On July 1st, AKB48 Team B member Sato Natsuki celebrated her 21st birthday!

The adorable star wrote on her official blog, "I've safely made it to my 21st birthday! 20 was a year where I grew up all at once, but after turning 21, I'd like to keep improving seriously, little by little." She reaffirmed her desire to keep working hard, saying, "From now on, I'll face myself steadily, I'll treasure myself, and treasure everything around me to the same extent. I'll put all my strength into my college and Korean studies, and work hard to become someone who shines!"
