It's Summer! It's Camp! It's Vanguard! - S1.E34

Q4 has gone to the beach in order to train at Vanguard - though a lot of its supporters, such as Katsumi, seem to have other priorities. The team meets up with Team Caesar, who set up the training camp, and they quickly engage in cardfights. Surprising everyone, Kai actually defeats Kenji, and the two engage in an elaborate discussion about strategies and tactics. In the meantime, Aichi loses to Yuri five times in a row. Yuri requests to see Aichi's deck, and once she does acknowledges that it's a good deck, but with a weak unifying victory strategy. Aichi thinks about her words as everyone prepares curry for dinner, and while everyone else sleeps, he begins working on his deck.
