He could barely stifle a shocked laughed when the girl on the diving board literally jumped in surprise at his voice. Damn, that was a hell of a way to make a first impression, though. He couldn't help but watch as she moved to the edge of the pool and climbed out, more out of concern that she'd end up drowning in the shock than out of lust. He was too winded to think about anything other than relaxing and cooling his body down a bit. His body was flushed with blood from his workout, and the pool was a good way to cool down, both literally and figuratively. While the girl he'd startled was coming out of the pool, Isamu bent down and touched the water with his hand. 

"Hello water, my sweet. Your lobster has returned to you." Whispering so that the girl couldn't hear him, he derisively shook his head and held back his laughter yet again. The malformation of his hands was rarely actually a disability. At worst, it was an inconvenience that he had primarily already overcome. The Yamaku Lobster came to terms with himself long, long before arriving at this school. 

When she finally addressed him, Isamu smirked in realization. [i]Blindness. Helps explain why she didn't notice me.[/i] "Ah, that's quite alright, it's my fault for calling out to you while you were on the diving board and clearly focusing." He wasn't just being polite, either. He really had been genuinely concerned, despite the laughter he had to hold back. Being at a school like Yamaku made one a bit more insightful on the frailty of life, though Isamu could only call upon second-hand experiences on this matter.

"Well, Mizukimura-san, it's nice to meet somebody with such poise. I am Tanaka Isamu, and I'm a third year student here." He couldn't blame the girl for her apparent shyness at addressing a male student while in a swimsuit. And if she knew who she was talking to, she'd [u]definitely[/u] be self-conscious. One of the few things he regretted about his time at Yamaku was the reputation he'd built for himself. It was embarrassing, frankly. Though, he tried not to let the rumors get to his head. Even if they were true. Almost every one of them. 

[i]Not working, Tanaka! Distract yourself! Quantum mechanics! Beta-plus decay! Manami-chan! NO, ABORT, ABORT ABORT![/i] Stepping into the pool to shock himself out of dangerous thoughts, Isamu sighed as the cool water covered his aching body. Few things beat the feel of this. "So, Mizukimura-san, what brings you out here? Business or pleasure?"
