==Synopsis==
JTC makes Chris an offer to join Xaviax, but Chris refuses. Danny and Albert start a fight in the bookstore, and an all-out battle begins between Dragon Knight, Wing Knight, Sting, Axe, and Spear. When Strike joins in on the fight, the result is devastating.
==Plot==
While Chris is writing in his journal, JTC appears and offers him a cure for his asthma if he betrays Wing Knight. Chris refuses and the two fight for the third time. Sting nearly gets vented but he manages to escape on his Advent Beast. Kit arrives at the bookstore and tells everyone about his fathers abduction when The Cho Brothers show up looking for a fight. Kit, Len, Chris and Danny enter Ventara while Albert transforms in the bookstore proving to Trent and Lacey that the Kamen Riders exist. Kit takes on Axe while Chris and Len take on Spear, his Advent Beasts and mirror monsters. Kit has a chance to vent Axe but doesn't. Strike arrives and tries to vent Len but Chris takes the hit and is vented instead.
