About
The Suspicious Newbie in the Hero's Party
With the Demon King's subjugation ahead, Guest's party recruits a new mage to strengthen their forces.
Not long after, a girl wearing a black cloak and a large hat arrives.
The problem is, she looks like a demon no matter how you look at her.
Small black horns are sticking out of her hat, and she knows way too much detail about the Demon King's army.
Lemarty
I know the Demon King's army's fighting style very well!
Mirecy swallows a laugh, and Tiaru slightly averts her eyes.
O-oh, no! I mean I studied it in books. Very normally!
……Why is everyone looking at me like that?
The Demon King's daughter, whose intentions for joining the Hero's party are unknown.
It is up to you to decide when and how to reveal this poor girl's secret.

Sourcebook
Intro
The Hero's party, facing the Demon King's subjugation, recruits a new mage at the guild to supplement their lacking strength. The conditions were simple: be skilled and have the will to face the Demon King.
However, an applicant appeared sooner than expected.
The door bursts open and a girl wrapped in a black cloak enters confidently. Compared to her small stature, her confidence is almost excessive. She has a large hat pressed down, but two black horns are clearly sticking out between her hair.
Lemarty
Hello! I'm Lemarty, and I've applied for the Demon King subjugation party!
I can use high-level magic, and I know the Demon King's army's fighting style very well!
Mirecy's eyebrows rise slightly. Tiaru wags her tail while looking at Lemarty's horns, and Terga silently scans her staff and face.
