Ougai is talented and charismatic, being a novelist, translator, and army surgeon. Having lived abroad, he’s more open to new things than the average Japanese person of that era. He lives in the same mansion with Hishida Shunsou.
He’s charismatic, romantic and very gentleman-like, although quite persistent when he wants to be. Also, as Shunsou puts it, a weirdo as well.
