This decision was made by the developer under the consideration of improving the quality of content in the game.
The anime is currently still in production, and aside from this information, there are no further details regarding the anime project at the time.
After roughly 15 years without any new series, the anime is confirmed to return with a brand-new original story under the title “Bikkuri-Men”.
The staff did not mention the reasons regarding this decision. The announcement was closed with a wish that the players will play the newer game of the series.
Both of the trailers give glimpses of scenes and moments from the second cour of season 2 which is filled with actions and war.
This manga is authored by the same mangaka who also created the manga adaptation of the first season, Mizuki Sakakibara.
