Yuya's tweet states that Sami passed after an accident
accidental drowning (Edit: no clue where I got drowning from. My mistake.). A wake and funeral for his family and friends has already been held.
Sami (沙美) was most well known for his stint as CindyKate's drummer, but he was a multi-talented musician who also sang and played guitar/bass. He acted as a support musician for tons of bands and sessions over the years, and was set to act as support drummer for session band FLAMINGO (フラミンゴ) on August 30.
