Hiroto starts his investigation by having the CEO interview Dr. Asama, the co-author of Shuichiro Korogi's thesis. Meanwhile, Youta is watching Kako Tengan, a famous lawyer, being interviewed on TV. Later, Hina wins the mahjong preliminaries online under Youta's name. She reveals she did this in order to ensure that Youta meets Kako in person at a mahjong tournament she is organizing. Two days later, Youta heads out to compete in the Libertas Cup while Hina, Kyouko, and Ashura cheer him on. In the waiting room, Youta meets Kako. Once the match begins, Youta follows Hina's instructions, which initially has him in last place. However, as the match continues, he starts to make a comeback when he uses unconventional methods, which impresses Kako. As such, Youta ultimately wins the Libertas Cup. After the match, Kako attempts to seduce Youta. However, he turns her down, much to her chagrin. When he tells Hina what happened, she is annoyed at the missed opportunity. (Source: Wikipedia)
