On this day, OTO-ONI NO Takeri (音鬼ノ哮) launches the long term live-limited distribution of a "short play collection" (短篇戯曲集) titled Tawamure Iroha (戯いろは). At each show, each attendee is permitted to choose one from of a number of releases that constitute the collection, each of which contain one short song. It is not known how many releases were made available at each live, and it is not perfectly clear when new releases were introduced through this means, but it is believed at least I-hen (い篇), Ro-hen (ろ篇), and Ha-hen (は篇) were among the available choices at the first few participating shows.

Given this atypical means of distribution and lack of comprehensive data, please note the release dates provided for each Tawamure Iroha (戯いろは) release should be viewed only as their first known instance of availability, and by no means should the list of releases provided here be considered complete or exhaustive.
