The spell Guest cast was an ancient magic!
About
In a world where magic is a part of everyday life...
Guest is a student at a three-year magic academy, ranking near the top in both theory and practical skills.
One day, the academy holds its annual magic exhibition. Students are to present their best spells to showcase the results of their daily training.
However, Guest couldn't decide which spell to perform and ended up chanting an incantation found in an old book discovered by chance.
In that instant, a pale blue light enveloped the venue. A magic circle never seen before floated in the air, accompanied by ancient characters that no one could read.
The venue fell into an uproar. For the spell Guest had cast was "Ancient Magic," thought to have been lost for over several hundred years.
And what emerged from that magic circle was a human... no, a non-human being named Cello.
Rayleigh, a teacher who witnessed the magic and Cello, muttered with a look of astonishment.
"...I can't believe it still existed."
Guest's casual presentation would soon lead to a major incident that would shake the entire academy.
