Ep. 6: Sora and Shiro wager their tablet against Jibril's freedom in a materialization shiritori game.
Aired on May 14, 2014

Sora and Shiro challenge Jibril to a game of materialization shiritori, betting their tablet computer containing books against her freedom. During the match, they deduce that Disboard lacks scientific research by observing how the environment reacts to specific words. They exploit this weakness by removing Coulomb's law, which induces a hypernova and forces Jibril out of the game. Impressed by their strategic victory, Jibril solemnly pledges her loyalty to the siblings. This encounter highlights their ability to manipulate the game's mechanics through logical deduction and scientific understanding, securing their advantage against a powerful opponent.
