speeding jet jump

The rescue plane was not so much flying through the air as it was traveling with its
propellers like a hovercraft. The craft shot just above the ground at high speed like a
bullet and flew right past the mass of knights.
As it did, a slide door in its side opened.
A figure unhesitatingly jumped from the plane into the middle of the knights.
The rescue plane was traveling at a speed greater than 500 kph.
The trajectory of the person falling from it was more like an impact from the side than a
descent from above.
A normal person would certainly have become a stain on the road surface. In fact, it
wouldn’t have been surprising if it had created a crater with a radius of a few meters.
But this person landed softly in the middle of the enemy lines.
Almost like a feather.
It was not an easy-to-understand battle performance from some sort of military exercise,
but someone with an understanding of a certain level of martial arts would naturally be
able to tell what incredible skill was hidden in all the small movements making up the
phenomenon occurring there. It was that kind of action.
The knights hurriedly drew their swords to face the attacker who had suddenly appeared,
but the figure standing amid them ignored them and glared in Carissa’s direction.
“A Saint, hm?” said Carissa quietly while being glared at. “In that case, the remaining
Amakusa members must be piloting that plane.”
“...We can discuss this afterwards.”
Surrounded by a large number of knights, Kanzaki Kaori reached for the hilt of her
sword.
