With Mr Wright quickly take a chair from other room and bring it to the dining hall, Azumi took a seat just Alfin and Mahsuri while Aqua happily float around the now Mahsuri seat

""What is ethos and spirit?"" [Ray, Mile]

"Oh mine, someone doesn't know who I am, that's sad" [Aqua]

"Sorry blue hair sis" [Mile]

"It's ok, I am just joking" [Aqua]

"Well, they are still young, so it's understandable" [Lady Air]

"That, and the fact that both spirit and ethos were a mysterious being shrouded with layer upon layer of myth. Even my tribe and the fairy tribe only know so much about Titania" [Filaurel]

"I wonder what Titania is doing right now?" [Aqua]

"Sister?" [Mile]

"In a sense, yeah" [Aqua]

""??"" [Mile, Ray]

"Wait! Where are our manner! It's nice to meet you Lady Mahsuri, I am Princess Alfin Rose and this is..." [Alfin]

"Alfin, there's no need for that" [Azumi]

"Huh?" [Alfin]

"Lady Mahsuri already knew each one of us here" [Azumi]

"As Azumi said" [Aurora]

"But how?" [Alfin]

"That's because I am here from the day Azumi and Aurora meet me, I simply become one with the water molecules in the air and have been observing what have happen so far." [Mahsuri]

"I see" [Alfin]

"Plus, it's nice to see the two boys that I once saved have turned into quite a strong gentleman" [Mahsuri]

"Thank you for saving our lives, Lady Mahsuri" [Duke Hiaccio]

"You are welcome" [Mahsuri]

"Lady Mahsuri, who are you?" [Mile]

"Oh my, we forgot about little Mile question" [Aurora]

"Very well then, I will explain about ethos first, though one person with the high ethos might find it boring" [Aqua]

"No, please continue, as Filaurel have said, ethos, spirit and the gods were shrouded with mystery that there are so much to learn about them" [Mrs Kirthiga]

"Sure enough, those pesky church and their information control" [Azumi]

"Just stop before we are getting side tracked once again" [Duke Hiaccio]

"Alright, here goes" [Aqua]

Ethos, they are the personification of free mana in the world. They are contracted by the human and others not only to enhance their magical power but also to help in various other activities. To do that, the person in question must have some amount of power to contract certain classes of ethos and must be compatible with them. Even with those, ethos can still refuse to do so by their own will.

The royal research institute have once theorised that ethos are simply a lump of mana that were given life by the spirit or by the gods. When asked about that from Alfin, Aqua simply said

"All I can said grossly is it's half correct and half wrong, and since you still haven't got the permission from other spirit, I can't tell you much about it" [Aqua]

"She is right, while the spirit and the highest ethos certainly know and can tell you if they so wanted to, those information can lead to destruction of the world if given in the wrong hand. As such, we spirit will only give those information to the holy hero" [Mahsuri]

"I see..." [Alfin]

"Well, you just have to be a holy hero then Alfin" [Azumi] 

"Said the hero himself, you know it's impossible for me!" [Alfin]

"Oh, we will see about that" [Azumi]

"Can I continue?" [Aqua]

"Please and sorry for the interruption" [Alfin]

"Same here" [Azumi]

Ethos, based on their power and the amount of mana that they have, were classified by human as 

Highest

High

normal

low

very low

Going by those classification, Aqua further explain that the highest ethos are usually chosen by the spirit themselves to have part of their power and will thus take a humanoid form once they have successfully receive those power. Those highest spirit as of now are

Highest fire ethos "Salamander"

Highest water ethos "Aqua"

Highest earth ethos "Dunia"

Highest wind ethos "Sylph"

Highest mirage ethos "Titania"

Highest space ethos "Angkasa"

Highest time ethos "Jikanz"

"And among us ethos, Titania is without the doubt the strongest and oldest, she wasn't only the first ethos to be born, but she herself have fight Ishmelga alongside the holy hero multiple time and survive. Not only that, she is the queen of fairies and also regarded as mini god by the elf" [Aqua]

"Then, how about other ethos from before?" [Blanc]

Blanc questions make Aqua paused for awhile, seeing this, Lydia smack his head for being insensitive

(How should I know that!) [Blanc]

(It's still your fault!) [Lydia]

"It's ok, both of you. As for the answer to that question, none of the previous highest ethos survive" [Aqua]

"I'm sorry" [Blanc]

"It's ok" [Aqua]

With that, Aqua finish her explanation, before Azumi add on one more thing

"Well, she forgot to mention this, but Aqua wasn't contracted to either one of us, she simply help us on her own free will" [Azumi]

"I forgot about that, oh and one more thing" [Aqua]

Aqua look intensely at Azumi

"You really are..." [Aqua]

"?" [Azumi]

"Well, nothing wrong to tell you I guess, I don't know how but there seem to be a neutral highest ethos residing in you" [Aqua]

"Is there such a thing!" [Alfin]

"Why are you the one that is over reacting to it" [Azumi]

"Master?" [Aqua]

"As Aqua said, a highest neutral ethos have never been born simply because there is no neutral spirit, this might be the first one of it kind. Still, it is developing inside of you" [Mahsuri]

"I see, so what should I do?" [Azumi]

"For starters, feel that ethos inside you, and once you do that, give it a name" [Mahsuri]

"Right!" [Azumi]

With that, Azumi concentrate all of his focus and feel an ethos aura inside of him by using Aqua as his reference. After 5 minutes have passed

"!" [Azumi]

"""Did you feel it!!!"""[Mahsuri, Aqua, Alfin]

Azumi simply nodded and with one breath

"Doppelganger!" [Azumi]

With his word, a highest ethos of neutral spirit born into the world. Opposite of her name, this ethos have an opposite characteristics from Azumi. It take the form of female with a long white hair, white attire almost similar to what Azumi always wear and a staff beside her. Her face is the feminine version of Azumi

"Yes, Master?" [Doppelganger]
