Silva.

Silva is a carefree, perpetually cheerful girl who wields a massive scythe and proudly declares herself a member of a sinister evil organization. Despite her dark affiliations and imposing weapon, she transfers into an entirely ordinary high school, where her daily life quickly becomes anything but normal. Rather than terrorizing the student body, Silva effortlessly befriends her new classmates while simultaneously carrying out her villainous duties, which include clashing with self-proclaimed heroes of justice and actively recruiting fresh members for her mysterious syndicate. This comedic manga thrives on blurring the boundaries between good and evil, making it frequently impossible to determine which side is truly righteous. The story features a colorful cast that includes questionable magical girls, hopelessly incompetent adults, and an unexpected abundance of pudding. Through its lighthearted tone and absurd situations, Silva delivers a uniquely entertaining narrative where world-ending threats and mundane high school antics collide in perfect harmony.
