Two days went by after Pledis Entertainment revealed their third and fourth members for their newest girl group, Luminous, and unexpectedly we now have another member to reveal for the final lineup! To add to the supposed seven member group, we have the official fifth member of Luminous, Kim Inyoung, or as known by her stage name, Erin.

Erin is our first triple threat to add to the group of ladies and she definitely stands up to this title. With being the lead dancer, a rapper and vocalist, this seventeen-year-old maknae is racking in the points for her outstanding brilliant talent. Yes, you read that correctly, this adorable and skilled girl is the maknae of Luminous! Just like that of her labelmate, Seventeen's powerful maknae Dino, she is more than just her age and can stand up against the big boys! She might have a lot to fall on her shoulders, but she seemed to be taking her responsibilities very seriously. However, there might be something else that catches your eye besides this members popping and locking. No, this isn't just deja vu- Erin might look exactly like popular idol group BTS's leader and rapper, but that's because she happens to be Rap Monster's younger sister! So talent does run in the Kim family after all! Besides being the next big idol sibling duo, this little maknae isn't just stopping there and plans on standing out from the huge shadow of her older brother to show the world the powerful abilities she has as a member of Luminous. There's no way you can even compare the two once you watch her solo vocal performance video posted by Pledis on their Youtube channel as well as Twitter. 

However, despite her amazing floor work, seemingly-flawless ability to freestyle dance, and her on-point rhythm, Erin is more than just her dancing. With the sweet lit to her singing voice and a precious yet apparent swagger to her rap, this little cutey isn't someone to look past. We can't wait to see more from Erin and Luminous. 

Be sure to check out Erin's profile and solo videos below. We'll be anticipating the reveals of
