15 seconds of Gaiden OVA2

Clicking on the image below, you can see some scenes from Saiyuki Gaiden OVA2!!!
As I thought, some cutted parts of the two first volumes will be showed in the other OVAs.
We can see Goku on a cherry tree. Probably the scene is about the party under the cherry trees showed in vol.2.
Then...is showed the moment in which Konzen catches Goku who is falling down....
