Taiga is the adult of Shirou's household in age-sense and protectiveness of Shirou, but not really in many other ways. Taiga is a Kendo master, teacher, and is full of over the top energy. In Carnival Phantasm, she is used in the Next Episode Previews at the end of the episode where she usually yells nonsense frequently and doesn't talk about the next episode.

As previously stated, bring all of the hyper energy possible for Taiga. I could see an adult medium-high to medium-low working here for Taiga.
