ブラコンの姉に実は最強魔法士だとバレた。もう学園で実力を隠せない

Sleeping and lazing around all the time. Such was the indulgent life chosen by Alvin, the son of the Astarea Duke’s household.

His father was the commander of the Kingdom’s knight order, his mother a former vice commander of the magic division, and his non-biological sister held the top position in the academy, serving as the vice commander of the academy’s knight order.

All members of his family were outstanding. Perhaps due to this, everyone around him ridiculed Alvin for his indolent lifestyle, calling him the ‘stain on the Duke’s family’. However, Alvin paid no mind to such ill-repute.

“Because a lazy life is so much more wonderful!”

Little did they know, Alvin was, in fact, the strongest magician in history.

And one day, while defeating a band of thieves all on his own, his true abilities were discovered. Moreover, his beloved sister found out about it…

“As expected, Al-kun is such a capable boy! I have to tell everyone about this…”

“Stop it, nee-san! There is a certain reason for which I hid my strength…”

“So, Al-kun will join the knight order with me! It’s easier for everyone to acknowledge you that way! That’s a brilliant plan!”

“…Sorry, nee-san. I won’t accept it no matter what.”

This is a story of a boy who desired a lazy life and his abilities were revealed to others, entwining him in various situations. It’s a tale of a kind-hearted young man who goes on to save someone—despite being called a “stain,” he refuses to silently overlook others getting hurt because he’s not a scoundrel.
