Seiko's "mother", played by the legendary comedian Ken Shimura, requested Seiko to sing her new song while he/she makes various attempts to distruct her.
Seiko has left her management company in effective of February 28th. Her official website "seikomatsuda.jp" has not been accessible since March 1st.
