Years had passed since Shin Hayata last fused with Ultraman, and he now discovered a fresh danger looming over the planet. Meanwhile, his son, Shinjiro, began exhibiting signs of extraordinary power within himself.

Donning the protosuit, Shin sustains critical injuries while shielding Shinjiro from Bemular’s assault. In a moment of desperation, Shinjiro turns back to save his father.
