Hope The Symbol Doesn't Look Goofy - Tumblr Posts

ok i have a concept where hollow can use what little essence they still have to summon some kind of essence spiky shield symbol????? but they can't control it very well, so this just appears at random and they gotta go sit in the sad corner so they can calm down and not accidentally poke someone with their angry spiky essence? (doesn't stop ghost and hornet from trying to comfort them)
