Having slept on the roof of Jun's apartment complex rather than inside her case, Suigintou's energy has been severely drained, and Shinku allows Suigintou to sleep inside her case during the day. At work, Jun buys a book titles A Doll in the Palm of my Hand for Shinku and finds another volume from the second series. Upon returning home, Jun receives another volume and hides them from Shinku. Jun and Shinku read the book he bought together. At night with Shinku asleep, Suigintou sees Jun assembling the doll, and agrees to keep it a secret from Shinku. In exchange, Jun offers himself as a medium for Suigintou. Meanwhile inside the n-field, young Jun, knowing nothing about the second series, deduces that that someone had been sending the adult Jun the message to construct the doll as himself. Young Jun tries to send a message to warn adult Jun not to assemble the doll, but the message is blocked by Kirakishou.
