Muyoku no Seijo

A boy named Leo, who values money above all else, finds himself in an unexpected situation where he swaps bodies with Leona, a beautiful young marchioness who has been wrongfully accused and lost her noble status. To avoid returning to the academy filled with nobles, Leona uses sorcery to escape, and Leo, enticed by a generous reward, takes her place. As a member of nobility, Leo would normally be rejected, but his new appearance and unusual priorities lead others to believe he is a "Pure Maiden." This mistaken identity draws the attention of a marquis couple, an imperial princess, and the first imperial prince. The story follows Leonora Von Halkenberg, who becomes known as the "Altruistic Saintess."
