Mermaid Princess and the Sea Legend
It's a normal and boring day for one specific underwater creature until a shipwreck has come across her vicinity, falling in love with the man swept across the debris. Wanting to help him the best she could, she enlists the crew's help after hearing about their stories through word of mouth.
What was supposed to be a normal vacation ends up creating curiosity when the crew finds a seashell requesting help for one specific man and an upfront payment of one pearl. While the man seems to be fine regarding to his health, it turns out that there's something else the crew could help him on, training him to be a worthy sumo wrestler as worthy as Yokozuna.
Tropes
- Achievements in Ignorance: As the rematch between Raiden and the merfolk king goes on, the two managed to evaporate the entire sea to the point that Seofon considers the former to be a potential threat.
- Combat Pragmatist: The merfolk king has no qualms about using dirty tactics to win in a sumo match like eye poking and doping.
- Defeat Means Friendship: Raiden's first interactions with the crew isn't as smooth due to being upset over his lost boat and is fueled with revenge. It takes one bout for him to clean up his act and asks them for proper training.
- Double Meaning: At one point, Thalassa remembers her father doing a tsuppari thrust and utters its name. It didn't take long for Tsubasa to hop in on the conversation since tsuppari also refers to delinquent youth like him.
- The Exile: Raiden chooses to take all the blame regarding to the evaporation of Auguste's seas, telling the Chief to exile him from the island.
- Fire-Forged Friends: Raiden tells Tsubasa to not interfere with his training, causing the two to duke it out. The two got through what they meant through the fight, calling each other friends shortly after.
- Let No Crisis Go to Waste: When word came by that a kelp fiend wielding a demon sword is causing havoc, Raiden takes on the task by himself, also because he wanted a harder challenge at that point.
- Magical Defibrillator: After Raiden lost to the Albacore, Albert gives him the push by shocking him twice: once to get him back and another to stimulate his muscles.
- Significant Wardrobe Shift: After his victory against the merfolk king, Raiden's mawashi starts to flash and gives him additional clothing.
- Took a Level in Badass: At the start, Raiden is just one person living in a secluded and small island. By the end, Raiden becomes a worthy successor to Yokozuna and can do remarkable feats that sparks the crew's awe.
