Not long after Haruka was born, Kazuki gleaned from his grandfather’s dying words that his mother wasn’t his biological mother, and ever since felt disconnected from the family as a non-member, despite all the love they gave him.
It’s not so much that he hated his brother, as he said last week, but he hated the whole situation of him and his brother not actually being related by blood. Why it matters so much to him that they are connected by blood, but there it is.
In the present, Toi captures Sara’s manager and escorts her away from her fan meet-up event, but finds she’s not quite human, and thus capable of transforming into a little critter who can squeeze out of any confinement.
Kazuki fares rather well as Sara’s double, at least where Haruka’s concerned, but things go pear-shaped fast when both the manager and the real Sara arrive in the hall and the former removes Kazuki’s wig. And that’s it: his secret is out. Now Haruka knows all those texts were just from him.
As all this is going on, the Otter Cop Duo wrings the desire from a man obsessed with sachets of a very specific smell, creating a new Kappa Zombie boss.
The three kappaboys do their song-and-dance, but when the Sarazanmai comes, and Kazuki’s memory of finally reuniting with his true mother in secret, the smell of her sachet he remembers is the same as the sachet Haruka always carries.
Whatever that means, the three kappaboys are ripped out of the tunnel of water, their work to extract the shirikodama still incomplete.
Keppi is so mad he can boil tea on his belly, and asserts to the boys that they won’t get their human forms back or get a dish of hope until they defeat the Sachet Zombie. Kazuki shares more about his meeting with his mother with Toi and Enta, culminating in him deciding to stay with Haruka and his non-biological parents.
Even so, before he returns to them, Haruka runs (that’s right runs on his functioning legs) to beg Kazuki to come back, fearing he’s going away. Kazuki spurns him rather harshly and walks off, but Haruka follows him…and gets hit by a car.
Now, every time Kazuki sees Haruka in his wheelchair, he’s reminded of what he did to him, and simply can’t bear it, which is why he adopted the Sara clone routine to make a faux connection with him from a safe distance. But odds are Haruka already forgave Kazuki a long time ago, and couldn’t care less if they have different mothers.
