Btooom!

Ryōta Sakamoto, a top-ranked player in the online deathmatch game Btooom!, finds himself trapped in a real-life version of the game after waking up to a bizarre new reality.

A high school girl finds herself caught in the deadly game of Btooom! after being betrayed by her neighbors and the group she allied with, leading her to lose trust in men.

Ryota encounters Taira Kiyoshi while searching for a mysterious girl, and Kiyoshi provides key details that help Ryota piece together his fragmented memories.

Kira Kosuke, a troubled child, finds his behavior increasingly uncontrolled on the island, where he can act without restraint. His unchecked actions come to a head when he confronts the top Btooom! player in Japan.

While eating lunch, Taira and Sakamoto notice a floating corpse, which prompts Sakamoto to investigate and discover a disturbing scene involving a person he recognizes.

Tensions rise between Taira and Sakamoto as their differing approaches to a crisis begin to strain their trust. Sakamoto's determination to save everyone, including a girl who recently attempted to kill him, creates friction with Taira's more cautious strategy.

Miyamoto, a ruthless mercenary, confronts Sakamoto and his team, introducing a new threat determined to achieve his goals at any cost.

Sakamoto and Himiko attempt to rest for the night, but Himiko is troubled by whether to reveal her true identity to Sakamoto. Before she can act on her thoughts, she is visited by a ghostly presence.

A new team member joins Sakamoto's group, but his mysterious background raises questions. Before the team can investigate further, a supply drop draws other players from the shadows.

The players on the island discover deeper connections among themselves, prompting Sakamoto to reconsider his understanding of the situation. Meanwhile, the doctor moves forward with his final plan.

Himiko becomes vulnerable after Ryouta's departure, making her a potential target for Date, though Shiki intends to use the doctor for his own purposes.

Taira's mental state deteriorates as he turns violent toward his friends, forcing Ryouta into a difficult position where avoiding conflict may no longer be possible.
