Arai Sayaka

Sayaka Arai (新井 纱弥香), named Matsuo (松尾) in the first season of To Love-Ru anime, is a minor character, the classmate of Rito Yuuki in both his first and second year. She is often seen hanging around with Koyomi Shirayuri. She and Koyomi are Haruna Sairenji's fellow members of the tennis club. It is strongly implied that Koyomi is in love with Sayaka.

Appearance
Sayaka has short brown hair and black eyes in the manga (green hair in the first season anime, and black hair in To Love-Ru: Darkness and a few scenes of Motto To Love-Ru). Her measurements are B75-W55-H80. She has huge breasts in the manga but only 75 centimeters in the anime.

Plot
Sayaka never involved in any major plot but she's featured as one of the most outstanding minor characters in Sainan High. Most of her appearances are for fanservice sake.

Koyomi Shirayuri
Sayaka is often seen hanging with Koyomi. They're both a member of the Sainan High tennis club. One time they were affected by Lala's special Valentine's chocolates, they were clinging on each other as if they're a couple but there's no real evidence that they're actually in love.
