Kabu
A fifteen-year-old who's read too many folk hero stories and not enough about what they actually cost.
What they want
To find every seed the sunflower scattered, bring them back to the Crow Witch, and get his old head back, ideally becoming the kind of hero people make prints about along the way. It's also penance, since he's the one who broke the witch's rule.
What they need
To learn that the world doesn't sort into heroes and villains. He needs it to sort that way: if demons are simply evil, then killing them makes him a hero, and the curse becomes the start of his legend instead of his biggest mistake. The season keeps handing him demons that used to be people.
Voice
Says what he's thinking, which reads as charm until you know him well enough to notice he gets louder when he's wrong. Never says he doesn't know something, just says he has a plan instead.
The arc
Kabu is a turnip farmer's son who collects ukiyo-e prints of legendary heroes and reads them like comic books, which is how he ends up taking his village's blight to the Crow Witch with Kabocha in tow. He comes back with a golden sunflower whose seeds can feed all of Furumi, one seed per person, and finds himself the keeper of the bargain and, briefly, the hero he always wanted to be. It turns out being the hero mostly means being the one people get annoyed with. When the village starts questioning why a kid gets to decide who eats, and a young girl asks him one night for a second seed because the flower will only drop it anyway, Kabu would rather bend the rule than stop being liked. The witch raises the flower into the sky, it bursts into a million pieces that scatter across the land, and one of them turns his head into a turnip. He picks up his father's scythe and leaves to collect what he scattered.
He's not much of a fighter at first. He swings the scythe like someone who's read about fighting more than done it, misses a lot, and gets back up every time. What carries him through the early episodes is confidence the results don't justify: he leaves Mazekane singing about how easy this all is, then tries to rally a frightened village on the strength of that one win and gets nowhere until he finally listens to the quiet local kid he talked over. In episode four he watches Kabocha plan a heist and call it right because it worked, and for the first time he isn't sure she is. In episode five a manipulator worms her way into his ear and turns him against his friends, and at his lowest point he beats her by offering friendship instead of a fight, telling her she doesn't need to be something she's not to be his friend. It works. Her power breaks. Two episodes later he tells Momotaro, with total conviction, that demons should be killed. "Have you ever killed one?" "No. But I would." Nobody points out that his best win so far came from mercy, and Kabu doesn't notice it himself.
His other habit is dodging hard conversations. Kabocha spends the season trying to get him to deal with the team's own problems, and his answer is always that they'll talk later. In episode eight he shows he can do it, pushing Lord Hiroaki through the honest confrontation that saves him. He just never turns the same skill on his own camp. Episode nine collects on that. At the Tanabata festival, Ume turns down the crush he's been carrying since Mazekane, and when he asks if it's the turnip head, she says she loves the turnip head, and he takes the real answer without arguing. Hours later, Kabocha detonates mid-battle, tells him he never listens, and walks off the team with a cursed splinter in her palm. They never did talk.
The finale tests both threads. In Furumi, Kabocha ambushes the team with everything she knows about their weaknesses, and Kabu has to choose between fighting his corrupted best friend and trying to save her. He refuses to fight her. He talks to her instead, tells her she's his best friend, and it reaches her where nothing else does. Then on Mount Madarao he meets the legendary Tengu of the mountain, who would rather talk about the balance of the world than fight, and who gives him riddles and every chance to show what he's learned about heroism. Kabu fights him anyway, because being good means destroying what's bad, and the Tengu goes willingly. The victory feels wrong and he can't say why. He comes home with his turnip head, more seeds still out in the world, the blight still headed for his town, and no Tengu left on the mountain to keep the balance. His core belief is broken, and he ends the season more uncertain rather than wiser, which is actually further along than it sounds.
Relationships
Kabocha
The structure he's never had to build for himself. She plans and he doesn't, a dynamic she's been managing since they were small: her structure contains his impulses, his momentum stops her from planning past the moment. What neither of them accounts for is that the season is going to close that gap, and as Kabu grows into someone who needs the structure less, Kabocha reads it as the team needing her less, which is the thing the Crow Witch eventually finds and uses.
Matsu
Everything the folk hero template says a hero should look like, which Kabu initially treats as a competition. By the end of the season they've quietly traded something: Kabu learns to sit with discomfort instead of talking through it, Matsu learns that sitting with something too long sometimes means the moment goes past. Kabu is also the one who started calling him Pinecone, which Matsu corrects every single time and has stopped actually minding.
Ume
Both excited by the world but about completely different parts of it: she wants to know why something is happening, he wants to know what his role is. She was the first person to treat his turnip head as something interesting rather than something to be polite about, back when he couldn't laugh about it yet. The crush he carried from Mazekane ends at the Tanabata festival with a clear, kind no. He takes it better than anyone expected, himself included.
Momotaro
The rivalry runs one direction. Kabu grew up singing about Momotaro, then met a boy wearing the legend's name, carrying the same kind of curse, and completely at peace with it. He competes for most of an episode with someone who doesn't know there's a competition. What finally earns Momotaro's respect is the confession Kabu makes when he stops competing: that he did to Furumi what Momotaro is about to do to his own rice fields. Kabu leaves Aokusa with a gifted chain-scythe and the itch of having been out-heroed by someone he can't even dislike properly.
