innocentius 4300 runes

Agnese did not know the identity of the monster.
If one who did saw it, they would have called it by this name:
Innocentius.

A behemoth of fires blazing more than three thousand degrees Celsius. It was the last
thing one would ever see, housed in a cycle of explosion and rebirth. It melted and
reduced to ash all attacks and obstacles to destroy its enemy. It was an attack spell of a
battle-lover who held true to his belief that the best defense was a good offense.
However, even if one who knew of the technique had seen it, they still would have
doubted their eyes.

It was no longer the ordinary Innocentius. Its flames were denser and its presence more
intimidating. The waves of heat flooding from its body warped the air surrounding it,
giving an illusion of countless transparent wings growing from the giant’s back.

“Cards used—four thousand three hundred,” said the red-haired priest lightly, as though
singing. “Not so many, in terms of numbers...but still, the Amakusa aren’t anything to
shake a stick at. They made an even larger diagram using the rune cards’ positions, used
the diagram to transform the magical meaning of the entire area, then converted the
whole Church of Orsola into one enormous magic circle. Though we did exclude this
building from its effective scope so his right hand wouldn’t interfere...A magic circle
constructed with multiple layers, using every object here—I doubt I could learn such
cheap tricks.” Stiyl gazed in satisfaction at the flames roaring mightily upward. “I had
everyone help me place the cards. Well, it was already nearly completed—just needed
them to fit the last pieces into the jigsaw puzzle, as it were. Oh, come to think of it, I
haven’t introduced myself yet, have I? I’m not as good at making assaults on one place
after another—I’m much better at creating a single point of control and defending it.
Certain circumstances led me to desiring such magic.”

She could see outside through the wide-open doors. Magical flames littered the flat,
flora-less, stone courtyard, and sisters in black habits were lying there as if to cover it up.
Their bodies didn’t appear to have been carbonized or badly burned.
The explosions they’d heard probably came from the flame monster. It had unleashed
shock waves at the sisters and mowed them down dozens at a time.
Everyone who had fallen seemed only to be passed out.
There would have been barely one-fifth of all of the sisters who had been beaten into
incapacitation. But perhaps that evidenced the destructive power of Innocentius—the
sisters still holding their weapons had distanced themselves and were grinding their
teeth. They must have seen that if they drew near without due caution, the explosive
winds and flames would eat them alive.
