New Kamen Rider Calibur's true identity is Kento Fukamiya who was believed to be dead. Kento tells them that he will seal all the Seikens in order to save the world from destruction.
"I am the only one who can protect the world"
With these words, he disappears.
Why was Kento able to revive? Mei Sudo & Ryo Ogami (Kamen Rider Buster) are confused about his revival. And what does he mean by sealing the Seikens?
Touma Kamiyama (Kamen Rider Saber) & others believe that they'll get to fight along with Kento once again & hence they now decide to focus on Kamen Rider Saber Primitive Dragon who had gone berserk for the third time.
On the other hand, Ren Akamichi (Kamen Rider Kenzan) is happy to know that Kento has revived. But Reika Shindai (Kamen Rider Sabela) tells him that Kento is an enemy.
Just what had happened to Kento?
Meanwhile Yuri (Kamen Rider Saikou) who is the first owner of Ankoku-Ken Kurayami talks about the fight to attain 'the Book'. He also talks about the hidden power of Ankoku-Ken Kurayami.
Yuri decides to meet Kento alone. But that leads to a battle.
Kento Vs Touma!
Calibur Vs Saber Primitive Dragon!
Kamen Rider Sabela also appears there and Tetsuo Daishinji transforms into Kamen Rider Slash to stop her. Ryo Ogami also transforms into Kamen Rider Buster to stop Kento.
