Hideko Gotoh is socially anxious and shy, always leading to her stumble over her words or completely freeze up. Because of her anxiety and "glass half full" mentality, she chooses to hide where it's safe, which is the inside of her room, spent playing her bass and writing songs for the imaginary band in her head. She does wish to overcome these fears, however. She just needs a little boost is all.

Hideko's voice should be soft and higher pitched as she is on the shy side. She isn't very sure of herself.
