Soft Bell is a massive, voluptuous, lime-green and black robotic tank girl with a turret head and hourglass frame. Despite her heavy armor and face-mounted cannon, she is a mute, sweet-natured giant who loves hugging Lady Cleang. She fights only to protect Cleang from Awth's assassins, Whale and Yotiny, after Cleang's father, Thefto, was killed by the fallen angel. Soft Bell fires powerful shells—loaded into her rear by Cleang—and uses arm chainsaws. She serves as her loyal, innocent guardian!
