Kamen Rider Calibur had stolen the Ridebooks of Kamen Rider Blades (Rintaro Shindo) & Kamen Rider Espada (Kento Fukamiya). Kamen Rider Saber (Touma Kamiyama) were in trouble now. But Sword of Logos' Swordsmith Tetsuo Daishinji arrives and transforms into Kamen Rider Slash.
Kamen Rider Calibur escapes from the battle, but the Ridebooks are still stolen. But Storius and Kamen Rider Calibur still don't have enough Ridebook to surpass the power of King of Arthur.
Kamen Rider Calibur goes in the hunt of more Ridebooks of swordsmen.
Meanwhile Touma remembers Kamen Rider Calibur saying "Whatever you are seeing isn't meant to be true". He starts to think the real meaning behind it. Even Sophia is suspicious whether Kamen Rider Calibur's identity is really Kento's father Hayato Fukamiya.
Kento gets reminded of his thoughts for his father and he falls in a deep thought once again. Touma and Rintaro notice this. But Kento decides to keep distance from the two after thinking about what his father has done 15 years back.
He thinks why is his father even targeting Touma.
Messenger from Southern Base → Reika Shindai from gets in touch with Kento. Kento asks her "Do you want anything from me?". She gives him the Tri-Cerberus Wonder Ridebook which will make him achieve his Wonder Combo → Kamen Rider Espada Golden Alangina.

The three swordsman join swords together and make their decision to fight against Kamen Rider Calibur.
