The Bizarre M78: From the Start, I Encountered the Light's Chainsaw Man

[Parallel Universe + Merged Universes + Fall of the Land of Light]

Two and a half years ago, a light-powered sawman who looked just like Ultraman Ace appeared and defeated Viaroga.

Everyone thought... it was a bioweapon modeled after Ultraman Ace. Only Koseki Ibuki knew that it was the real Ultraman Ace.

Two and a half years later, a strange video and a shocking conversation that only he could hear forced Koseki Ibuki to reveal the secret.

"That's Ultraman Ace, corrupted by strange light!"

Before long, more and more monsters invaded Blue Star, and even a mutated Taro appeared.

Everything seemed to point to M78, where an unknown mutation had taken place.

On this land steeped in despair, can the miracle called bonds save everyone once more?
