Rad Action / NinjaKun Ashura no Shou is an arcade game representing a merging of two titles.  'Rad Action' might refer to a Western release title, whereas 'NinjaKun Ashura no Shou' is likely the original Japanese title.  This suggests the game possibly features a ninja protagonist involved in fast-paced action.  Gameplay probably involves platforming, combat, and a storyline related to the ninja world.   Determining the original developer and the specific regional releases requires more investigation.
