Devious Pill

"Who else? I came here just to save your butt again," Number One commented and placed the pill on Luna's palm. "You owe me so many favors that I can't count it anymore." 

"What do you mean so many?" Luna argued right away while holding the pill as if it was a treasure. "It's only two so don't exaggerate. I already said I will repay you in the future." 

"Two?" Nami questioned innocently. 

"Luna agreed to be my servant for a month in exchange for high-ranked Soul Arts in the library," Number One explained simply and Luna immediately protested. 

"Hey, it was your idea," Luna countered. "I only said I can do anything." 

"I see. I wasn't aware of that earlier…" Nami muttered and assured Luna, "Don't worry, I'm a Soul King rank just like Number One so I can rent as many Soul Arts as I want. I will help you instead." 

"Huh?" That information caused Luna to look at them both speechlessly. "You two are both Soul Kings already? Since when?"
