Eruto, whose magic power level was almost zero.

He attended a Magic Academy, but his virtually non-existent magic power proved to be his undoing, leaving him at the bottom of the academy's rankings.

He became a target for both teachers and students, was bullied by them, and consequently expelled within six months.

Despite knowing he was innocent.

One day, a month later.

In the royal capital, Eruto single-handedly stopped a runaway carriage, suffering severe injuries in the process.

The occupants of the carriage were none other than the princesses from various countries, collectively known as the "Top 5" at the academy.

This incident prompted the princesses to recognize Eruto's kind heart. Eventually, the five of them pledged to protect him, and the academy, too, began to acknowledge his abilities.

Eruto, in turn, finds himself embroiled in the issues of the princesses' home countries and beyond.
