Titania is a person who I both like and don't like.
I like her because she has a zero-tolerance policy for bullshit. She's the kind of person who if she had a customer service job and a customer was being unreasonable and dumb, would have no problems telling the customer to fuck off.
I don't like how hard-headed (pun intended) she was when dealing with Taka. Her relationship with Amaria gives her good reason to want him to just quit if he doesn't like it. But she sees what his father or other members of Team Meteor might do to him as irrelevant. She actually thinks it's as easy as just saying "I quit", which she shouldn't since she couldn't do that with Amaria, and still can't when she has amnesia about the whole incident.
