When the US promo videos for the R1 MoHS release first came out, they used the word "psychic". By the second video, they were using "ESPer", apparently due to fan feedback. I mention this to (neutrally) point out that some people seem to feel strongly about this.

I forgot what word Haruhi uses for "sliders", but I think it's probably "besekaijin" (again, possibly incorrect romanization), judging from my (Japanese) copy of that Newtype special from way back when. Translates to "different world person", and since "people from another world/dimension" is unwieldy, I can't think of anything better than "slider".

異 is い, so 異世界人 is "isekaijin".
