Banri Watanuki, a former resident of the complex, has returned from training with Zange Natsume, his Secret Service agent. Soushi has known Watanuki and Natsume since childhood, which makes this seem awkward to Ririchiyo. The four participate in a walk rally to obtain signatures from all the residents. After Ririchiyo and Soushi finds Karuta, Natsume reveals that Watanuki had originally gone off to train in order to protect the girl he loves. Ririchiyo seems deep in thought after she begins to have an irregular heartbeat. (Source: Wikipedia)
