Super GUTS immediately springs into action, taking on the monster that transformed from the Sphere and struggles through a tough battle. During this time, Asuka is surrounded by a dazzling light and a new giant of light appears!

The battle between Ultraman Dyna and the monster on Mars ends with Dyna's victory. However, Asuka is having trouble with the unknown power he suddenly received. Meanwhile, the mysterious sphere attacks the space station. Super GUTS springs into action, but the monster that transformed from the sphere appears on Earth as well!

Asuka is overconfident in his abilities and he ignores orders by attacking a small monster which came from a meteor that fell on Earth. It looked like the attack on the monster was effective, but another monster interrupts by emerging from the ground. The small monster that survived Asuka's attack was part of another monster!

Strange earthquakes are detected in the area around the Geofront factory where an underground city is under construction. Super GUTS confirms that there is a living creature moving underground. Factory machines are stopped to investigate this. The president of the construction company cares only about profit and gets angry and recklessly resumes construction...

The major league baseball player Himuro, who is a friend of Asuka, returned to Japan. They haven't seen each other in a while and Himuro says he hasn't been able to take the mound due to an accident during a game and is thinking about retiring. As Asuka tries to get him back on his feet, a powerful monster that can fight off enemy attacks with quick movements appears!

A giant mushroom shaped monster suddenly appears from the ground through its own will and declares it will erase mankind. A bacterial thread makes its way all the way through the computer network and Super GUTS cannot prepare to intercept the attack the way they want to.
