Just when Asai determines Mari is the result of her mother’s ability to create a clone of her never-born daughter, an agent of the “Bureau” (or “Kanrikyoku”), Tsushima, arrives to take her away.
The father left town, and now the mother will do the same, leaving the virtual Mari a virtual orphan. That doesn’t sit right with Asai, so he has Haruki reset, and the formulation of a plan commences.
It’s actually pretty impressive how quickly and efficiently Asai directs the service he and Haruki are likely going to be providing throughout the run of the show: “erasing tears” by resetting and fixing the cause of those tears.
Their classmates assist with their own abilities, but when the one who allows Asai to share his memories with Haruki bristles at the prospect of defying the Bureau, Asai cuts himself with a broken ramune bottle until Tsushima gives permission.
Everything works out perfectly: Asai, with the help of the rest of the group, is able to show Mari’s mother the error of her ways; to stay and continue raising the girl who may not technically be her real daughter, but loves her nonetheless.
With Haruki and his classmates’ combined powers, Asai has gained the power to “erase sadness.” In the process, he’s also managed to awaken some feelings in Haruki, though the road is long.
He discusses this in great detail with Souma Sumire, who is a tough nut to crack: you get the feeling she’s glad Asai may have found his calling, but a part of her also regrets bringing him and Haruki closer together.
Mind you, the relationship between Asai and Haruki doesn’t become a romance overnight. After all, Haruki has only gained back a small portion of the full spectrum of emotions most humans carry and experience. She cuts her hair at his suggestion, but also confuses trust with love. Asai proves it when they kiss and there’s no spark.
Then he undoes the premature kiss by asking her to reset. After seeing what they managed to accomplish with Mari and her mother, Haruki believes following Asai’s lead is her “zeroth rule”, so she complies.
But in the period between Haruki’s Save Point and her Reset, Souma Sumire falls from the bridge, into the river, and dies, as we witnessed at the end of last week’s episode. Seeing her wearing the dress and holding the red umbrella rendered her a dead girl walking, and gave her last conversation with Asai far more significance than he could comprehend at the time.
When Haruki finds Asai quietly mourning on the rooftop, she demands he instruct her to reset…unaware she just did, and it’s too late. When she sees Asai crying, she can’t help but do the same. She’s following his lead, but also realizing that this is what the two of them have to stop from happening to others at all costs.
There’s a huge jump of two years to when Asai and Haruki, now high schoolers, are recruited by Tsushima into a Bureau-sanctioned “Service Club”, where they can erase sadness in an official (and supervised) capacity.
It’s a pretty jarring time leap, to be honest, but it means the first two episodes were always meant to be a prologue in which the pairing of Asai and Haruki was made and their shared calling revealed. Now the real work begins: both the sadness-erasure work, and the emotional-awakening-of-Haruki work.
