the Marines." He said.

"He's my little brother and your grandson. I promised Mom to protect him. I have to be stronger so that no one will take him away from me... not even you." She said weakly.

"He doesn't need your protection. Besides, it doesn't mean you have to kill yourself." Garp said.

"I know he doesn't need me. But I need him. Besides how bad can my powers be for myself." She said.

"Your body can't take the high temperature or the low temperature you use for fighting. Your body has to get used to it slowly. Your whole body and your organs they either start to freeze or the start to boil. If you continue to use your power in such a reckless way. You'll die. And then you won't be able to protect him anymore." Garp said.

Mikasa lied there for a minute before nodding. "Okay, I will be more careful with my powers next time." She said

Flashback end

Mikasa opened her eyes and looked around.

"I see you woke up." Dr Kureha said.

Mikasa sat up immediately. "Where's Nami? Where's Luffy? Where's Sanji? Are they alright? Can I see them?" Mikasa asked.

"Shut up will ya? They are all fine. Your sister woke up a few minutes ago. Your brothers are still asleep." Dr Kureha said annoyed. "You should actually care about your health more. I have no idea what you did to yourself or what your powers do. But your organs were cold as a dead corpse. The strange thing is that your body got used to it. It didn't shut down. " She said.

"So, am I able to use fire and ice at the same time?" Mikasa asked here.

"Probably but only for a short time. If you cross the limit a few times ...you'll die a very painful death." Dr Kureha said.

"I know. However, can I see Nami?" Mikasa asked here.

"Do what you want." Dr Kureha sighed.

Mikasa walked towards Nami's room and suddenly Luffy and Sanji ran out. They were running after some kind of animal. She also heard Nami yell after them.

"I see you. You're feeling better." Mikasa said smiling leaning against the doorway.

"Mika! You're awake." Nami said grinning. "

Yeah, just woke up a few minutes ago." She said as she sat on the bed.

"How are you feeling? I heard you brought us here." Nami asked here.

"I'm fine Nami. Besides, Luffy carried you and Sanji much longer then I did. I just helped a little at the end." Mikasa said smiling.

Suddenly a weird animal came in.

"Nami, who's that?" Mikasa asked.

"This is Tony Tony Chopper. He's a reindeer that ate a devil fruit and transformed into a human form. He's a doctor. "Nami said.
