レティシア・コンスタン

Human princess. The sole survivor of the royal family annihilated by Zenohemia and the five witches over a decade ago, a beautiful princess with blond hair and blue eyes. Now she lives in hiding somewhere on the island together with a small group of followers and her personal guard. She deeply despises the demon Zenohemia who destroyed her kingdom and massacred her family, she contemplates hiring Gilbert to achieve her goal of annihilating the demons on the island. Although naive to the ways of the world, she's certainly not arrogant nor uppity. A generous and forbearing soul. She survived the destruction of the royal palace during the demonic invasion and has lived on the run ever since. She has never lost hope of restoring her family's reign, when Gil arrives on the island and begins to make a name for himself defeating the previously indomitable witches she makes an active attempt to approach him for aid despite her adviser's warnings over the demon slayer's nature. She has suffered from vivid nightmares ever since she survived the razing of the palace. Later on it is revealed the nightmares are supernaturally induced. After Zenohemia is defeated, she commissions Gil and his party to sweep the site of the old palace which has been overrun by monsters. In addition, Gil is to find the royal seal which for generations has symbolised the legitimacy of the Constan family's reign. Despite repeatedly proposing Gil marry her and/or take up the position of head of the royal household guard, she is rebuffed each time. She eventually resigns herself to Gil leaving the island one day but swears no matter who she marries for political reasons her heart will always be his.
