The alien creature extends its power to four other neighboring castles, giving the daimyō lords each an evil sphere of power. The lords are taken over by the alien's evil power, and use the spheres to summon ninja armies and monsters to attack villagers.
The extraterrestrial being expands its influence to four adjacent strongholds, bestowing each daimyō lord with a malevolent orb of authority. The lords are subsequently enthralled by the alien's malignant energy and utilize the orbs to mobilize ninja legions and beasts to assault rural populations.
