Five Avex actors, including Ryoko Nagae and moca (lol), have been confirmed to appear in the musical “Kokoronokakera”! The main visual of Nagae and former Takarazuka top star Kei Takashiro has also been released!

Performance information for the musical “Kokoronokakera,” which will be performed at Hakuhinkan Theater in Tokyo from September 25th, was announced on the 24th of this month.
This time, five actors affiliated with Avex, including Ryoki Nagae, have shared their aspirations and enthusiasm for the work.

This work is produced by T1project, a company that aims to “produce actors who can express humanity and screenwriters and directors who can master the human condition.”
“Is forgetting memories a happy or unhappy thing? This is an emotional story that explores “personal identity” and “memory” with the rebirth of a family as its central theme.”

This film features five Avex actors: Nagae Ryoki, moca(lol), Sekine Yuna, Uchida Wataru, and Nakayama Yuki.

The lead role will be played by Ryoki Nagae, who starred in the stage “Hetalia” series and is active in various popular productions, including the stage production “Aoyama Operetta.”
Nagae commented, “I’ll be meeting some familiar friends and some new people. I’m excited about what will be a fresh experience.”
He continued, “I look forward to enjoying the warmth and sharpness of the work, and will work hard with the cast and staff to achieve it. I hope everyone will come to the theater to see it!”

Moca, a member of lol who has expanded her range of activities mainly to stage productions, will be appearing in her first musical.
“I am very excited about this challenge. I will tackle the role head on and do my best to show a new side of myself through the stage,” moca said, expressing her enthusiasm.

Sekine, who is known for her starring role in the “Shin Sakura Wars the Stage” series and has extensive musical experience, expressed her joy at being in this production, saying, “I’m very happy to be able to perform on the stage of my favorite musical! When I read the script, the feelings of each character and the lyrics of the songs were portrayed so directly, and it really struck me. I’m really looking forward to performing in it!”

Uchida Wataru, who joined the theater company 4 Dollars 50 Cents in 2010 and is currently expanding his range of activities in stage productions and dramas despite his short career, commented with a fresh air, “There are so many wonderful seniors around, so I will absorb a lot of things and do my best to create a production that the audience can enjoy!”

Also, Nakayama Yuki, who gained popularity in the stage production “Osomatsu-san on STAGE ~SIX MENS SHOW TIME~” and played the lead role in the stage production “From Eroica With Love”, will be playing an important role.
Nakayama was enthusiastic, saying, “We have a large cast and it’s a full-fledged musical, so the entire company will work together to create a production that will make everyone feel something through both the music and the acting.”

The main visual released this time features Ryoko Nagae and former Takarazuka top star Kei Takashiro. Kei Takashiro has the glamour of her Takarazuka days, as well as the beauty and acting ability of an actress.
Takashiro commented, “I’m nervous as it’s my first time meeting Hakuhinkan Theater, the cast and staff, and everyone else. I would like to bring the role to life while cherishing the subtleties of the heart. I’m looking forward to seeing you at the theater.”

This production brings together talented performers, from promising young performers to veterans of the musical industry.
It’s an exciting production and I can’t wait for the performance in September.
