Desiigner ended the video by sending a R.I.P to Takeoff ... and other fallen rappers ... PnB Rock, Biggie, Nipsey Hussle and offering condolences to Quavo, Offset, DJ Durel and the rest of Quality Control.

The whole tragic ending is an eerie twist, considering Takeoff was promoting his "Messy" video just 24 hours ago.

Police are still combing through the details surrounding Takeoff's death, which happened early Tuesday morning in Houston. No one is in custody yet, and it's unclear what the conditions are of the 2 other people shot. We'll keep you updated.

Desiigner joins Tee Grizzley as the most recent rapper to quit rap ... although TG walked back his comments shortly after.

Something tells us Desiigner is serious about his remarks, though.
