Blend S (Japanese: ブレンド・S, Hepburn: Burendo Esu) is a standout 4-panel (4-koma) manga series by Miyuki Nakayama that perfectly blends workplace comedy with slice-of-life charm. Running from 2013 to 2022, the series became a global internet phenomenon following its 2017 anime debut, fueled by its infectious energy and the viral "Smile, Sweet, Sister..." meme. It is celebrated for its colorful cast and its playful deconstruction of "moe" character archetypes within the unique setting of a personality-themed café.

The plot follows Maika Sakuranomiya, a sweet-natured girl with a dream of studying abroad, who is repeatedly rejected from jobs due to her naturally menacing glare. When she tries to be friendly, she inadvertently looks like a cold-hearted villain. Her luck changes when she meets Dino, the eccentric manager of Café Stile, who recruits her specifically for her "scary" look to serve as the resident "Sadist" character. Alongside coworkers who play roles like the "Tsundere" and the "Idol," Maika must navigate the hilarious gap between her innocent personality and the cruel persona her customers crave.
