Tetsu Appears Cardfight!! Vanguard : Season 2 Episode 13

While Team Q4 trains at Card Shop Handsome to get ready for the next round of the VF Circuit, the group is informed that Tetsu has arrived to Card Capital, assuming that he is causing trouble. However, their assumptions are disproven when they return and see Tetsu helping out Emi and the other kids at the shop. Kamui asks Tetsu what his real intention for coming is, to which Tetsu answers by telling Q4 how weak the team is due to losing at the VF Circuit's Singapore Stage. Enraged, Kamui challenges Tetsu to prove him wrong. Tetsu accepts the challenge, and the two start their cardfight. With support from the latest expansion set, Tetsu uses new Dark Irregulars to soulcharge, and then he utilizes the Limit Break of Dark Lord of Abyss to overwhelm and defeat Kamui once again. Tetsu leaves, warning Q4 of stronger teams awaiting them in the VF Circuit.
