Kamado Nezuko

If you want the most iconic little sister in modern anime history, you definitely already know Kamado Nezuko.

Her visual design is completely distinctive and totally iconic. Nezuko sports gorgeous long black hair that fades to bright orange tips. Her beautiful and expressive eyes are pink, enough to melt your heart. She’s rocking her signature pink kimono and that totally classic bamboo muzzle that hides her demon fangs. Her amazing gap moe is what makes her such a universally loved waifu and imouto. She’s a totally adorable, head-pat loving toddler most of the time. She's going to physically shrink herself into a wooden box. But when someone threatens her brother she instantly becomes a totally badass demon who kicks her enemies completely in half with flaming blood magic.

The fanart community goes absolutely nuts for her awesome duality. Artists love drawing her adorable smol form doing cute everyday stuff. You will also find absolutely breathtaking desktop wallpapers of her effortlessly unleashing her explosive pink Blood Demon Art.
