8th episode of spinoff anime to be included in 4th BD volume on April 22

Bandai Visual began streaming the seventh episode of the Comet Lucifer television anime's spinoff SD Flash anime "Garden Indigo no Shasō Kara" (From Garden Indigo's Window) on Sunday. The episode features the characters Sōgo Amagi, Moura, and Felia discussing the government of Gift. Moura quizzes Sōgo and Felia about how leaders are chosen in Gift, giving them four choices: 1. citizen election every four years, 2. chosen by a central government, 3. lottery, and 4. inheritance. Sōgo guesses wrong: the correct answers are 2 and 3. Moura elaborates that while nominally the central government sends administrators to govern the Gardens, there are some who have made it a hereditary position, such as the Valoffs. Zoneboyle governs all of Gift as an executive official of the central government, but an advisory council of elders exist to check his power.

This episode will be a bonus extra on the fourth Comet Lucifer Blu-ray Disc volume along with a Blu-ray exclusive episode 8 on April 22. Episode 1 will be available along with the Blu-ray-exclusive episode 2 in the anime's first Blu-ray Disc volume on January 29. Episode 3 will be available with the Blu-ray exclusive episode 4 in the second volume on February 24. Episode 5 will be available with the Blu-ray exclusive episode 6 in the third volume on March 24. Bandai Visual streamed the SD short's first and third episodes in October, and streamed the fifth episode earlier this month.

The main TV anime series premiered in Japan on Tokyo MX on October 4. Sentai Filmworks has licensed the series, and Crunchyroll is streaming the series as it airs.

The story takes place on the planet Gift, where precious crystals called Giftjium are buried in the earth. A young man named Sōgo lives in Garden Indigo, a prosperous mining town. Sōgo's hobby is to collect rare crystals. One day, he gets wrapped up in a riot caused by his classmates Kaon, Roman, and Otto, and he loses his way until he finds a lake deep under the ground's mining ruins. There, he meets a mysterious girl with blue hair and red eyes that gaze straight ahead. The story follows the adventure of what happens after this meeting.
