Lady Olivia Lastboss, daughter of a baron, is a reincarnated individual.

However, possessing immense magical power—far surpassing even the kingdom's royal family—she felt a profound sense of danger. Consequently, she concealed her abilities and grew up discreetly.

Only her father knew of her magic, but he tragically died protecting Duke Lohengrin, the head of a powerful faction.

As a result, Duke Lohengrin, seeking to protect Olivia, enters into a white marriage with her as his second wife.

To allow Olivia to fully enjoy her otaku lifestyle, the Lohengrin ducal family sets about eliminating any obstacles.
