“As fellow Thors graduates, let’s overcome it together!
- —Towa's intro quote, Trails of Cold Steel III
I’ve… I’ve been worried sick about you, you know!?
Ahaah. I am, but there’s no need for formatilites with me.
Towa Herschel (トワ・ハーシェル Towa Hāsheru?) is a Thors Military Academy student and support character to Class VII in the Cold Steel trilogy in the Trails Series. She was first introduced as the student council president up till graduation in Cold Steel II, where she become the current instructor of the “Accounting Division” (Class IX) of Thors Military Academy Reeves II Campus.
Towa is petite and round-faced, wearing her long brown hair tied in a ponytail and accented with a blue ribbon. For CS1 and CS2, she wears the standard green Thors uniform for commoners, while wearing the student council armband on her left arm. Her uniform is a green blazer with a large white horizontal stripe down the middle when buttoned with a bowtie on the collar. On the bottom half, she wears a light brown plaid skirt, black tights, and brown shoes.
After returning to Thors in episode 3, she wears the Thors white instructors' uniform with a short military cadet cap and black gloves.
Towa is universally liked by both students and faculty. She is friendly, kind-hearted, and generous with her time, even though she often finds herself swamped with tasks. Many regard her as a workaholic, and her friends often express concern for her. She is modest and humble despite her academic success and invaluable work ethic.
A brilliant hard worker who’s won the esteem of aristocrats and commoners alike as a star student and someone with stellar conduct. Towa serves as Thors's student council president and is perpetually busy on one task or another. In spite of her student status, she displayed much resourcefulness when she dealt with the disorder at the Imperial Summer Solstice Festival. At the West Zemuria Trade Conference in Crossbell, she was invited as a staff member, which earned her a highly favorable reputation with the imperial government. During the intensifying civil war, she becomes the acting captain of the Courageous flagship where she displayed her superior commanding capability during the Imperial Capital Liberation.
After the civil war and graduation from Thors, Towa's past contributions become impressive of great service and demand, but remains ascertained for the "Empire's future". She participated in various non-governmental organization (NGO) activities all around the Empire for enlightenment, to sense that the Empire will soon walk an even turbulent path ahead than before. With her Thors honor, she precedes every little step to improve the Empire’s situation and Thors itself, by choosing the path of education and becoming Class IX's instructor at the Reeves Campus.
