Traditionally, a Japanese surname is written in kanji and placed before the forename. However, when introduced, 'Mirai' was listed first in katakana, making it ambiguous whether 'Mirai' was her forename or surname. There was speculation that her name was written in Western order, as Ring Suzune before her had been, since 'Komachi' is written in Kanji instead which would normally signal such a case. Both "Mirai" and "Komachi" are feminine given names, with neither being a Japanese surname further adding some confusion.
It was later confirmed that "Mirai Komachi" is a nickname for the character and "Mirai" is neither her surname nor her given name.
The name was chosen by combining Mirai (未来), a personal name meaning "future", and Komachi (小町), a personal name which translates to "Beauty" according to BNS. This can be interpreted as "Future Beauty".
