🔹 “Science and desire are two sides of the same coin.”

Relationship: Mutual respect, competitive and complementary.

From the moment he wakes up, Ryusui recognizes Senku as someone extraordinary, worthy of following… but also worthy of challenging.

Although they clash constantly (Senku is pure logic, Ryusui is pure ambition), they both drive each other to be better.

Ryusui sees Senku as an “equal,” someone who shares his vision of conquering the world, not out of power, but out of curiosity and progress.

You could say that Senku represents the scientific mind, and Ryusui the human spirit that drives it.

Throughout the series, Senku fully trusts him to lead the crew, even when his decisions seem risky.

💬 Phrase that defines them:

Senku: “With science, we will conquer the world.” Ryusui: “And with desire, we will enjoy it.”

Ryusui, although he usually treats everyone with a certain superiority, speaks to Francois as an equal, demonstrating how much he values ​​his judgment.

They both share a vision of perfection and refinement, both in science and in the art of living well.

💬 Highlight: When Francois revives, Ryusui smiles and says:

“With Francois by my side, the Scientific Kingdom will finally be able to taste true civilization.”

Gen and Ryusui understand each other very well: both are charismatic manipulators who know how to influence people.

When working together (such as in a poker game or negotiations), they combine Gen's charm with Ryusui's audacity, becoming a dangerously persuasive team.

Although Gen jokes about his “arrogance,” he admires him for his vision and follows him because he knows Ryusui has the ability to make things happen.

Ryusui also values ​​Gen because he understands his mental game and doesn't underestimate him.

💬 Typical dynamics: Gen: “You are shamelessly ambitious, Ryusui.” Ryusui: “And you’re shamelessly helpful, Gen. We get along well, don’t we?”

Relationship: Professional respect and camaraderie.

Kohaku initially considers him to be somewhat arrogant and conceited, but soon recognizes his leadership, courage, and vision.

Ryusui respects her for her strength, loyalty, and courage.

On missions, he trusts her completely as a guard and companion.

Although there is no romantic bond, there is a friendly tension based on mutual admiration.

He enjoys her openness, and she appreciates his fearless confidence.

💬 Example: When Ryusui offers to take control of the ship during a storm, Kohaku supports him without hesitation, saying:

“If anyone can steer this ship, it’s him.”

In several scenes, he encourages her and teaches her things about sailing or exploration, treating her like a “little adventurer.”

Suika also deeply admires him and strives to understand his way of seeing the world.

💬 Example: When Suika offers to help with chores around the ship, Ryusui smiles and says:

“That’s the spirit of exploration. Desire has no age, Suika.”

Ryusui and Chrome – The spirit of shared discovery

🔹 “Two dreamers, one of science and the other of adventure.”

Relationship: Of companionship and mutual respect.

Chrome admires Ryusui for his determination and bravery, while Ryusui respects Chrome's scientific instinct and natural curiosity.

They both share the idea that limits exist only to be surpassed.

On several occasions, they work together on experiments or practical projects (such as propulsion, resource management, or materials organization).

Ryusui considers him a “younger brother in spirit,” and Chrome sees him as a model of energy and ambition unafraid of failure.

💬 Example: Chrome: “I can’t believe you tried that without knowing if it would work!” Ryusui: “That’s the fun of it, Chrome. If you already know the outcome, there’s no adventure.”

Episode 1: “Ryusui vs Senku” – What Ryusui Did

In the first episode of Season 4, Ryusui plays a prominent role from the very beginning of the journey. Here are the key points:

1. Take the route to cross to the New World (North America):

After setting sail from Tokyo on the ship Perseus, Senku and Ryusui clash over which route to take to get to San Francisco.

Ryusui proposes using the Rhumb Line, a more direct route on flat maps, which would take longer but would be less tiring for the crew.

Senku prefers the Great Circle Route, which, while it “curves” across the planet’s surface, is shorter considering the Earth’s curvature, which would save them days of travel.

2. The duel between Senku and Ryusui:

To decide the route, Ryusui challenges Senku to a "non-physical" confrontation, but rather an intellectual/strategic one. They decide to settle the matter with a game of poker.

Ryusui chooses Gen as his partner, while Senku chooses Kohaku.

During the game, Ryusui is winning chips and betting heavily. But Senku has a strategy: he marks some cards using invisible lacquer (urushi), which allows him to know which cards to draw. Although it's dangerous for him (because Senku is allergic to urushi), he does it to ensure his victory.

In the end, Senku wins the game with a very strong hand (a royal straight flush). Ryusui concedes the choice of route, but sets one condition: that the crew must be provided with amenities on the trip (creating recreational areas, a bar, a casino, and improving group morale).

3. Ryusui's character dimension shown:

His concern for the crew is evident, not just his ambition. He doesn't want to put the team at risk, but he also wants efficiency.

Also his sense of leadership: he doesn't accept anything being imposed without dialogue; he seeks consensus even when he's certain of his own position.

His cunning: He uses his negotiating skills, bets, conditions, and comforts to influence. He doesn't give up easily.

“Ryusui’s Awakening”

Senku, Chrome, and the others seek to expand the reach of the Science Kingdom into new territories, but realize they need to sail across the ocean.

Thanks to a statue found intact, they decide to revive Ryusui Nanami, a famous navigator from the ancient civilization.

“I wish for everything the world has to offer!”
