Sharingan

"Shop owner, do you have unique eyes here," Orochimaru asked.

"Like?"

"Red eyes, Sharingan."

Lou look at him seeing he trying to see his capabilities trying to check his ability, but he was surprised that Lou left the counter and come back holding a box full of glass tubes.

Pulling one by one, Lou carefully arranges everything on the top of the counter.

"From Lowes to highest, One Tomoe Sharingan, Two Tomoe Sharingan, Three Tomoe Sharingan, Mangekyou Sharingan, and the Eternal Mangekyou Sharingan."

Orochimaru could flicks his tongue back and forth then look at Lou.

"Mangekyou Sharingan is almost extinct but I did not expect that there are five available in this shop, and what is this Eternal Mangekyou Sharingan and what's different from the two?"

"The Sharingan can be evolved into the Mangekyo Sharingan by experiencing the trauma of loss, granting unique, user-specific jutsu in addition to the Sharingan's standard abilities. Awakening the Mangekyo Sharingan will automatically fully mature a Sharingan if it isn't already."

"Use of the Mangekyo Sharingan causes blindness over time, but this can be negated by transplanting another pair of Mangekyo Sharingan from a close relative, such as a sibling, to acquire "eternal" Mangekyō that never lose their sight."

"Hoho~ a blindness side effect, I did not expect that, is there any other cure besides another eye to remove the side effect?"

"No, but you can buy some miraculous medicine to cure the blindness but I don't know if it will work."

"But you said your item can cure anything?" Kabuto said.

"That's right, but this pair of eyes is different, using it is like using your own life force, what you lose will never go back that's why I don't know if the side effect can remove."

Lou looked at them then shrugged his shoulder," Besides I never try that's why I don't know."

"So if I want a perfect Sharingan, what should I get is Eternal Mangekyou Sharingan"

"That's right."

"... By the way, are you not scared if someone suddenly knocked on your door in the middle of the night because of this?" Orochimaru watches Lou's reaction, he wants to see what kind of reaction he will show.

Orochimaru is testing him.

"You know, there are only two things that can knock on my door, that a ghost or a customer."

"And of it's a ghost?" Orochimaru starts to show a dangerous glint.

"Send to the underworld, ghost should not lingerie in this world."

".... Amazing, I'm starting to feel interested in you..."

"So are you going to buy or what?"

"How much." Orochimaru picks the lowest and then the highest.

"The lowest is only one million gold coins, while the highest is a hundred billion gold coins."

The two sidekicks behind Orochimaru can't help but to gasp after hearing the price, they never see a million much more than a hundred billion.

"So pricey, is there any way to get it besides gold coin?"

"A trade is good."

"Ninjitsu, Scroll, Artifacts, tell me what you need."

"Sword of Kusanagi for one Mangekyo Sharingan."

"I can do that but."

"But?"

".... But you need to survive for a night first." Orochimaru waves his hand taking his sidekick with him leaving.

After the door closed, Lou feel people start to gather around his store and they are started to increase in number too.

"Root or Anbu?"
