Episode Title:
Refrain - My Mission.
Episode Description:
Vivy confronts the Archive about its motives and it reveals that it intends for AIs to replace humans, as it finds the latter have pushed their burdens onto the former. However, it also states its amazement at Vivy's ability to write a song and makes a bet with her: if Vivy "sings from her heart", it will halt its actions. Toak launches an attack on Arayashiki Tower, where the Archive's server is located, so Matsumoto can shut it down using the same virus Yugo used on Diva, which he deduces came from the Archive. However, they end up falling into a trap, resulting in everyone except Vivy and Matsumoto being killed...
