Cardfight!! Vanguard - Season 7 Episode 4

Chrono and Taiyou seek Kanzaki, who is training in a secluded mountain range. They tell him about the situation with Ryuzu, and in exchange, Kanzaki tells them more about Depend Cards; they are contracts between a fighter and a summoned unit from Cray, but summoning units require a large amount of Stride Force. Kanzaki also reminds Chrono of their fight when Chrono had truly summoned Chronojet Dragon, which surprises Chrono of his own untapped power. Meanwhile, Shouma approaches Ibuki and warns him of certain punishment. After spending the night at Kanzaki's hut, Chrono and Taiyou return to the city and confront Hiroki, following Kanzaki's hunches. Having rebuilt his deck, Taiyou challenges Hiroki to a rematch.
