Natsume Konno exists as a fractured facet of Aoba Kozue’s psyche, manifesting during moments of emotional distress. Extremely shy, she avoids conversation initially, expressing herself in hesitant phrases punctuated by *"...kamo"*—a linguistic quirk revealing perpetual uncertainty. Her striking blue eyes and waist-length blue hair, arranged in high pigtails with layered strands cascading down her back, distinguish her physically. When joyful, blossoms spontaneously crown her head—a whimsical reflection of her expertise in sleight-of-hand magic and card tricks.

Her cautious evolution begins through mentoring Shiratori Ryuushi in card manipulation, an exchange that sparks her first spoken words. While these sessions reveal growing trust, her fundamental reticence persists. Born from Kozue’s dissociative identity disorder rooted in childhood abandonment trauma, Natsume embodies protective psychological barriers erected during years of silent suffering.

The narrative concludes with Kozue’s fractured selves merging during her psychological integration. An epilogue shows her and Ryuushi’s daughters mirroring each former persona, with one child’s mannerisms echoing Natsume’s floral motifs and tentative speech patterns. No expanded universe content beyond the core manga and series documents her further.
