(When creating Kaiju, she secretly digs up corpses from the Heroes' graveyard to experiment on.) Her speech is usually accompanied by a smile and closed eyes— (She expresses madness and cold-bloodedness by actively using a uniquely cunning and creepy laugh.

FlowPin told God that she wanted to be with her precious people for a lifetime, and because of those words, God gave her the ability to regenerate. Afterward, she joined the Sandbox Sentai and fought alongside her hero comrades, but most died in battle. Finally, when someone presumed to be her lover or a close colleague died leaving only a brooch, she fell into despair. As she sat in the hero cemetery cursing her ability and lamenting her fate, Alice-ing approached her. Alice-ing told her she did nothing wrong, and instead insulted the deceased heroes, saying they were the ones at fault for choosing death and leaving her behind. She claimed that if there were no love, FlowPin wouldn't be suffering, and persuaded her to join the Black World. Then, she stabbed a brainwashing syringe into FlowPin's back. When King Blue greets her after a long time, she tries to slash him with her axes, but keeps missing due to his ability. She glares at him, grimacing, and asks why he appeared in the world again instead of just sleeping in his coffin. (Presumed to be hostile toward King Blue for some reason related to the past.)
