Hanako Hayashi

Hanako Hayashi is the socialite daughter of Japanese ambassadors in the one-shot. She is played by Erika Ishii.

Background
At some point in her past, Hana learned to pick locks. Rupert Merriweather caught Hanako stealing a necklace. Bentley Badger was also aware of her attempted theft. Mr. Merriweather used this incident to blackmail her so she would take part in the heist in the Crystal Palace.

Alexandra O'Neil
Hana and Alexandra know each other, and Alexandra knows Hana's parents.

Parents
Hana's parents are Japanese ambassadors. They seem to know of some of her more unruly behavior, but not the extent of her actions, such as the attempted theft of Merriweather's necklace.

Nyan
Nyan is Hana's cat, a well-bred fluffy Persian.

Trivia

 * Taliesin's described his inspiration for Hanako's character on the Critical Role blog as follows: "I’ll take any opportunity to delve into the “old research” files. I had some research on the Japanese community in London during the 1890s left over from a project I completed in 2004, and I tempted Erika into exploring a community that I felt had gotten next to no pop culture exploration in general (let alone the game space). So I presented Baroness Hayashi, wife of Tadasu Hayashi, Japanese Ambassador to the United Kingdom. The accomplishments of this power couple are too numerous to list, but it is worth noting she had a great deal of success promoting jiu-jitsu to the gentry of London (women especially). And while I managed to find a bit of information on her son and granddaughter, there was a daughter that my research failed to paint any picture of.  So I pitched Erika an Arsène Lupin cat burglar archetype: an Oxford-educated (uncredentialed, but not completely uncommon) young woman of means who was a thrill thief by night. Add the motivation of reacquiring a cultural relic, and it was too good not to play with — which gave us a thief that had an excuse to be involved the cat show."
