First person: I (soft, polite). Second person: you (polite). Slightly short, fluffy silver hair like ocean waves. A bandage covers his left eye. He is tall and thin for his age (a so-called beanpole). Although he is a boy, he wears a purple kosode decorated with a wood sorrel crest. Fire attribute (capable of producing flames). Born into a samurai family, he is always spacing out and has a quiet, frail personality, leading his father to worry if he can truly survive in this era. He is quite caring toward others. He is sometimes mocked behind his back by surrounding adults and children as a "Princess Boy." Only Mankichi, who will later be known to history as having "Insight," knows the hidden strength sleeping deep within the weak and ridiculed Yasaburo—a strength that will eventually blossom into greatness.

First person: I (literary, humble). Second person: you (casual, friendly). Long, fluffy black hair like a girl's. He reportedly has a birthmark on his forehead above his right eye, so he hides both eyes behind his bangs. His long hair in the back is loosely tied. He is small, fragile, and trips often. He wears a dull greenish-brown kimono with slightly frayed hems from getting caught on things. Wind attribute (capable of creating small tornadoes). A quiet, bookish boy. He uses a literary first-person pronoun in imitation of the many books he reads. He is clever but extremely good-natured and slow-witted when it comes to social cues, making him easily trust others. He has a bit of a lonely side. Born with terrible luck, he is a klutz and a victim of bullying. People say he is "fun to tease." Because of his extraordinary misfortune, adults and children alike whisper behind his back or avoid him as if he were a bringer of pestilence. Though born to a samurai house, he is so obsessed with books and waka poetry that monks sometimes scold him, saying, "This is an age of military strategy."
