Reiko has an odd body posture, where she bents her elbows upwards and lets her hands dangle, which somewhat resembles ancient depictions of zombies, ghosts, and other undead creatures, alluding to her quirk.
- Reiko's name contains the kanji for "willow" (柳 Yanagi?), "child" (子 Ko?) and the Katakana letters of Rei (レイ?) which probably stand for "Spirit, Soul" (霊 Rei?).
- Reiko likes to surf.
