Natsuki Ongaku

Natsuki Ongaku is the fifth member of the main karaoke group, a college sophomore. Natsuki's major is Business. She is 168 cm.

She has a laid back bro-like attitude, and is most certainly the laziest in general. However, she has great talent, possible the highest rank (at the beginning) of the main team. Her father is the principal, Hidoi Ongaku, and she has one younge sibling she is very protective of (even more so when she was in high school).

Her defining song is "Sorairo Days".
