Akira Oda (VA: Takeo Otsuka)
A perfectly ordinary second-year high school student with a sharp gaze and a blunt attitude.
He is well known in his class for his lack of presence and shows little interest in others, to the point of not remembering most of his classmates’ names. However, he deeply cares about his family and close friends.
His weapon of choice is Yato-no-Kami, the sword once wielded by the first Hero.

Amelia Rosequartz (VA: Saku Mizuno)
A princess of the Elven royal family.
She is a Silver-rank adventurer who excels in combat and can fight on her own. Usually quiet and aloof, she begins to show emotions and expressions after being saved by Akira.
She also has quite the appetite.

Night (VA: Sanae Kobayashi)
A monster of the Black Cat race who usually takes the form of an ordinary black cat.
