Of course, the reason he dared to do this was because he had a certain level of confidence. Yang Xiao had already helped him figure out the Water Ghost's method of murder. With his skills, as long as he was cautious, there shouldn't be any major issues.
Besides, he wasn't the only one holding the fort here; Sakai Misaki was also with him.
"Mr. Katou, you...you listen..." Sakai Misaki, who had just sat up from the bed, looked pale, her entire body trembling violently, as if she had been terribly frightened.
"Plop."
"Plop."
"Plop."
Kato Shinjiro also heard it, a series of dull sounds echoed from outside the door, coming from the direction of the emergency staircase, as if someone was stepping in water, and that person was coming upstairs.
Unlike Sakai Misaki's panic, upon hearing the slightly muffled sound of steps in the water, Kato Shinjiro felt somewhat relaxed. It was indeed the Water Ghost; what he feared most was the arrival of an unfamiliar ghost.
