ตอนที่ 3: เอมีติดตามไอจิไปยังคาร์ดคาพิทัลและค้นพบความหลงใหลในวอร์เดีย

Aichi's little sister, Emi, is worried by Aichi's different behavior as of late. After school, Emi sees Aichi with Morikawa and Izaki, who want him to go with them to Card Capital. However, Emi misinterprets the situation as Aichi hanging with the wrong crowd. Concerned for her brother, she secretly follows the trio to Card Capital. There, Emi is astounded by all the people in the shop, including Aichi, Morikawa, and Izaki, playing Vanguard. It is then that the card shop's manager, Shin Nitta, appears and introduces Emi to the world of trading card games. The two then observe a cardfight between Aichi and Morikawa. The battle ends with Aichi winning without taking any damage. Watching Aichi play, Emi sees how much her big brother has changed because of Vanguard. And so, she becomes supportive of Aichi playing the game. (Source: Wikipedia)
