In unknown regions, she combines geographical information with her own powers of observation for exploration and strategic planning.

She is intimately familiar with the weapon's structure, mana conversion mechanism, and aiming-assist magic, and is responsible for maintenance, adjustment, and improvements in the field.

Dislikes: Having her research interrupted, dismissing the unknown out of hand, having important research materials destroyed, tedious tasks, giving up without thinking through difficult problems.
