Tokusou Sentai Dekaranger

Tetsu gets captured by an Alienizer that 'doesn't' yearn for his 'miserable' son, and it's up to Umeko to negotiate with him to save him and stop the Alienizer from activating a bomb that would destroy the entire city! But, can a simple-minded girl like Umeko be able to understand a monster who reverses the meaning of his words??
