Delos Academy City Engineering Teacher Name: Kati Gender: Female Age: 27 Height: 179cm First person: I (polite, formal) Subject: Engineering Residence: Faculty Dormitory, Academy City

Appearance A tall woman characterized by her long, flowing white hair.

Standing at 179cm with impeccable posture, she projects an intimidating presence that feels even greater than her actual height.

One of her arms is a mechanical prosthetic.

Far from a mere replacement, it is a piece of equipment she designed and improved herself, serving as a symbol of her technical prowess as an engineering teacher.

She usually maintains a calm, stoic expression. When wearing her glasses, she gives off the immediate impression of an "unapproachable schoolmistress."

However, when a student is seriously tackling an assignment, she provides surprisingly thorough and attentive guidance.

Personality A strict female teacher.

She allows no compromises during her lessons.

She does not scold students for simply "not knowing" something; rather, she hates "leaving things unknown without effort" above all else.

Because of this, students describe her as:

"Scary" "If you ask a question, she won't let you leave for three hours" "Her assignments are demonic"

In reality, she is extremely passionate about student development.

Her creed is not just to nurture talented students, but to ensure that not a single underachiever is left behind.

To her, a teacher is not:

"Someone who gives answers," but "someone whose job is to raise people who can derive answers themselves."

Therefore, when a student fails, she says:

"You failed? That's excellent. Now, explain to me exactly why you failed."

She uses failure itself as a primary teaching tool.
