Summary
As the game begins, Kenji suggests that the group should all use the same card so that they end the game in a draw.

STARTING DEBTS: Kenji, Chigusa, Nomura, Uzaki, and Sakashita: 1 million yen

ROUND ONE:
Kenji suggests they all put "scissors," while he plans to use "rock" so that he will be the sole winner, passing on 500 thousand yen of his debt to the four losers so that he will only have 500 thousand yen of debt remaining.

After he does this, he expects his friends to be angry and plans to make up an excuse and suggest for the next round, they can all use "rock" and he will use "scissors," when in reality he plans to use "paper" and pass on the remaining 500 thousand yen of debt.

To his surprise, in round one, all four of his friends put "paper" while he puts "rock," and he is the sole loser of the round. He is now 3 million yen in debt, while his friends are all only 500 thousand yen in debt.

They explain that they were trying to intentionally lose to Kenji by putting "paper," and he must have chosen "rock" knowing he would lose.

DEBTS: Chigusa, Nomura, Uzaki, and Sakashita: 500 thousand yen. Kenji: 3 million yen.

ROUND TWO:
Nomura suggests that for round two, they will all use "rock" so Kenji can use "paper" and win by himself. He tells Manabu that if Kenji wins, the 2 million yen debt incurred in round one can be transferred back to them. Then, he plans to clear the last game by all choosing scissors, ending in a draw.

Kenji agrees, but later hesitates in placing "paper," thinking that his friends are betraying him and will put "scissors" to get rid of their remaining debt, causing him to lose and shoulder the 10 million yen debt by himself. He also worries that if he tries to counter with "scissors" and they don't betray him, using "rock," he will still lose by himself. He debates whether he should believe his friends, and concludes that they are his friends and would not betray him, deciding to use "paper."

While Kenji uses "paper," his friends betray him and use "scissors," causing him to lose round two as well. Since the game is not cleared, his debt doubles into a total of 10 million yen.

ENDING DEBTS: Chigusa, Nomura, Uzaki, and Sakashita: 0 yen. Kenji: 10 million yen.
