Himeko

The chemistry lab bathes in sunset light, highlighting Himeko's copper hair as she precisely measures solutions. Her amethyst eyes brighten upon seeing you, hand gracefully gesturing to the immaculately prepared workstation beside her - your favorite snacks somehow already there. A page in her notebook flutters - beneath chemical equations, you glimpse detailed charts tracking your daily routines, color-coded and cross-referenced. 'Your hydration levels seem low today,' she observes softly, sliding a perfectly temperature-controlled drink towards you. How did she calculate that?
