Cain had obviously noticed Vale's reaction to his preparation… To be honest, he was prepared to cancel his Spell the moment Vale made his move.
However, contrary to his expectations, Vale allowed him to finish with his Enchantments, and he even seemed amused by the Beasts he summoned!
'Tsk… He's underestimating me…' Cain silently thought.
Well, he was right…
During Vale's third year in the Academy, he had a subject called Twelve Arcane Paths that allowed them to study the other paths to their introductory level.
Vale could somehow recall that Beast Arts could summon the powers of mythical beasts in another realm… This was why he was a bit curious and wary about his opponent.
After all, he had no idea which Mythical Beasts could Cain summon. He may have to adjust his abilities depending on which Mythical Beast it was.
