The next moment.
Ryōken appeared before Tsuki Uchiha and swung his sword.
"Steel Flash!"
A force capable of cleaving gold and iron abruptly erupted. Sword Pressure spread through the air as the blade's gleam flickered and pulsed.
At the same time, Tsuki Uchiha's ninja sword had nearly finished gathering power. Without a second thought, he activated it and launched his attack.
The ninja sword actually flew from his hand. As it shot forward, it exploded apart with a thunderous crash, becoming a dazzling beam of light that streaked ahead.
Wherever it passed, the air melted and the gale fell still.
Vast chakra fluctuations swept wildly outward.
Ryōken's gaze narrowed slightly. Even he had to take notice of the power behind this strike, which had nearly sacrificed the ninja sword in an explosion.
Given enough time, this costly attack might have unleashed power approaching that of an S-rank ultimate ninjutsu.
Fortunately, it had been unleashed in haste, before the technique could be fully activated.
Still, there was no time to change moves, nor was there any need to. Ryōken was extremely confident in the power of Steel Flash.
A multiplied increase in force was no empty claim.
It might not be enough to kill Tsuki Uchiha in a single strike, but blocking this move would not be a problem at all.
Gripping his sword in one hand, he struck the beam with a precise slash.
Screech, screech, screech!
Pale cyan sword light and unparalleled force burst forth, rapidly wearing down the beam's power.
With a cold snort, Ryōken exerted force through his hand and slashed straight through it.
The dazzling beam immediately split in two and gradually dissipated into the air.
Just then, Ryōken's heart suddenly clenched, as though some invisible entity had fiercely seized it. An intense sense of danger
