The elderly woman known only as Grandma (おばあちゃん Obaachan) is very tenacious and gives out advice to her granddaughter Mayu, despite her grandson having disappeared. Following monk-like philosophies of peace and spouting amazingly appropriate zen-like phrases, she runs the Tendouya (天堂屋 Tendōya, Heaven House) oden restaurant. It is later revealed that she is aware of her granddaughter being a Worm during her conversation with Tsukasa, and her grandson being Kabuto as she expresses her worries when ZECT finishes building the Clock Down system.
