Yumina Ernea Belfast (ユミナ・エルネア・ベルファスト Yumina Erunea Berufasuto?) is one of the heroines In Another World With My Smartphone. Yumina is also the crown princess of the Kingdom of Belfast and she is currently traveling with Touya and everyone else.


Yumina has long blonde hair with green eyes (most of the time). Before meeting Touya, Yumina wears a dress for a royal attire. Later when joining the guild, Yumina begins to wear a white blouse with a blue ribbon, and a black top over that.[1]


Yumina is a polite and careful person who is an exemplary member of royalty. However, Yumina's actions for a princess are surprisingly bold.
