Ace of Diamond Season 4: Release Date, Renewal Status, Cast, Spoiler & Everything We Know

Ace of Diamond Season 4: Ace of Diamond is a popular sports anime series that follows the journey of Eijun Sawamura, a talented baseball pitcher who joins the prestigious Seidou High School to pursue his dream of becoming the ace of the team. The series is based on the manga of the same name by Yuji Terajima, which has been serialized in Weekly Shonen Magazine since 2006. The anime adaptation is produced by Production I.G and Madhouse and has aired three seasons so far, with a total of 201 episodes.
The third season of Ace of Diamond, titled Ace of Diamond: Act II, concluded in March 2020, leaving fans eagerly waiting for the next installment of the series. The season ended with Seidou High School advancing to the fifth round of the spring Koshien tournament, the most prestigious national high school baseball championship in Japan. The season also featured the growth and development of Sawamura and his teammates, as well as their rivalry and friendship with other schools.
So, what can we expect from the fourth season of Ace of Diamonds? When will it be released? Who will be in the cast? What spoilers are there? And what is the rating from IMDb? Here is everything we know so far about Ace of Diamond Season 4, as of November 28, 2023.
Ace of Diamond Season 4 Release Date
As of now, there is no official announcement regarding the renewal or cancellation of Ace of Diamond Season 4. However, there are some reasons to be optimistic about the possibility of a fourth season. First of all, the manga series is still ongoing, with 24 volumes published as of November 2023. This means that there is enough source material for the anime to continue the story. Secondly, the anime series has been well-received by both critics and fans, with an average rating of 8.1 out of 10 on IMDb.
The series has also won several awards, such as the Kodansha Manga Award and the Shogakukan Manga Award, for its popularity and quality. Thirdly, the anime series has a loyal fan base, both in Japan and overseas, who are eagerly waiting for the next season. The series has also been licensed and streamed by various platforms, such as Crunchyroll and Netflix, which indicates its commercial success and demand.
Based on these factors, we can assume that the production companies have a strong incentive to produce a fourth season of Ace of Diamonds. However, given the current situation of the COVID-19 pandemic, which has affected the anime industry in various ways, such as delaying the production and release of many anime projects, we cannot expect a fourth season to be announced or released anytime soon.
Renewal Status
As mentioned above, there is no official confirmation or denial of the renewal status of Ace of Diamond Season 4. However, we can look at some clues and hints that may indicate the likelihood of a fourth season. One of the clues is the ending of the third season, which did not conclude the story of the manga, but rather left it on a cliffhanger, with Seidou High School facing off against Ichidai Third High School in the fifth round of the spring Koshien tournament.
This suggests that the anime creators intended to continue the story in a fourth season, rather than wrapping it up in the third season. Another clue is the popularity and demand of the series, which may motivate the production companies to renew the series for another season. Moreover, the manga author, Yuji Terajima, has expressed his gratitude and support for the anime adaptation and has hinted that he would like to see the anime continue until the end of the manga.
Therefore, we can hope that the production companies will listen to the fans and the author, and renew the series for a fourth season.
