** [[spoiler:Nodoka's charred tablet retains a small portion of the Yorumun ''tsukumogami''. Though much more childlike than the original one that ascends, she is [[AnimateInaimateObject just as sentient,]] and able to use weaker forms of the original's sea-based illusions.]]

In her youth, Sumireko Ogawa aspired to become a successful writer, promising herself that she would write a novel she can be proud of.

Several years later, the 27-year-old Sumireko is working as a bookstore clerk, struggling with writer's block and grappling with the fact that her youth is now behind her... until, on the eve of her 28th birthday, Sumireko finds herself becoming a little girl under the moonlight, and rejoicing at the possibility of finally writing her novel again.

Unfortunately, this "blessing" quickly becomes a nightmare: Sumireko is slowly dying from the side-effects of being restored to her younger self, and she is only saved by the intervention of her unassuming co-worker Ren Adashino, a self-professed dabbler in the occult. Sumireko's own interest in the occult and desire to find inspiration for her upcoming novel leads her to team up with Ren and his equally-creepy sister Oto in solving the many supernatural mysteries around her...

* ShapeshifterBaggage: Turns out that just because Sumireko can turn back into a child due to her curse doesn't mean the extra biomass from when she was an adult magically goes away; it's all compressed to the point that she will start bleeding from the ears and eyes if she stays a child for too long. [[spoiler:This detriment goes away when the "Tsukuyomi's Water of Life" curse transfers to Sumireko thanks to her high compatibility to it; now that she is the 'curse' herself, she can safely shift between ages with no ill effect.]]
* VirginPower: Sumireko's curse "Tsukoyomi's Water of Life" literally requires the enchanter to be a 28 year old virgin.
