Let’s shine a light on the star of this design: Eiai Nano. A core member of Rentarou’s circle of fated lovers, Nano stands out as the series’ resident “genius prodigy”—she’s endlessly curious, has a knack for inventing (even if her creations sometimes go hilariously off-track), and approaches life with a childlike wonder that pairs perfectly with her sharp intellect. At first glance, she might seem focused on her latest experiment or rambling about a new scientific fact, but beneath that curious exterior lies a deeply caring heart: she’ll drop everything to help her friends, uses her smarts to solve their problems (often with adorable, over-the-top solutions), and loves Rentarou with a sincerity that’s as sweet as it is genuine. With her signature short, messy silver hair, round, wide eyes that light up when she talks about science, and a style that mixes casual comfort (think oversized lab coats over simple tees, or soft sweaters for lazy days) with a touch of whimsy, Nano feels like a breath of fresh air—relatable for anyone who’s ever gotten lost in a hobby, and endearing for her unapologetic love of learning. For fans who adore her mix of brains and heart, this pillow is a must-have.
