Just Another Ghostly Story

Kyokan

"Yo you, you're finally awake!"
Mizuki opens her eyes to find herself sinking into his shoulder. Daisuke's carrying her on his back through the woods. She notices his shoulder wet with something, at the same time something is dripping from her mouth, it's her saliva.
"WAAHHH?!! LET ME DOWN! LET ME DOWN!!!"
"Okay okay I got it! Hahaha, I don't mind carrying you all the way home though" Daisuke just chuckles at her reaction.
"Waaa- that's not the problem here!!" She responds as her face is flushing red from embarrassment. To drool like that on some guy's shoulder.
"Well it's good that you're lively again. This one is a new record really, it hasn't even been an hour yet since you pass out"
He sees Mizuki still gathering her strength to stand back up and holds out his hand to which she just rebels against
"I'm fine. Hmph! Your way of explaining thing is so misleading, you told me it wouldn't hurt my physical body but you never told me it would still hurt! I would've gotten the ghost if it wasn't for that"
A bit pouting. Though it seems her reaction just further entertains him instead of making him feel guilty.
"Well that's what you get for getting in over your head, I warned you not to fight it. Obviously losing a hand would hurt you, you don't need to master Reichitsu to figure that out" he mocks.
"But you lost your hand too back then! You seemed just fin- was that actually painful the whole time?"
Mizuki stops being agitated and genuinely got curious instead to which he only answers with a silent smile.
"Well your technique was wrong too so that's part of the reason why you have to went through all that" feeling that she's getting lectured, Mizuki tries to defend herself
"W-Well that's natural! That was my first time!"
"And that's why I warned you."
"Guuhh..."
Daisuke repeats his statement, this time just a tad more stern. Feeling a bit guilty this time, although still laughing it off, she tries to steer the conversation away from her blunder
"Anyway.., what do you mean my technique was wrong? Could I have avoided the pain if I did it right?"
Following along with her change of topic, Daisuke took the opportunity to teach her some more about
"Reitai. A spiritual body replacing your physical body with the benefit of spiritual matter and properties. However, a spiritual body is still a body, and a body is dead without the organs in it. Just like your brain, your other organs still functions in the spiritual body along with the nerves and veins tied to it. When you create a shape using your Reichitsu while your body is incomplete, it treats the process as another part of creating the body, channeling the organs and nerves alongside those new shapes like a body of water filling in a new empty space. Effectively, you just extend a part of your body, with all it's sensitivity still intact"
Huh...? I don't get all that but, that's just ridiculous. Why would the Reitai still need human organs anyway?"
"Well that's..." Before he can continue explaining, he sees something ahead of them
"...a topic for another day, we're already here"
He gestures towards an old wooden hut in the middle of the woods, an artifact of an abandoned newsstands at an out of commission bus stop. An old man stands behind the counter, greeting them with a smile, though both his eyes are covered in bandages and yet he somehow "sees" them coming.

"Yo oldie, I got something for you"
Daisuke greets casually. Apparently he's acquainted with this shop owner in the middle of nowhere.
"Oh what have we 'ere? an apprentice of yer?"
" Nope, just a client I bring along from another case. For now it'll be safer to have her close by. Mizuki, this here is Oldie. Oldie, Mizuki"
"N-nice to meet you, O-oldie san..!" Mizuki a bit impromptu.
"Oyh oyh, yer the only one who call me that, and same 'ere, young lady. Feel free to browse the store"

As Daisuke's discussing the price of his hunt, the ghost they'd fought earlier in school, with the old man, Mizuki is looking around the store. Various oddities and bizarre items are on display, each stranger than the last one. Dried up body parts, frozen small critters, jarred organs, some suspicious liquids in bottles and vials, all the crazy stuff you'd find in either  a witch's house or a mad scientist's lab or a weird combination of both. She saw Daisuke handing a small glass bottle to the old man. Inside it, a familiar although tiny spectral being caught her eye
"That's... from earlier...?"
