Summary
With Sanji's secret finally out, the Straw Hats realize that they're woefully unprepared to deal with the only omega on the crew, leading to a tense meeting that leaves no one happy as they approach their next destination. They arrive at Delilah Island with Sanji stuck on the Sunny, while the rest get to explore and relax on the seemingly boring port town (and ignore the gnawing guilt).
However, they realize that the island is stranger than expected: A place where alphas are considered second-class citizens, and is currently affected by a string of violent incidents. They soon find themselves wrapped up in the mystery, with Zoro right in the center of it, and must solve the case before time runs out.

Summary
My attempt at playing with alpha, beta, omega, and delta dynamics, as we go through Sanji's journey of reconciling with his omega designation after denying/hiding it for decades since escaping Germa.
Ideally I'll get to ZoSan children, but let's just take it one fic at a time...!
Will be primarily ZoSan with hints of other couples
Will alternate between second gender and designation throughout this series- Words:

Summary
A raised penpoint declares mutiny against normalcy. It builds a story army of words, phrases, sentences with the single ambition to challenge established standards.
Though, the greatest adversaries are none other than the writer's own preconstructed limitations.

Summary
“Which one is this?” Zoro asks, peering down at his plate. He sounds almost bored, like he’s speaking to someone—something—not even worth his time. Something that’s only there to elicit a response so he can properly enjoy his meal.
Rule three: only speak when prompted.
“Hamachi,” Sanji replies.
