Zin is quiet, seemingly portrayed as a shy, fragile girl, completely opposite of her tomboyish counterpart. She usually is seen hiding behind Kuren, or picking flowers, making pretty necklaces from the stems.
Zenne is the over-protective twin, who guards his sister threatening to bite, or attack if anyone touches his sister… Despite that fact, Kuren isn't befriended with her, but just wishes to keep her safe from anyone who would try to hurt her…
In RP, the twins were created in a lab accident, trying to create weaponized Vocaloids, who were sick of human-kind.. Sadly, due to the accident, these two were created, yet immediately deactivated, and thrown away, until their Master (Real creator, RenaKerensky) found them, and took them back to the mansion..
