Born as the Princess of War, touted as the greatest mage, her name was Leticiel. She lost her family and husband to the neighbouring kingdom’s invasion. In order to prevent her power from falling into enemy hands, Leticiel took her own life… or that was what was supposed to happen. Instead, she woke up to see an unfamiliar ceiling.

After gathering information, Leticiel realized she had somehow transmigrated into another person living a thousand years after. To make things worse, she was a "talentless" lady who was shunned by her acquaintances and family, her fiancé was even cheating on her with her sister. There were many issues she wanted to complain about, but when she witnessed the magecraft of the world from a thousand years after… “Magecraft Maniac” Leticiel was livid at its lameness.

“The magecraft level in this world is too looooow!!!”

The tale of an eccentric Royal Highness blasting open her path in life using the strongest magecraft, begins!
