Leonie joined up with the mercenaries formerly led by Jeralt. As his greatest apprentice, she quickly took on a leadership role, and eventually even inherited the title of Blade Breaker. No matter where she went, however, she was burdened with Jeralt's unpaid tavern tabs. Angry with Alois for pushing these debts upon her, she went to see him with the intention of forcing him to pay half the debt. But when she arrived, she found a suntanned Alois happily lounging after a hard day's work on his family farm. Leonie found herself unable to go through with it. She did become a world-renowned mercenary, but she spent the whole of her career paying off debt.
