Ep 1. The Contract Hidden in the Labyrinth

Being a genius is one thing, but being able to solve puzzles that could potentially put your life at risk is another. That's exactly what the protagonist Kaito Daimon does in the first episode of Phi-Brain: Puzzle of God. The show begins with Kaito entering a labyrinth that has been deemed unsolvable, but little did he know that solving the puzzle comes with a price.

The episode starts off with a game of chess between Kaito and his friend Nonoha, where Kaito once again proves his genius by winning the game in just a few moves. However, when Kaito's teacher Ryu Zaizen enters the room and asks him to solve a puzzle, he's met with resistance. Ryu is the head of the Puzzle Club at their school and has been seeking Kaito's help in solving complex puzzles.

Despite Kaito's initial reluctance, he finally agrees to help Ryu solve the mysterious labyrinth, said to have been built by a genius architect. As Kaito and Ryu venture into the labyrinth, they discover that it's nothing like they've ever seen before. The layout of the labyrinth is intricate and complex with a network of passages and rooms that are almost impossible to navigate.

As they make their way through the initial puzzles, they realize that they're running out of time, and a deadline looms if they don't solve the puzzle soon. The stakes get higher when they encounter a masked man who claims to be the labyrinth's guardian. He challenges Kaito to solve the final puzzle to gain access to the treasure that lies at the end of the labyrinth.

What Kaito doesn't know is that solving this puzzle comes with a contract – a contract that will place his life in danger. Kaito signs the contract without thinking about the consequences, but he soon realizes his mistake when he's trapped in the labyrinth with no way out.

The only way to escape is to solve the final puzzle, but the stakes couldn't be any higher. There's a series of trap doors, locked doors, and timed puzzles that Kaito has to solve to reach the treasure. Along the way, Kaito also discovers that there are others who have been trapped in the labyrinth and were unable to escape, including one of Ryu's classmates.

Kaito's genius puzzle-solving skills come into play as he attempts to solve each challenge in his way. However, the puzzles don't come without their consequences. Kaito and Ryu are faced with life-threatening situations, and it becomes clear that solving the labyrinth is not just about intellect but survival as well.

As the episode comes to an end, Kaito successfully solves the final puzzle and escapes the labyrinth, barely scraping through. However, the consequences of his actions still linger, as he soon discovers that the price of the contract he signed is higher than he thought.

Overall, the first episode of Phi-Brain: Puzzle of God sets the tone for the rest of the series. It introduces viewers to the world of puzzles and adventure that Kaito finds himself in, highlighting his intelligence and his ability to solve complex challenges. The episode keeps viewers engaged with an intricate plot, unexpected twists, and a thrilling journey through the labyrinth.
