DC Super Heroes vs Taka no Tsumedan

The Joker arrives in Japan to steal the Eagle Talon Society's secret weapons, drawing the Justice League after him. Something is wrong with Batman, however, and the Society concludes that the answer lies in the night Bruce Wayne lost his parents.

Traveling into Batman's past, the least qualified rescuers imaginable attempt to repair his wounded resolve while the Joker advances his plan. Their struggle becomes even harder as their resources disappear, their surroundings lose detail, and they risk being reduced to little more than stick figures before the final confrontation.
