Dog Trainer.Using the special bracelets awarded to them for winning the tournament, TRY3 infiltrates the United Sanctuary branch. However, a security guard mistakes them as native fighters and separates the trio. Tokoha is horrified by the harsh training programs of the branch and decides to confront Rin about it. Elsewhere, Shion is taken to a GIRS arena where he is challenged to a cardfight by that guard who is in fact Yuya as Shion had suspected. While battling against Yuya's new Shadow Paladin deck, Shion is forced to wear the bracelet which delivers physical pain to him whenever he takes damage. When Shouma appears to spectate the match, Yuya reveals how it was Shouma who invited him to the branch. Yuya eventually rose up the ranks and gained the position of Dog Trainer, a security personnel/disciplinary teacher who punishes losers and enforces the branch's mottoes of "winning is everything" and "weakness is a sin" to others. Offended and outraged upon hearing of the branch's morals, Shion swiftly defeats Yuya and then confronts Shouma. Meanwhile, Chrono meets with Taiyou again and tries to convince him that his current mentality of wanting to become strong is not right. As Chrono attempts to flee from the facility with Taiyou, Kouji stands before him.
