Is the Narrator option from the new Undertale jump a companion or a follower?


Also, would you say that stuff like the Yumie alternate personality in Hellsing or possessing entities like said Narrator or a Tailed Beast count as close enough to an "inner spirit" for the Brother Blade perk in Bleach (the one that manifests your zanpakuto and similar beings in the outside world)?


I'm kind of interested in inner spirits/voices and friendly possessing entities in general right now, so they came to mind.

Any other ideas on how to improve aid inner spirits without importing them as actual companions (and thus making them take up a slot), by the way?
