Privileged but depressed, Emi Kaido witnesses her life change in an interdimensional flash when a band of otherworldly heroes rescues her from an ambush of killer robots in central Shibuya, Tokyo. Soon the chaos unfolds all around the so-called Case.
As news of the Shibuya incident sparks a media frenzy, Emi reluctantly uses her luxury abode to protect her motley crew of warrior heroes. But a buoyant mood turns tense when interdimensional traveler, Joji, tells of the dreaded Z.
Having learned Damian's true identity, Takeshi transforms into Polimar to thwart his formerly cordial ex-client's grotesque alter ego. Can Polimar keep up? Or will a grand display overwhelm the team and the ward of Shibuya?
It's Halloween, and Emi has been dragged to a party as the team chaperons. Yet as soon as the party starts, Emi is off, compelling Joji to follow suit. Instead of finding Emi, Joji runs into the dangerously seductive Bell Lynn, who wants one thing.
Calmed by her father's words, Emi has returned to a normal life as a teenager. Takeshi and Tetsuya, however, aren't convinced as they see a more dangerous reality surrounding her.
Emi and Kaan are pulled into an alternate dimension, only to find Ken and the others embroiled in a deadly brawl against a super-charged Bell Lynn. The barrage of weaponry that follows brings an end for some and a new beginning for others.
