Tập 2: Riki và Saya tích trữ đồ dùng trước khi đối đầu với các Giám đốc của Bóng Tối trong hầm ngục

2

After venturing into three basements of the underground dungeon full of booby traps, Riki and Saya decide that they must first stock up on water, food and supplies for the expedition. On the next day, Riki meets up with Saya at the shopping district after school. While shopping around, Saya is excited when playing a claw crane, which sparks Riki's interest. They return to the mission back in the underground dungeon on the fourth basement, where Riki has the feeling that he has met Saya sometime in the past. While trying to find a downward staircase, Riki and Saya are soon attacked by the Darkness Executives. After Riki activates the downward staircase and covers for Saya, they manage to escape into a room, which contains a hot bath. Saya awkwardly undresses and gets into the bath to relax, much to Riki's anxiety. After she gets dressed again, they decide to have a picnic together. Riki suddenly realizes deep in his heart that he fell in love with Saya some time ago. (Source: Wikipedia)
