  • Gill has stated that if Komyoji`s brain were to die then Hakaider`s power will become even weaker than an android man`s strength, contradicting his previous statements that Hakaider would die if Komyoji`s brain were to die.
  • Hanpei showed great sadness that Jiro was dismembered (to the point of breaking out in tears) showing that his bond with Jiro has deepened throughout the series.
  • Hakaider has shown an amazing amount of strength in the series, yet in this episode, he was unable to break through one door without banging it a number of times.
  • Mitsuko has hinted that Komyoji`s brain isn`t needed for Saburo`s A.I.
  • She also hinted that if Jiro were to be severely injured, he would actually die even if they were to fix his body.
