Primera Concerto is one of the heroines featured in Monster Girl Encyclopedia World Guide I: Fallen Maidens. A half-blooded archer who joined up with the forces of Lescatie after being rescued by Sasha Fullmoon.

A half-elf girl born between a human father and elven mother. Half-elves are persecuted by both humans and elves, and she was no exception to the rule. Since losing her parents when she was little, she's lived by herself, relying on no one until now. She has a prideful, moody personality and is easily swept by emotion, but she also has a sensitive and kind-hearted side. It troubles her that she gets overly emotional and ends up hurting others.

When she was attacked by monsters near the religious nation of Lescatie, she was saved by Sasha. She was then taken back (a bit coercively) and has since ended up living with at the church where "you" and Sasha live. She's an expert archer who is great with magic, which she can concentrate into arrows and shoot. Partly due to recommendations made by "you" and Sasha, she became a soldier of the Order. Right afterwards, she received the blessing of the chief god and awakened as a hero.

She acts like she hates humans and elves, but that is because humans and elves hate her. Also, she even hates herself for being a half elf, because the human and elven parents that she hates so much brought such a creature into the world. For that reason, she normally hates being in the city which is full of humans and spends most of her time alone in the forest near Lescatie. When she is given tasks by the Order, it's "your" job to go call her.

She thinks fondly of "you", since "you" treat her naturally without any fear, scorn, or posturing; for some reason, however, she gets upset whenever she looks at you and her anger is always irra­tional. She drives you away when you come to get her, and then she always looks back at you as you are leaving while regretting her treatment of "you".
