Love it or hate it, there's no denying that ASMR is a cultural phenomenon that's here to stay. I personally listen to it sometimes, though I find there's a very fine line between relaxing and uncomfortable, so I'm fairly picky about which videos I watch, lol. (Maybe this is a common experience?
)
Anyway, one trend I've been noticing is fandom-themed ASMR, where the ASMRtist will dress up as a character from popular media and do ASMR in-character. I think it's a fun idea, and certainly appealing to people who are really into a particular fandom/character. That being said, sometimes I see the character they decide to roleplay as, and I can't help but think... would that character really be very relaxing...?
And of course my next thought was, I wonder which of my characters would make good ASMR? I feel like Green actually would listen to ASMR, and would be pretty good at it if she decided to try her hand at it. Rikou could be a fun unintentional one, just her sitting in her library and reading to you. Most of the other characters, though... nope, I can't see it. 
So what about your characters? Would they be a masterful ASMRtist, or is the thought of them whispering in your ear unbelievably cursed?
