Season 2

The ¥100 million experiment returns on a stage nearly 10 times larger than Season 1. Under all-new rules, Masuda (NEWS), Becky, and Hasegawa (Sissonne) recruit friends for a team battle testing strength, brains, courage, and friendship. Their first recruit is a controversial idol, followed by Olympians, singers, actresses, and top comedians. The first friendship battle begins!

The first battle is "King Dodgeball," a three-way battle of alliances, deception, and teamwork where a team loses once its King is hit or all its members are eliminated. Masuda (NEWS) recruits Olympians, Hasegawa (Sissonne) counts on athletic idols, and Becky fields top comedians. Will they trust their friends' abilities, or spend ¥8 million on a powerful game-changing item to secure victory?

The second battle is the ultimate mind game: "Chicken Card Battle." Teams score by drawing opponents' number cards, but the Chicken card drops the score to zero. Masuda's team fields Atsuhiro Sato and Rino Katase, Becky pairs Marika Matsumoto with Gekidan Hitori, while Hasegawa teams Tsuda (Diane) with legendary rapper Zeebra. Then Rino Sashihara arrives with a surprise comeback challenge!

Hasegawa (Sissonne) gets a lifeline when Rino Sashihara arrives for a special challenge, joined by Olympic gold medalist Shizuka Arakawa. Meanwhile, the teams race to recruit more celebrity friends, including Fuma Kikuchi, Toshiaki Karasawa, Yoshihiko Inohara, and Ano. Then the dreaded "Rat Card" returns as Hasegawa tries to lure a rival's teammate away with cash, throwing friendships into chaos.

The third battle, "Friend Elimination Quiz," is a ruthless buzzer quiz where every correct answer knocks an opponent out, and the last team standing wins. A quiz genius dominates, forcing others to rely on sheer numbers. Before the final showdown, the MCs unleash the sinister "Join Me Card," a betrayal twist that could change the game and every friendship before the ¥100 million finale!

The ¥100 million friendship battle reaches its finale as betrayals shatter alliances and tensions explode into open conflict. Lies and mind games push every team to the brink before the final battle: the "1000m Friendship Relay". Eleven teammates pass the baton to anchors Masuda (NEWS), Becky, and Hasegawa (Sissonne). After 14 hours and 142 friends, who will cross the finish line first?
