The effects of steam were not limited to high temperatures. The emergence of large amounts of water vapor also interfered with visibility.
In the area where they were fighting, those outside could only see vague flashes of color or occasional ripples in the steam, enough to confirm that both sides were still engaged.

The only one in trouble was Minato Namikaze. He was a typical speed-type ninja. He possessed neither powerful spiritual strength in sensory abilities nor a broad field of vision, leaving him able to rely only on Uchiha Yū to guide him.

Thinking of a compromise, he instructed Minato Namikaze, "Use Wind Release ninjutsu to break it apart next.
