Alicia in the anime might be many things, but so far there is little to show her being a tsundere. (And i loathe tsunderes, so would smell one from miles away
). She is most definitely rash and impulsive, overreacts on general basis and doesn't seem to have much going for her in terms of critical thinking capabilities ... but a tsundere she is not. Yet, at the very least - the way she is set up wouldn't surprise me if she does turn out that way along the way, but she is not there yet. Oh well, at least she seems to fulfill her role of making funny facial expressions good enough to keep me entertained
