That familiar feeling of dread and excitement is creeping back in. The deck is being shuffled for one final, brutal game in the Borderland. When Alice in Borderland Season 3 drops, it won’t just be about new, twisted challenges; it’ll be a culmination of every relationship and survival story we’ve invested in since the beginning.
Knowing who’s playing the game both the familiar faces and the dangerous new wild cards is half the battle. So, let’s break down the full roster of players and antagonists for what promises to be an emotionally devastating and action-packed final season.
Who Are the Returning Main Cast Members in Alice in Borderland?

The heart of the story remains our core trio, whose bonds were forged in the fires of the initial games. Their return is non-negotiable, but their roles have evolved dramatically.
| Actor | Character | Their Journey So Far & Role in S3 |
|---|---|---|
| Kento Yamazaki | Ryohei Arisu | The brilliant but weary protagonist. After winning a peaceful life, he’s thrust back into the Borderland on a personal mission: to rescue the woman he loves. |
| Tao Tsuchiya | Yuzuha Usagi | The resilient mountain climber and Arisu’s anchor. Her abduction is the catalyst for the entire season, suggesting she’ll be more than just a damsel in distress. |
| Ayaka Miyoshi | Ann Rizuna | The sharp forensic expert. Her logical mind was crucial in solving the mysteries of the games. Her return suggests the new challenges will require serious brainpower to decode. |
| Nijiro Murakami | Shuntaro Chishiya | The cunning and morally ambiguous fan favorite. His return, confirmed by the actor’s presence, signals that his unique, self-serving strategies will once again shift the balance of power. |
But it’s not just the heroes coming back. The Borderland’s most chilling residents are also waiting.
| Actor | Character | Their Role |
|---|---|---|
| Hayato Isomura | Sunato Banda | The sinister antagonist with a warped sense of justice. He and Yaba chose to stay in the Borderland, making them seasoned veterans and formidable rulers of this hellscape. |
| Katsuya Maiguma | Yaba Oki | Banda’s ruthless partner in crime. Their continued presence establishes them as the de facto masters of the games that Arisu must now re-enter. |

Who Are the New Cast Members in Alice in Borderland Season 3?

Every new season introduces new players, and this one has a doozy of a villain leading the pack. The new cast is stacked with talented Japanese actors, though many of their roles are still deliciously shrouded in mystery.
The most significant addition is Kento Kaku as Ryuji. He’s not just another player; he’s the mastermind behind Usagi’s abduction. Described as a researcher obsessed with the afterlife, he’s the one who forcibly pulls Arisu back into the game. This gives us a human, intellectual villain far different from the game-centric Face Cards of before.
They’re joined by a formidable lineup of new players, including:
-
Koji Ohkura (The Monster Within)
-
Hiroyuki Ikeuchi (24 Japan)
-
Tina Tamashiro (The Flowers of Evil)
-
Kotaro Daigo (Weathering With You)
-
Hyunri (Tokyo Vice)
These actors will likely fill the roles of both allies and adversaries for Arisu as he navigates the Joker’s new set of games. Their presence ensures that even we, the audience, won’t know who to trust.

How Does the Cast Setup the Final Alice in Borderland Story?

The casting tells a clear story. This isn’t about random survival anymore. It’s a targeted rescue mission with a personal villain (Kento Kaku’s Ryuji) and established native threats (Banda and Yaba).
The return of Chishiya is particularly fascinating. Where does his loyalty lie? Will he help Arisu, or play his own game? And Ann’s return suggests the mysteries go deeper than mere physical challenges.
This blend of old and new creates a powerful dynamic. We care deeply about the returning characters, which raises the emotional stakes exponentially. Every game they’re forced into will be agony to watch. Meanwhile, the new actors inject fresh uncertainty and danger into a world we thought we knew.
