Alt title: Seven took Zero's place in this battle?
Reibatos is on the run to achieve his goal.
I'm no fan of any Showa Ultraman series but I've heard some theme songs a bit. When these four Ultramen arrives at Yomi, cue the instrumental theme songs and I love it... (a bit)
Spoiler
Next week, Orb alone against Reibatos in the asteroid field.
