Rena Mamiya

The was the first executive leader Worm who posed as , a woman whose childhood dream was to be an opera singer. 
==Biography==
Her true form is Uca Worm, the first executive Worm. She has a large claw for the right arm capable to tearing through steel, a shield for the left arm, and has a thick shell. A cruel and clever planner, she is the one who ordered a Worm to capture (or kill) Jyuka. In Worm form, she is very powerful and on her first debut, she defeated both TheBee and Drake. Soon after, she discovers the existence of the Hyper Zecter and attempts to retrieve it after she shoved Renge off a building, only to get caught in an explosion when the hidden bomb within the Hyper Zecter case explodes.
She lost her memories as a Worm temporarily after being hit in the head by Hyper Kabuto's Hyper Sting attack. The original Rena was a talented singer with a kind heart that wanted to help people. Believing herself to be Rena, she chases after her dream of being an opera singer until her Worm persona eventually resurfaced. During that period, she met Daisuke & they fell in love with each other. She is able to sing one more requiem for Daisuke on stage, expressing her gratitude to him. After Daisuke, as Kamen Rider Drake destroys her in her Worm form - accordingly to her wishes - she remembers her feelings for him before dying in his arms.
