Chapter 16: Saving the World, A Ray of Light.

is the sixteenth episode of Kamen Rider Saber. It features Yuri's transformation into Kamen Rider Saikou.
==Synopsis==
Touma has defeated Calibur and saved the world with his friends. However, Daichi left a new mystery moments before his death. The end of the world has already begun, not to mention that Luna is a special being who connects both of their worlds, and a true enemy within the Sword of Logos was involved in the incident 15 years ago. Unlike Daichi, Touma vows to reveal the truth with his friends. However, the Southern Base messenger, Reika Shindai, was operating from behind the scenes. Just then, the other swordsmen appear in front of Touma telling him "Give us your Seiken and Wonder Ride Book." Touma is confused because it was just yesterday when he fought alongside them as allies. Just then, a man wearing a hood appears. "I'm the sword who protects the world!" It was in that moment, when this man suddenly transforms.
