They are known as the Shortest Line because they both are the shortest members of the group.
Despite being the same age, Hitomi often speaks in honorific language towards Nako in Japanese and Korean, since Nako started as a child actress in Japan. They are often split up in team competitions, so they are often reminded to speak in half-speech.
Hitomi is better at written Korean than Nako, whereas Nako is better at spoken Korean.
Hitomi has tested at level 5 of TOEIK test, but the test doesn't account for spoken language ability.
Hitomi also gained Korean driver's license, while Nako hasn't.
Both are from the 48 sister group, but never became centers untill 2022, when IZ*One disbanded.
