Ai is a light headed, pink haired middle-school girl who always forgets her glasses. She usually speaks like a warrior which has been passed onto her by her father, she only speaks this way of interest or getting something done, and she also loves learning about sea creatures. She's also very straightforward and has a monotone voice when talking without her glasses on. Without her glasses she always squints giving her a cute face because she can't see well without her glasses.
