The trend of top Japanese entertainment stars diving into music is heating up like never before. No longer just dabbling in fashion or social media like Suzumori Remu or Sakura Momo, many artists are seriously pursuing professional singing careers.

Following the success of Kawakita Saika (stage name Mimei), the famous close friends Ishikawa Mio and Kasui Jun have finally made their music dream a reality by forming an idol group and releasing their debut MV today, January 20.

The close bond between Ishikawa Mio and Kasui Jun has long been celebrated by fans. They’re not just colleagues but true best friends in real life, often traveling together from Ishigaki Island to South Korea. This deep connection laid the perfect foundation for their group, named Dopamine.

The group’s formation was announced right after their live performance in Tokyo on January 18. The name “Dopamine” reflects the happiness and excitement they want their energetic music style to convey.

True to their promise, Dopamine dropped their debut MV titled Backlog Game Boy (バックログ・ゲーム・ボーイ) on their official YouTube channel on the evening of January 20. This marks a major transformation for the two actresses into full-fledged music idols.
The MV perfectly showcases their combined strengths: Kasui Jun’s proven vocal skills from previous cover videos and Ishikawa Mio’s captivating visuals and stage presence.


The MV has already received enthusiastic support from fans. Their decision to debut together is not only a strategic career move but also a heartfelt gift to those who have followed their friendship.

With their existing fame and impressive musical talent, Dopamine is expected to become one of the most promising idol groups soon. Their January 20 MV release is just the beginning of an exciting musical journey for this beloved duo.
