Kagaku Ninja-tai Gatchaman EP28 - The Invisible Demons

Children keep dissolving into thin air. Even the members of the Science Ninja Team become eye witnesses to one of the disappearances. Ken follows some tire tracks on the ground and enters a mirror maze. There he discovers some snail mechas, but they become transparent and disappear.

Galactor is collecting children with strong brain waves in order to produce the brain wave monster Alphagila. The monster reads the secrets of the ISO in its institutions, and then destroys them. Nambu enhances Jun's brain waves for a while and makes her pose as a bait. The Science Ninja Team locates her radio signal, sneaks into the base beneath the mirror maze and saves the children.

Then, based on the information he got, Katse is going to an uranium storage room in the desert.

But, because the interior of the room becomes a mirror dome, the mechas which snuck in and should be transparent, become visible. In reality, they fell into the trap Nambu prepared. The mechas are thrown aside by the fast-approaching God Phoenix.

The Science Ninja Team thinks that they have cornered Katse for sure this time, but he gets away again, disappearing in blue-white flames.
