Marinette is the sole survivor of a clan of Spirit World warriors with the power to employ their blood as weapons. As such, Marinette is tasked with hunting down and killing "akuma"—creatures said to be the manifestation of negative human emotions. One day, while deep in thought on the school roof, Marinette comes across Adrien Agreste, a rare half-breed of akuma in human form. In a panicked state, she plunges her blood saber into him only to realize that he's an immortal being. From then on, the two form an impromptu friendship that revolves around Marinette constantly trying to kill Adrien, in an effort to boost her own wavering confidence as a Spirit World warrior. Eventually, Adrien also manages to convince her to join the Literary Club, which houses two other powerful Spirit World warriors, Nino and Alya Lahiffe.

As the group's bond strengthens, however, so does the tenacity of the akuma around them. Their misadventures will soon turn into a fight for survival as the inevitable release of the most powerful akuma, Hawkmoth, approaches.

No glasses for Alya and Nino, just for Marinette.
