One Piece Luffy's sister: Your Guardian Angel

The Grand Line

"The light from the lighthouse should not disappear. We could get lost." Luffy said.

"That's why I'm the navigator. It's my job to remember the way to Grand Line." Nami said.

Mikasa was quiet she started towards the sea and then on her hands. She thought about what happened at Loguetown.

"Stop!" She yelled and lightning strikes Buggy.

Was this lightning caused by me or was this just coincidence? She thought. Dad was also there. She thought as she remembered the tattoo on the person's face that saved them from Smoker. Could he have to do something with it? She thought.

"Mika?" Zoro called her. She turned around and saw the worried looks of her crewmates.

"Are you okay?" He asked her.

"Yeah, I'm fine I guess.. just thinking." She said smiling again.

"The entrance to the Grand Line is the Reverse Mountain on the Red Line," Nami said.

"Mountain? But's it's impossible to climb a mountain with a ship. Is the Map even accurate?" Usopp wondered confused.

"I want to get to that magic mountain!" Luffy yelled excited.

"We should enter the Grand Line from the south," Zoro suggested.

"No, we have to enter the Grand line from the mountain because it's cooler this way," Luffy said cheerfully.

"Of course he does," Nami said shaking her head. Mikasa chuckled slightly.

Suddenly the weather calmed down.

"We need to head towards the storm in order to arrive at the entrance," Nami said irritated.

"But we are in the Calm Belt, right?" Mikasa asked her.

"The Calm Belt. How did I didn't think about this sooner." Nami said facepalming herself. "Everybody we have to row," Nami ordered.

"But this isn't a rowboat, Nami," Usopp said.

"We are in the Calm belt there is no wind here." She explained.

"Mika, can't you do something? I mean you can control elements. Can't you also use wind?" Usopp asked her curious.

Mikasa looked at him before shaking her head. "No, my elements are based on my personality. The fire is my passion, my anger, my determination. The ice is my calm, my coldness, my stubbornness. And lightning is the balance between fire and ice. So, no I will never be able to use wind as an element. " Mikasa said.

"So, we have to row?" Zoro said rolling his eyes.

"Yep," Mikasa said sheepishly.

The ship shook suddenly. "What's going on?" Usopp said nervously.

"We are surrounded by sea kings," Mikasa said staring at a sea king who looked angry at them.

It looked like it was about to open his mouth to bite. But Mikasa glared at it softly. "Back off!" She said stern and the sea king stood back.

After a few moments, they are back to the storm.

"Do you understand why we have to go through the mountain marimo?" Mikasa said smirking at Zoro.

Zoro nodded. "Yeah, I do. shorty." He said.

"The waves of the fours seas gather here to create steam. The steam would push the mountains canal and when the water has reached the mountain's peak it will push back to the Grand Line." Nami explained.
