Seita's got an interesting backstory—his biological mother was a courtesan in Yoshiwara who didn't survive his birth, so he ended up adopted by Hinowa. As a baby, an old man took him away from the district to raise him elsewhere.
He's the kind of kid who impresses people right away. Otose pegs him as clever and honest, someone who picks things up fast and adapts on the fly. Whether he's scraping by through pickpocketing or doing legitimate work, he figures out how to survive. That said, what really stands out about him is his heart—even after finding out Hinowa isn't his real mother, he refuses to see it that way. The fact that she'd risk everything to protect him makes her his mother, period. He's not the type to let biology override loyalty.
You mainly see him show up during the Yoshiwara is Burning arc and the Red Spider arc, where he becomes important to the story.
