Technical note: Hanako has some Ketsurui samurai training, from back when she was Yui's servant and worked in the Empress' Palace surrounded by the Samurai until YE 27. Hanako was named Hinosami back then. She was also very close to Tsuya, the head of the samurai. An example of the two of them appearing in RP is
the wedding of Empress Ayame to Emperor Uesu. She is trained with swords and back before she lost all her possessions when the Captain's Suite was destroyed in battle, Hanako had a ninjato-style Zesuaium samurai sword.
