This is the Japanese version which has never been released, leaked online on July 3, 2014.

The story centers on a child named Mark (originally known as Hiroshi (ひろし) in the unreleased Japanese prototype) who, on his way home from a baseball game, is approached by a winged, griffin-like alien named Bert (originally known as Value (バリュー) in the unreleased Japanese prototype) who seeks assistance in ridding "evil monsters" from his realm, "Dark World". Being the first person he encounters, Bert tries to enlist Mark as his aid in battle. Mark is reluctant to help, but Bert explains that anyone will do, and that Mark's baseball bat will be as good a weapon as any. Bert quickly whisks him away, and on the way to Dark World magically fuses himself to Mark so that they are one being (with Mark able to transform into Bert for a limited time).
