One Piece Luffy's sister: Your Guardian Angel

Savin Nami and Mikasa's limit.

The next day

Mikasa was still sitting next to Nami.

She hasn't been sleeping the night.

She either cooled Nami's fever or kept her warm or meditate while keeping an eye at Nami.

She finally fell asleep in the morning but was woke up roughly by loud yelling from outside.

Mikasa looked at Nami and noticed that she looked even worse than the day before.

Mikasa walked outside to see Luffy blow away someone. "What's going on here?" Mikasa said tired and irritated.

"Some stranger guy was walking on water first and then started to eat going Merry," Luffy explained.

"Anyway, how is Nami?" Sanji asked.

Mikasa sighed." She looks even worse than yesterday." she said.

"How about you?" Zoro asked.

"Yeah, have you at least slept for a few hours?"Usopp asked her.

Mikasa shook her head. "No... actually, I was sleeping a few minutes ago. But I didn't sleep all night. I watched over Nami." she said.

"Maybe we should dump a bucket of water on Nami to cool her down," Luffy suggested. Sanji and Vivi hit him on top of his head.

"We should put the anchor down, sailing without Nami's navigation would be too dangerous," Vivi said.

Mikasa nodded. "I guess I should head back to her."But she was stopped by Zoro.

"You should rest for a while. Nami is going to be fine." Zoro said.

"I'm not leaving Nami's side until she's feeling better and I'm not going to rest. "She said walking back to sit on the floor next to Nami's bed.

Everyone looked at her worried. "She's going to kill herself if she's going to continue being that protective over us. "Zoro said shaking his head.

Later that night

Everyone already fell asleep except for Sanji who was on lookout and Mikasa who was still mediating next to Nami.

"Mika." She suddenly heard Nami's voice.

"Nami," Mikasa said smiling softly. "How are you feeling?" She asked feeling Namis forehead and frowned a little bit."You're still warm." She said.

"How long have I been sleeping?" Nami asked.

"Two days," Mikasa answered.

Nami looked concerned at Mikasa. "You look just as terrible as I'm feeling. Have been sleeping at all and how long are sitting here next to me?" Nami asked her worrying.

Mikasa smiled at her. "Don't worry about me Nami. I... slept the whole day and I'm just sitting here... like two or three hours maybe longer. " Mikasa said.

Nami was about to open her mouth to say something. "Nami, I'm fine," Mikasa smiled.

The next day.

"Thank you, Sanji," Mikasa said as Sanji brought her a cup of coffee.

"You're welcome, Mika. I know you didn't sleep another night." He said.

Mikasa looked at Nami. "I can't sleep quietly while she is clearly in pain. I have the power that can at least help her a bit so I'm going to use it as long as she needs it. Besides, I was meditating the whole night and now I'm drinking coffee. So, I'm not that sleepy." Mikasa said as she and Sanji walk outside.
