The official website for the anime “Shine Post” announced that the seventh episode (as well as subsequent episodes) has been postponed due to the rapid increase in COVID-19 at Studio KAI.
The NTV will broadcast a special recap episode of the anime on August 23rd, instead of the seventh episode.
Episodes 7, 8, and 9 will now air on August 30, September 6, and September 13, respectively. The anime staff lists unspecified plans for September 20 and 27, but episodes 10, 11, and 12 will air on October 4, 11, and 18, respectively.
