The Chips Are Down

S2, E9: Yumi and her family are going to move away. Her father, Mr. Ishiyama, has been laid-off work and they cannot afford to stay in their current home while he tries to find another job. Devastated by the idea of Yumi leaving, Ulrich gets an idea: he plans to secretly use the "return to the past" program to buy a winning lottery ticket which he will give to Yumi’s parents. He carries out his plan and, to no one’s surprise, wins the lottery draw. But his friends realize what he has done.
