During class, Makoto hears her cat meowing over the school’s intercom. After retrieving her cat, Makoto is confronted by another student. The student, also a witch, verbally reprimands Makoto over the ordeal. A few minutes into their conversation, Makoto asks the girl a question.

真琴(まこと):
「あの~ 今更(いまさら)なんですがお名前(なまえ)は…」
“Um... It's a bit late for this, but what's your name?”

In this situation, 今更(いまさら) is being used politely, without a negative tone.
