Hilia is studying.
Studying a unique magic.
This magic is completely incomprehensible to Hilia; it seems to be a composite magic fused from many elements.
It's very complex, but Rose says even a Tier One Mage can learn it.
It's not much related to the rank, but significantly related to personal learning ability and elemental affinity.
Thankfully, it doesn't include space elements, which Hilia is least adept at.
According to Rose, the effect of this magic, once cast, can disintegrate demons over a massive area, but it is only effective against demons with specific characteristics; it is ineffective against others.
In other words, this was taught to her by Rose specifically to solve the crisis of the beast tide.
