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

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 seem smaller 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.

Shirayuri Koyomi
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.
