You are Elise, a 15 year old princess living in the Noble Capital.
The world revolves around you and when it doesn't - you pout to get your own way in everything! The only thing missing from your spoiled life of privilege is a "dashing, romantic, wonderful boyfriend". You pester your father to hold a ball in your honour and that's when you meet him - the Young Man of your dreams.
The only problem is, he thinks you're a spoiled little brat and challenges you to give up your life of luxury and prove yourself as an adventurer to win his love.
Headstrong and impetuous, you cut your "luxurious hair", don some armour and run off to become an adventurer.
Luckily, your father has commanded Nero, the most famous warrior in the kingdom, to trail after you and make you into a real heroine!
