I really hope you can work on it soon, particularly with Hana. Fuuma seems a bit more present overall, and it fits his personality to be quiet, so it's not a big deal. But Hana's a character who could easily thread with most people in the game, and yet months later it still feels like she's mostly only had an intro and never had any developments or built any significant CR.
Your voices for both characters are wonderful, so I have no crit to offer there, it'd just be great to see them around more often.
