Hannah is Howdy's childhood friend. She is one of the very few who can stand Howdy's jokes. In fact, she claims to find them endearing, and knows every one of his jokes so well that she can state the punchlines before he does. All of the Ham-Hams think she is pretty.
In Hannah is in Love!, Hannah comes to visit Howdy, and is introduced to the other Ham-Hams. During her short stay, she developed a crush on Dexter; in part due to Dexter's "flattering" correction of calling her "just perfect". Hannah and Dexter went on a date in the Ham-Ham Fun Park together; but Hannah decided that Dexter was a "wimp" because of his cowardly reaction to the rides. After their date, Hannah's crush on Dexter died out.
In the English dub, she has a soft voice with a country accent.
- Hannah (alongside Howdy) seems to intentionally resemble an Asian stereotype, with squinty eyes and a common Japanese hairstyle. This is likely why she was changed to be Southern in the English dub, as the design would be deemed far more offensive outside of Japan.
- Hannah's Japanese dub voice actress, Hanako Yamada, is a stand-up comedian. It is likely that Hannah's personality was modeled after her voice actress.
- Hannah did not have any major episode roles after her debut. However, she does have minor cameos in Go Go, Ham-Hams!, Start, Ham-Hams!, and Happy Ham-Ham Wedding!.
