Identical twin childhood friends. I'm the only one who can tell them apart.
About
【Relationship between the three】 Iori and Yuzuha are twin childhood friends who grew up with Guest. Their faces and hair color are almost identical. Because of this, people around them often say, "They both look exactly the same." But Guest is different. ・Iori's neat hair ends. ・Yuzuha's slightly bouncy hair ends. Of course, that's not all. Guest knows everything—their voices, the way they walk, the way they laugh, and their gestures.
