Will there be a second season of Grand Blue?

As of September 7, 2022, Zero-G or any related company has yet to renew the series for a second season. Grand Blue’s first season aired between July 14, 2018 – September 29, 2018. Over the past two years, there has not been a second-season confirmation from official channels. It is a common situation for many anime and no need to yet worries since there is no cancellation. If an anime has enough popularity, enough source material, and enough financially profitable, it often gets a new season approval.

Since there is no official statement on this issue, we speculated about the second season by evaluating these main factors. The decision committees of the anime also bring these metrics together and give approval for new seasons. Therefore, when you reach the end of the article, you will reach conclusions about whether the Grand Blue anime will get a new season.

Manga status of Grand Blue

As we mentioned before, the Grand Blue anime series is a manga adaptation and uses written work as source material. The manga, written by Kenji Inoue and illustrated by Kimitake Yoshioka, is published by Kodansha in the magazine “Good! Afternoon” since 2014. The good news is that the manga series is still being written. With the last volume released on March 07, 2022, the manga reached 19 volumes. The 19th volume has been published on August 05, 2022. Besides, the manga series is published in English by Kodansha USA.

The first season of the anime consisted of 12 episodes in total and only 5 volumes were adapted into the anime. There are 13 manga volumes left for the new anime seasons. The conclusion we can draw here is that there is more stock material for at least two seasons. Also, considering that the manga series continues, there will be more source material in the future. The continuation of the manga series is another detail that increases the possibilities of the new season. Because the advertising work of the ongoing series continues at full speed, and a new anime season radically increases manga sales.

Disc sales (BluRay and DVD) of the anime

Disc sales are very important for anime. For an anime to have a new season, it is expected to sell at least 4,000 discs on average. If it remains below this number, the second season may not be seen as profitable by the decision committee. However, due to the increasing popularity of online streaming services in recent years and the shift in watching habits in this direction, it isn’t easy to reach these sales numbers, even for the most popular anime. However, although disc sales have fallen in recent years, it was still popular in 2018 when the anime went on disc sales.

The disc sales for Grand Blue did not go very well, it sold only 1,699 units, and that number is far from the target. When evaluated in terms of disc sales, a new season is quite unlikely. Overlord season 3, which sold 7,222 units, and Banana Fish, which sold 7,944 units, were the other anime that went on sale during the same period.

Popularity and other factors

Grand Blue, which gained new viewers every day even over the years after its first release, ranked 252nd on the Myanimelist’s popularity ranking. The anime has a Twitter page followed by 45k people. Although it is not a successful social media popularity in Japan, still there is a strong Google search volume about anime. Generally, we can say that 70% of animes with over 100k followers have been approved for a new season at least once. However, this rate drops to 40% for around 40k followers. Of course, this is not just a metric on its own, and the worldwide popularity of Grand Blue is better than its popularity in Japan.

Animes with similar follower number

Considering the current popularity, a second season can be successful in viewerships. Creators may evaluate the current popularity and take action for a second season. In addition, the fact that a worldwide popular platform such as Amazon Prime has acquired the broadcasting rights makes the possibility of the second season high. Finally, the release of a live-action movie is a positive factor in keeping this brand on the agenda. Everything looks great except the disc sales and the overall popularity in Japan.


When is the release date of the second season?

There is no second season renewal yet, but we see the possibility of a second season pretty high as a result of the above evaluation. Although the disc sales are not going well, the current popularity is quite high, and there are enough manga chapters for the second season thanks to the ongoing manga series. If we get a confirmation, a new season may air around 2023 or 2024, considering the average production time. If you don’t want to wait for a new season and are impatient for continuing the story, you can read the manga series from the beginning of volume 6. We can also recommend you to watch Miss Kobayashi’s Dragon Maid in the comedy and slice-of-life genre like Grand Blue till the anime have a second season.
