How about a Psychic powers season? Bad guys want to force everyone into a hive mind state, while the Rider fights for individualism. There's a hunt for items that late either the kaijin or the rider see into the future as well as expand one's mental powers.

Victims of the week can be influential people that the kaijin want to eliminate/corrupt, as they're at a part in their life where they decide what their future will be.

The rider could have had an original idea/dream stolen from them by a rival, who now works with the kaijin with the agreement that parts of his personality will be dominant in influencing the hive-mind once constructed.
