"Finally all of you have arrived dear heroes" I exclaimed in a very threatening tone
"Selene right?"
"Wrong actually I made up that name actually my real name is kaguya astaroth"
"A-astaroth? Y-you are the p-princess of this kingdom"
"Exactly but honestly outside the kingdom I don't like being called princess so call me whatever you all want"
"Are you sure?"
"Exactly and avoid the formalities too"
"O-ok"
"Hey kaguya are they the heroes you told us about?"
"They seem weak enough to be Heroes"
"How bad you are Miya but you're kind of right"
"Miya Zan Anna shut up"
"O-ok"
"They are my adventure companions, now introduce yourselves, you heroes"
"I-I'm Sang we met 3 years ago"
"Oh I remember you"
"I am yora"
"My name is Zelius"
"My Name is Violet"
"Seiya"
"Crimson"
"Lure"
"Zesha"
"Xuan"
"Nora"
"Ignis"
"Black"
"Helio"
"Mh, I understand well, first of all I will give everyone some tests"
"Tests? Seriously?"
"don't worry, there are some questions and then we will move on to a practical phase"
"oh ok" almost everyone exclaimed doubtfully
"I see there are some elves among you so these questions will be easy for them, first question how does mana work?"
I saw a hand raised
"I, I"
"Ok Yora so what is the answer?"
"There are two types of mana, the corporeal one and the natural one, the corporeal one works with a sort of nucleus that is present in our body and prevents the mana from dispersing and is only released with a command or other and is finished, while the natural one we can find it everywhere and it always regenerates so it's infinite"
"Correct but at the same time a bit wrong" "Eh! why?"
"Let me explain first of all yes the bodily mana is finite and to use it you don't need a command but a signal this signal allows us to use the bodily mana by doing this we take the magical substance present in our body and transform it in this case thanks to a command, the power varies from the amount of mana you use and if you use a spell without speaking it will be stronger" "Mh I understand"
"Well now they continue" and so at least 2 hours pass as if nothing had happened
