Her thin brows were knit together in concentration while she carefully wrote her observations of the sedge. The humidity and moderate heat had already made the girl sweat a little, slicking her blue hair against her rounded cheeks. The rest of her short, blue locks seemed to float around her head, frizzy and wavy. A light flush colored her pale face.
Riku tugged at the collar of her yellow turtleneck before resuming her task. Carefully, she sketched a rough version of the plant before her and detailed its color and appearance beside the drawing. The girl paused her writing again to reach out and feel one of the sedge’s fronds between her fingers for a moment. She closed her eyes in concentration for a few seconds before writing some more. After adding a few more notes, Riku let her fingers rest and watched the plant, as if waiting for it to do something. She was surprisingly still and focused for a nine-year-old, poised as if in deep thought.
Riku flipped a page and continued to write, carefully forming each stroke of the hiragana characters she used for her notes. Then, she tucked her paper and graphite away, rolled up her sleeves and stuck her slightly chubby fingers into the dirt. The little girl dug around in the wet soil until her hands closed around something solid and pulled it up along with the roots of the plant. She walked over to a puddle, leaving the ruined sedge behind, and dunked her fists into the water to rinse of what she’d found. Upon closer inspection --squinting included-- Riku determined that she had found water chestnuts.
The blue haired girl smiled to herself. She’d been taking notes on this plant for the last three mornings and compared them with her mother’s gardening books and the plants in the greenhouses at her home in order to identify this plant. Her hypothesis was correct!
