Ep 1. Start

BTOOOM! season 1 episode 1, titled "Start," introduces the audience to the world of the show. The episode opens with the main character, Ryota Sakamoto, playing a popular online game called BTOOOM! on his computer. Ryota is an expert player of the game, and he spends most of his time playing it. He is a top-ranked player in Japan and has earned some money from his skills.

One day, Ryota wakes up in a strange place, surrounded by complete darkness. He has no idea where he is or how he got there. Suddenly, a small light turns on, and Ryota sees that he is in a strange room with a door locked from the outside. With no other choice, Ryota turns on his game-sense and starts to think of a way to escape. In the room, he finds a few basic supplies, such as a knife, a backpack, and some rations.

After some searching, Ryota realizes that he is on a deserted island and the game he's playing is no longer just a game. He is now a real-life player in the game of BTOOOM! and must fight for survival against other players who are also trapped on the island. Each player has a set of bombs that they can use in various ways to defeat their opponents and become the last one standing.

The players are chosen by an unknown force and are taken to the island to play the game. The only way to escape the island is to win the game by killing the other players. Ryota is shocked and terrified by this realization. He has never killed anyone in his life, and now he is forced to survive by killing other people.

In the first episode, Ryota meets another player named Himiko who is also stranded on the island. She tells Ryota that she has been on the island for several days and has already killed two other players. She warns Ryota that he can't trust anyone on the island and that they are all fighting for survival.

Ryota is initially hesitant to believe that he's really in the game and that he has to kill others to survive. However, when he encounters his first opponent, who is also a player in the game, he realizes that the threat is real. The episode ends with Ryota and the other player facing off against each other in a battle for survival.

Overall, the first episode of BTOOOM! sets up an intense and suspenseful story about survival and betrayal. It's an interesting mix of action, adventure, and psychological thriller that keeps the audience on their toes. As the player characters are introduced, the audience is left to wonder who will come out on top and whether Ryota will be able to trust anyone on the island.
