May These Memories Disappear. The traditional nuclear family has demonstrated itself throughout human history that it is the fundamental building block of society; while this dynamic has a record of being constructive, the consequences for the obverse have far-reaching devastation as a girl named Wakaba has demonstrated when her parents constantly lash out at each other with such ferocity that Wakaba wishes to no longer exist as she begins her school commute. Meanwhile Touko and Rinko are using their home commute to exchange perspectives of their previous job when they come across a boy named Kentaro using a rather dubious method to discern Wakaba's status; after a »Whoa, hold your horses!!!« intercession and some teasing from Rinko, what Kentaro and the two Yume Tsukai find is no laughing matter -- Wakaba enveloped inside an egg that is reversing the effects of Wakaba's actions during her lifetime. Desperate for Wakaba's survival, Kentaro races off to find Wakaba's parents with Rinko right on his heels in a bid to intercept the nightmare and prevent its rampage through time all the way to Wakaba's first day of grade school only to be one step behind the whole time. Rinko's observation that Kentaro himself has some memories of Wakaba along with Touko having figured out the mechanics of the whole situation which has come to a head becomes the ultimate skeleton key by which the nightmare is neutralized; as an ancillary bonus, Wakaba successfully attains her first kiss while her family government works things out in a rational and mature fashion.
