Kazuki wakes up, but is too out of it to notice that Enta was just kissing him. Enta is direct with the audience: he’s in love with Kazuki. He has been for a long time, ever since they were the unstoppable “Golden Duo” in soccer, complete with a signature pose. Enta has to contend with a lot of kissing the next day, as his big sister Otone is going on a fishing trip with her boyfriend.
The episode plays with the fact that kisu is not just how you say “kiss,” but the Japanese name for Sillago japonica, or Japanese whiting. The city idol declares it’s kisu day, and in lieu of someone to kiss (that he knows of), Kazuki tries in vain to go to a fishmonger for a “kisu selfie” for Haruka.
While playing cards with Haruka (who “Sara” texts to apologize for the selfie being late), Enta learns that Kazuki isn’t laughing around his little brother either ever since quitting soccer. Enta wants to use the wish from the next dish of hope to reunite the Golden Duo.
Enta even fantasizes about Kazuki coming around on his own and letting him tie the miçanga to his ankle – the symbol of their soccer brotherhood as well as a token of affection. But no—it’s just Otone, who runs off with the anklet for her date.
As Enta defends the spot by the river where he and Kazuki used to practice by getting into a fight with two other players, the two “Otter” cops create another Kappa Zombie, this one from Otone’s kisu-loving boyfriend. His head takes the form of a kisu, but he’s a Don Juan who has many women and many kisses, obsessed with quantity over quality.
Enta fantasizes again that Kazuki comes to rescue him, but it’s just Kuji, who doesn’t get why Enta got in a fight he had no chance of winning. Enta is committed to protecting the Golden Duo’s practice spot…in the off-chance Kazuki comes back to him.
The Kappa Zombie alert is then sounded (with Sara doing a wonderful homage to Castle in the Sky), and rather than cats last week the sky is full of brides, all of them drawn to the zombie, who turns them to kisu with a kiss. The three lads are transformed by Keppi, do their attack song and dance, and extract the zombie’s shirikodama.
All three parts of the ensuing sarazanmai are related to Enta’s long-standing secret crush on Kazuki. We see Enta smelling Kazuki’s clothes, playing his recorder (for an indirect kiss), and finally his more recent kiss with a sleeping Sara!Kazuki.
The zombie thus vanquished and its desire assimilated, Otone and all the other women wake up and completely forget Mr. Kisu…as if he had never existed. He even disappears from photos, Back to the Future-style! Enta confesses his love to Kazuki and just when they seem poised to kiss, it’s only another fantasy; “Kazuki” is just Keppi.
Thanks to Kazuki’s obliviousness and Kuji’s lack of really caring, Enta’s secret seems to be secure—or at least emotionally tabled—for now. The next time he’s with Haruka (who we see in a wheelchair for the first time), Enta declares he’s going to “give up” on trying to win Kazuki over.
Part of that is that he saw a random mouse making off with the miçanga meant for Kazuki as a sign that it’s not to be. But then Haruka produces Kazuki’s original miçanga, saved from the trash, and asks Enta to keep trying to get Kazuki back into soccer.
Meanwhile, the Otter Cops are scolded by their boss, who is “otterly” furious at their lack of progress due to kappa-related interference (I hope he’s just a giant talking otter, for the record). With his frustration in mind, I wonder how much longer the kappa zombie fights will remain as easy as they’ve been.
