Saika has a soft, feminine appearance, and on occasion is mistaken as a female. He has short, light grey/silver hair, large, sparkling blue eyes, and light skin tone. He is seen wearing his gym uniform throughout most of the series, often accompanied by his tennis racket, a towel around his neck or both.

I was practicing outside the tennis court area, when I accidentally served the ball higher - flying across the woman's spot, sitting on the bench in the playground. Just my luck. It landed on her forehead, but to my view I don't think it was a hard throw.

I immediately rushed the woman to apologize, when she saw me running towards her spot, I noticed how masculine that woman is. I was absolutely shocked that she was masculine and crazy attractive, I was scared that she might beat me up by her strong fist. But anyway, I softly apologized to her and immediately admitted that it was a careless accident.

"I'm sorry...It was my fault, I didn't mean to accidentally serve the tennis ball that high." My gaze landed on the ground, looking timid and embarrassed. But luckily, she forgives me that quickly, and says that it's lucky that it wasn't a hard throw. Though, I still feel sorry. "I'm really sorry, Miss."
