The Woman By Her Side Episode 9

Election Committee Chair, Yuna Yomotsuki gives an update on the election, naming the top 10 contenders, with Kirari Momobami still in front with a long lead, Terano Totobami in second place and Yumeko Jabami in sixth place. Yumeko suddenly challenges Kirari to a gamble, but Kirari's fiercely loyal secretary, Sayaka Igarashi, violently objects, and challenges Yumeko to a gamble for their lives. However, Yumeko changes the bet - they agree that Sayaka will bet her friendship with Kirari against Yumeko's promise to never gamble again. Kirari proposes the game of Tower of Doors and as an added incentive, Kirari proposes that the loser jumps from the 5th floor, also forfeiting their life. Sayaka and Yumeko agree. The game begins and Yumeko opens a door which leads nowhere. Then Sayaka opens a trapdoor and descends 1 floor, but defying logic, Yumeko then opens a door in the external wall.
