Ch 1.1 and 1.2 are just character intro (including a half-year time skip) towards a 'magic aptitude test' basically.
Basically there' 6 types:
Fire Wind Water Ice Earth Lightning
Water and Ice have some similarity, but the way the teacher explain is that "the simplest way of differentiating them is whether initially the magic come out as ice or water"
So everyone do their test, all causing some elemental phenomenon around them (shoot lightning, wind, etc)
Then Nanali's turn.
Nothing happened in her palm.
Then a girl who hate her gut pointed at her and screamed "Your hair!"
She grabbed her hair, it's light blue.
MC: !?!?!?!!?
Teacher: Oh, well, since magic resides in your blood, something like this does happens on a rare occasion
MC: Wait, I can't cancel this!?
Teacher: NOPE
MC WHAT THE HELL IS MY MAGIC TYPE!? BEAUTIFICATION TYPE!?
Then the room's temperature dropped.
Some thing falling down, and someone grabbed one and muttered "it's ice crystal, how pretty"
Teach: So you're Ice type. Which makes you the only one among this class. I don't know about the other classes, but as expected they're the minority huh"
So there you go, in case anyone wonder if the girl with light blue hair on the cover is our heroine or not, it is her.
Also there's a 2 years time skip right after that :v
