Guess who changed their name but is forever going to the beach?
IT'S COCONA!!!
It's tanned AV gyaru, Cocona (on the right). Well formerly known as Cocona, she recently changed her name from Cocona to Serina. In addition, she has a new blog. She wants everyone to continue to support her. You can't really hate her since she's a total angel. One that loves going to the beach (even though all the beaches in Japan except the ones in Okinawa are dirty). She also gets into the spirit of the summer season and wears a cool yukata.
