AkaRed is essentially the spirit of all Sentai Reds, except he has a human body and so might ping as some kind of demigod/guardian spirit type...being? But there was a time when there weren't any Super Sentai due to the first 34 teams sacrificing their powers to save their world (thus creating all those Ranger Keys), so he ended up being more mortal and human between then and when the 35th team, the Gokaigers, were formed. And because there weren't any Super Sentai around the time it happened, he actually died died. But then Marvelous returned the Ranger Keys at the end of Gokaiger, so all Super Sentai exists again, meaning that he may have returned to the living. Maybe. Toei hasn't quite confirmed it yet, but this is the general consensus among the toku-borg here in CFUD.

He may also ping oddly beyond the whole dead thing because, as the spirit of all Sentai Reds, he embodies their fighting spirits. Sooo one human(-esque) soul, confirmed dead, with connections to at least 35 other souls.
