Troisienne was the quieter, more composed of the two but equally admired by both Ascoeur and Q-feuille, although arguably closer to the latter due to her otaku tendancies. Her ability allowed her to literally stop time, but she was only able to do this a few times before becoming fatigued as it produced a great strain on her body. Like Trixie, her sudden and violent death had a great impact upon Ascoeur and Q-feuille, as well as representing a change in tone for the series.
