Where did Kazuki originally get his miçanga? From Toi, years ago, after he shot his brother’s foe. His brother had given up so much for him, he wanted to return the favor, and so gave up soccer, just like Kazuki would end up doing after Haruka’s injury. The thing is, Kazuki doesn’t remember.
That may be part of the equation of why Toi is alright leaving Kazuki and Enta, but it doesn’t mean he’s okay with it. Still, family comes first, and Toi would do anything for his brother. Unfortunately, Chikai is such a selfish jerk that he exploits Toi’s utter devotion to him at every turn, not letting him have his own life. “You need me, I need you.” Neither is true; not anymore.
On the contrary, Toi would be better off if his rotten brother were apprehended and faced justice. He has new connections. Not to be cold with regard to Chikai—he may well genuinely love his brother and wants them to be together. But he’s also an adult who made his choices, which come with consequences.
That he’s okay with Toi getting dragged down with him out of fraternal loyalty is proof of Chikai’s self-serving nature. More proof? Relying on a 14-year-old stranger in Enta to keep him hidden from the roaming Otter policemen. At least during this interaction, Enta learns the truth about the origin of Kazuki’s miçanga, and that Kazuki an Toi’s connection goes back further than he thought.
While the sudden presence of the “bro” of the guy Chikai (though technically Toi) killed wanting revenge seems rather sudden and contrived, when Chikai tosses Enta in the line of the guy’s sword, it’s Strike Three; dude should be in jail.
Thankfully for Enta, Reo and Mabo rescue him from the gangster, and then Reo shoots said gangster dead. Two other police hear the shot, but he and Mabo use special otter pins to brainwash them into telling the story of their choosing.
In a theater, Keppi consults with Sara on the Otter situation, and Sara unveils an apparatus that will flash freeze them alive upon capture, all to get back “Dark Keppi.” It’s interesting to see these two work so closely together, and to see Sara’s intermittent extreme clumsiness on display as she sneezes from pepper and accidentally kicks Keppi into the device, freezing him.
When Toi calls Enta to say his farewells, Enta tells him he knows about the miçanga, but that Kazuki doesn’t realize it’s Toi who gave it to him. Toi doesn’t think it matters, nor is there any reason to tell him, and says goodbye, wishing Enta and Kazuki the best as the Golden Duo.
When Toi calls Kazuki, he tests him by saying the same words he said years ago about having to “protect the connections he has.” Kazuki assumes, quite wrongly, that Toi is leaving because Enta betrayed them and stole the Dishes of Hope.
That makes Enta’s next encounter with Kazuki fraught with a great deal of anger and sadness over the misunderstanding. Even though Enta returns with the dishes and urges Kazuki to hurry up and help him get Toi back, Kazuki is still burning from Enta’s betrayal, and won’t believe or even listen to another word he says.
This is how, on the same day his friend Toi leaves his life, possibly never to be seen again, Kazuki puts all the blame on Enta and disowns him as a friend. To make matters worses, Keppi is nowhere to be found and thus can’t protect them when Reo and Mabo show up in the park.
Reo pulls out his pistol and shoots, and Enta takes the bullet for Kazuki…a love bullet! As the cops leave with the dishes, Mabo tells Kazuki he may still have time to save Enta’s life, and Enta comes to sprawled over Kazuki’s lap, and laughs that he couldn’t even joke about ever hating him before passing out again.
No doubt unsure what else to do, Kazuki calls Toi, but Toi is already on the boat out of Tokyo with his brother, and doesn’t bother answering. One imagines if Kazuki texted him that Enta got shot, he might ask the boat to turn around, but Kazuki doesn’t text him, so he doesn’t know how dire things are back on land.
With Kazuki a definite emotional wreck, Enta possibly dead, Toi on a boat and Keppi an ice kappa-cube, the Otters couldn’t be in a stronger position, nor could the good guys be mired in a deeper abyss of despair. Where does Sarazanmai go from here?
