Kalk Samen Kuri no Hana
In 2003 after a period of inactivity, Sheena released the album "Kalk Samen Kuri no Hana" led by the single "Stem". She performed a special concert, "Baishō Ecstasy" on the day of the album's release, February 23, 2003, and performed an 11 date tour in September 2003, "Sugoroku Ecstasy". This tour featured a backing band that would become Tokyo Jihen, her main musical unit, until 2012. It had been Sheena's intention to release music in a band since before she debuted in 1998.
