5x9 - Cardfight!! Vanguard

Since Tokoha was young, she has admired a girl called Akane whom Tokoha treated like a real elder sister. Akane is a competent staff working in Dragon Empire Periphery. Akane feels lonely because both Tokoha and her are so busy that they have fewer chances to chat relaxedly like before. On the other side, Tokoha feels surprised for the content of Akane's quest.
