It's been revealed that actress Hashimoto Ai participates in Oomori Seiko's new song "Dakyoushi." 

This song will be included in Oomori's upcoming album "Kintsugi" to drop on December 9, and was released digitally on November 25. Hashimoto, who has been Oomori's fan from before, commented, "Oomori-san always makes my dreams come true. Among the people I know, she is the kindest adult. I am just a fan who follows her, but she gave me affection and this outstanding present." 

This is the first time Hashimoto participated in singing in an artist's song. She has previously appeared in the music videos for Oomori's songs "Midnight Seijun Isei Kouyuu" and "Kimi to Eiga." The last time they worked together was about seven years ago when Oomori provided the music and theme song for Hashimoto's starring film 'Wonderful World End.'
