This Movie also takes the same time frame as the Bount arc, but there are no Bount and the other Mod Souls.
In the Bount Arc, Ichigo wasn't able to do his bankai until the end of the Bount Arc in the Human World. But in this movie he was easily able to go bankai.
The second OAV also takes during the same time pace as the Bount arc and Movie. The time frame, isn't as ruined or mixed up. Still a goof having all three at the same time.
