Kamen Rider Saber S01 E40 Chapter 40: The Shining Friendship of Three Swordsmen

"Become a writer and a swordsman!!"

Using Omni Force's ability to control Wonder Ride Books, Isaac takes control of Ryoga via his book and forces him to attack Reika. Isaac then targets Luna once more due to her connecting Earth to Wonder World despite Tassel's best efforts to protect her. Touma, Rintaro, and Kento unite to protect Luna and defeat Isaac for good. However, Storius takes advantage of the situation to personally kill the former Master Logos and steal the Omni Force Wonder Ride Book for himself.
