As a reminder, not only we decide whether if she is tsundere or not, this thread also serves as a purpose to discuss her level of tsundere-ness. In scale of 1 to 5, rate her according to what you’ve learned in the anime, manga, game, or novel she's featured in.
Don't recognize the featured character? It's cool, you can post in this thread saying so or skip ahead. When you recognize her eventually, come back for this poll. If you want to see the result without voting, click the "View Results” link in the bottom right of the poll.
I've recently finished sola; I don't see her as a tsundere. She's usually kind to everyone accept towards Takeshi, on some occasions. But she only gets "angry" when he doesn't live up to her (impossible) expectations. Those could be called light tsundere characteristics.
