Natsuko is the opposite of your social butterfly. He is a very timid and shy individual who always has the tendencies to overthink his words, and what and how he speaks. He is passionate about his craft though, which is why he’s a bit more talkative when sharing his to other people. He’s very emotional, shameful, but is a very sweet, and down to earth, beach boy.

Natsuko’s voice is soft but still masculine. Say if he were to talk to you in his neutral voice, it would be  medium, and subdued, but when he’s in panic or were to be in distress, his voice reaches a higher and more frail pitch and tone of vocal masculinity, especially when he's crying which brings me to my next point. You should also have the ability to voice-act crying really well.
