The Mass of a Chosen Future - S2.E4

Tomo and the others are apparently saved by Tomo's brother, Naotaka and then taken in by Kagakagari and Kristina. Kagakagari reveals that the ruins are the remnants of an Asura Machina testing ground and that they may contain a way to free Burial Dolls like Kotori and Misao. However, before they can retrieve the device Kyomu arrives and tries to use Ania as a hostage.
