I'm going to choose to believe that Koji Masanari is a broken-hearted shell of a director just going through the motions after Welcome to the Space Show flopped as badly as it did, particularly given how much effort and attention to detail was poured into that movie.
But, hey, this is rarely an industry which actually rewards effort.
He should have learned from Iso and just fucking retired himself if he didn't feel like contributing anymore. No show > fucking garbage show.
