nonowa
A stylized depiction of Amami Haruka with her face formed by the characters ののワ (hiragana no no and katakana wa = nonowa). Sort of like this:
の の
ワ
or this:
のヮの
When she appears together with the regular Haruka, it might be a case of dual persona.
Not to be confused with awesome face, despite the resemblance.
