Niji, the second optimist of everyone! Well, that's a bit of a lie. They have that persona of a cheerful person, but in reality are actually really mean and envious of others. They think they are better than others and that they should be the 'leader' of everyone. Even though the group doesn't really mean if there is a leader or not, the group just wants everyone to be happy, and that makes Niji a bit... mad. Niji wants everyone to feel inferior than them, but is instead recieved with love and admiration, not envy at all! Niji's type of singing is a cute and happy type of song.
