Libra Festival

The Libra Festival (called the Scale Festival in the Crunchyroll subs) was an event that took place in Akihabara during the first October after the Catastrophe.

Trivia

 * Crunchyroll translates the name as Scale Festival, which loses the original name's reference to the astrological sign.
