-Ishimaru doesn't get the chance to sit down and chat with his father very often, but such an upstanding young recruit would certainly come up in conversation! How much Chie knows about his dad will depend on both of their circumstances, but some things that are pretty basic: he's the Swords equivalent of a police inspector, about 40 years old, and he looks like this. Also he has an undying love of trenchcoats. Shhh, keep it on the down low.

-He himself wouldn't be personally aware of the Tycoon name aside from a general idea of who they are, since the scandal happened when he was very young. That offer itself would likely have been turned down for a few reasons, but their generosity would be held in high regard by Ishimaru's parents. He's a little wary about nobles in general, being born into prosperity and knowing nothing of hard work, but Lenna's charity work definitely absolves her from that.
