Setsuna is a character who exudes an aura of calm and quiet, although this, contrary to being due to her being well-trained and disciplined, stems instead from her chronic absentmindedness and laziness. Her absentmindedness has, on multiple occasions, seen her blissfully walking into traps without once realising the danger that is presented to herself, the result of her daydreaming and losing focus of the path ahead of her. Even after being ensnared by traps, Setsuna is known to treat her predicament with bemused apathy, believing that Hinoka will always somehow manage to locate and rescue her from her plight.
