“Keaaaaaa!!”

Along with that shrill war cry, Raios swung his sword straight down.

“Seyaa!!”

With that short scream, Kirito slashed diagonally upwards with his
sword.

The two swords clashed as the red and green grappled with each
other, the resulting impact made the floorboards tremor while the
glass windows cracked and broke towards the outside. As he stared
at the black and silver blades struggling where they collided, Eugeo
finally understood why Kirito did not use the Aincrad-style.
