I for one thinks Akira is dead but some others say he isn't.
Due to the vamps morphing ability people assume that the head the vamp was displaying was false. I am supporting my theory by this. #1 Akira has potential to be an interesting character and he is related to kurono, i dont believe oku would kill him off without developing his character. #2 Akira is a vampire, but he is still human. Some of you may argue against that but if they are not human Gantz would likely have sent the Gantzers after them a long time ago. Because of this he may end up in the system. and reason #3Kurono's brother may end up fighting alongside katou and the rest' tell me who would'nt want to see that? This gives oku the opening to develop Akira's character. Think about it he'll help bring back kurono and he'll fight against some aliens and the other vamps. This is my speculation, if any of you have a different opinions as to why Akira's death is false ill gladly hear you out. no ones a hundred percent right.
