Jun is left looking at what remains of Shinku, and is left with deep regret at having ever chosen not to wind the key in the first place. His younger self who originally did choose to wind the key rushes to the tragic scene, carrying what Suigintou identifies as Shinku's doll case. Jun who didn't wind the key is now faced with the careful task of reassembling poor Shinku, so that she may return to a life with the Jun who wound the key, and so that he may gain the confidence to live his own life as well.

Souseiseki has come back to life thanks to Suiseiseki's donation of her own twin 'soul fragment,' her Rosa Mystic, but this renders Suiseiseki lifeless. Now Jun, Shinku, Suigintou, and the twins are trapped in an N-Field with Kirakisho. The 7th and most wicked doll without a body to call her own, is hiding and regenerating, watching Jun from the shadows, desperate for him to become her master.

Jun has been trussed up by Kirakisho's thorny branches and feels powerless to make up for his mistake in putting together a doll; a vessel for Kirakisho to use in order to get into his world "where the key was not wound." He realizes that the only way to redeem himself to his first doll, Shinku, which is to save her life by becoming her master and foodsource, but Suigintou, Suiseiseki, and Kirakisho stand in his way, knowing that whoever secures the contract with Jun will be the victor. Through Suiseiseki's slight of hand, Jun is flung into World No. Zero where his middle school younger self 'who wound the key' languishes with Kanaria, and a new, unexpected doll with miss-matching eye suddenly appears.

Middle school Jun 'who wound the key' still lies trapped in the N-Field with Kanaria where time passes slowly, while Shinku prepares for her final night with university Jun 'who did not wind the key' as the stage production of Practica Dolls begins. The empty clock strikes and Kirakisho magically appears in the vessel of Jun's "very own doll" he had been working on.
