Normally, guests—even VIP members—aren't enough to invite the young lady of the dojo to appear personally.
Yagyu Junko appeared here for only one reason; she overheard the conversation among the three people.
But she didn't rush to show herself. First, she couldn't figure out where these young people came from, and second, she wanted to observe more and see their nature.
The Liusheng Dojo uses a recommended membership system. Virtually all guests need to register their identity information, with only a very few anonymous membership cards given as gifts to special guests whose identities are inconvenient to reveal.
Yet Yan Yu'an suddenly took out three cards, confusing Yagyu Junko.
The three cards came from three different places, and the owners of those cards could no longer be contacted.
Wang Yunxiao and the others are famous within certain circles but little known outside those circles.
