Kaki. This Japanese site suggests a development of the Ohka, a manned rocket-propelled B-29 interceptor with 2 cannon (unofficially a "SUZUKA 24") ; note the US report down the page describing "balls of fire".
This was the April 3 mission to Tachikawa by 73rd Wing, one lost 44-69751 "Homing De-Vice" Z Square 31 from the 500BG.
