   The evolution and characteristics of supernova remnants are
   considered to be affected by the circumstellar environment of
   progenitor stars. In particular, wind-blown bubbles created by the
   steller wind of massive stars will have significant effect on
   supernova remnants in that bubbles. Although these remnants are
   difficult to be observed because of their low X-ray brightness and
   the contamination by surrounding HII regions, the Einstein satellite
   detected several supernova remnants in the giant HII regions in the
   Magellanic Clouds. We propose the first hard X-ray spectroscopy of
   supernova remnants clearly associated with the wind-blown super
   bubbles in the Small Magellanic Cloud.
