This is one of the main characters of the series and has a minor role in episode 1.

Hinata Miyake is a third-year high school student who switched from public school to homeschooling because of an incident that she's embarrassed of. After overhearing their plans and proving to be useful, she is invited to join Mari and Shirase on their journey to Antarctica. Hinata has a positive and energetic personality which serves as a disguise for the issues she's facing.

I prefer a voice that is similar to the character's in the sub: "Childishly Mature", energetic, articulate
