My apologies for the lack of updates last week. I was either encountering website problems (as long as this website is having an issue I don't update) or dealing with exhaustion.

That is indeed Ryohei. He was sorted after Kyoko.

Kyoko, blessed Kyoko, took pity on her and answered the question. "Yin and Yang is the concept of Duality, that one cannot exist without the other. The world is in balance," Kyoko said.

"What does that mean?" Daphne Greengrass asked. "And how does that related to how Aqua Eructo is a Dark Spell and Avada Kedavra is a Light Spell?"

"Well, Miss Greengrass," Ayame said. "Here's an example for you. There is a shadow on the ground. What is causing the shadow?"

"A light on an object?" Daphne answered her.

"Yes. Would there be a shadow without the light?"

"No."

"And if all you see is a shadow on the ground, what does that tell you?" Ayame asked.

"That there is a light source somewhere?" Daphne asked.

Ayame nodded. "The concept of Yin and Yang is the idea of two opposing forces that are actually complementary. Light and dark, fire and water, life and death, day and night. They are dependent on each other, you cannot have one without the other," Ayame explained. She waved her wand, displaying a picture of a circle in the air. Half the circle was colored black with a white dot in it, the other half was white with a black dot in it.

"This symbol is called a Taijtu. The black side is Yin; the white side is Yang. You cannot have Yin without Yang, cannot have Yang without Yin. To summarize, Yin is the shady side. Some characteristics of yin are dark, female, moon, cold, decreasing, water. Yang is the sunny side. Some characteristics of yang are light, male, sun, warm, increasing, fire," Ayame paused, looking at her students.

"Aqua Eructo is a Yin Spell or a 'dark' spell because water is a Yin characteristic. Avada Kedavra is a Yang spell or a 'light' spell because the signature green light that the killing curse is known for is a Yang characteristic," Ayame explained. "In fact, your gender alone already has you leaning towards one way or the other. Your personality is another. I'm willing to bet most of the girls were the ones who successfully performed Aqua Eructo before the boys."

Silence.

More silence.

Ayame fretted just a little, though outwardly she didn't betray her nervousness. The Wizarding World located in Europe was not a place most supernatural people were fond of. Their arrogant superiority, blindness regarding other creatures, blatant ignorance for the most basic concepts, including Yin and Yang made most people swear off traveling anywhere near there.

And here she was shattering the worldview of these students. Was it too much? She hadn't even cover the concept of Wuji or Trinity!

Thankfully her kids didn't look like their worldview was turned upside down. (Because, well, she taught them this already. It wasn't anything new for them.)

"Look, the point here," Ayame said, once the silence had continued on for too long, "is that you cannot assume that just because something is 'Light' that it is good nor can you assume that something that is 'Dark' is evil. Light and Dark are simple things that just are. I'm here to teach you how to defend yourself."

"Any questions?"

And that brings Lesson 1 to an end. I can totally admit that I started this fic because I wanted to geek out about my world building notes. -ninja-

See Chapter 6 of Goddamn Namimori for World Building Notes about Spirit Energy. See Chapter 12 of We Weren't Born to Follow for more information about Dying Will Flames/Spirit Energy/Yin and Yang in context.

If you haven't gotten a chance yet, WWBtF updated this past Friday. -cheers- Go read it!
