This article is about a/an Native in Kamen Rider Decade.
For the original Kamen Rider Kabuto character, see Hiyori Kusakabe.

Mayu (マユ Mayu) lives with Grandma and has a grudge against Kabuto for what she thought was her brother's murder. She later encountered her 'brother', who was actually a Worm who had mimicked her brother, and was revealed that she is the Sisyra Worm. It was also revealed that she was being targeted by the other Worms because of her ties to Kabuto. After learning the truth, Mayu went to see Souji to apologize, but only saw a smiling Souji as Kabuto returned to being stuck in the Clock-Up Zone.
