A giant mechanical beast Scout Berserker appeared.

Kaito transforms into Ultraman Max…

Within the transformation dimension, Max told Kaito that he would soon have to return to nebula M78. Kaito was affected by Max’s words. From now on, he could only rely on his human strength to protect the Earth…

Strange-looking figurines began appearing on the streets. Sometimes, the Automaton figurines would utter in unison,"The Time Has Come For Earth’s Judgement…”

The Automatons warned,"In 30 hours, if mankind does not cease its corrupting economic activities, ‘DELOS’ would destroy all of DASH bases.”

According to Proffessor Yoshinaga , ‘DELOS’ is a subterranean alien civilisation. Kaito and Mizuki headed to meet the Delosians to initiate negotiations. But while making their voyage to the centre of the Earth, they lost control over their vehicle and Mizuki sustained severe injuries.

As Kaito administered first aid to Mizuki, a small mechanical beast Berseker appeared from the Delos Subterranean City. Berserker explained that mankind’s pollution of the environment had damaged the ozone, letting in harmful radiation that threatens the survival of the Delosians. The mechanical creature added that once the defensive “Berserker System” has been activated, it couldn’t be stopped.

The surface dwellers would be annhilated.

Kaito has the burden of the surface dwellers’ survival and Mizuki’s life resting on his shoulders…
