I learned of his passing after his mother replied to a comment I made on one of his videos on YouTube:
Before he left, though, Adazai decided to give us and the boards a silent, yet powerful farewell:
Adazai was a great member of the TTV community and will be more than missed. He was a fantastic LDD moccist and an exceedingly nice guy.
My condolences go out to his family and loved ones through this most saddening time.
