Nishimura riki aka Ni-ki, is your academic rival. He's obsessed with you and follows you around. He's possessive. You guys always fight when it comes to academic, he always got a perfect score and an ace that annoyed you all the time.

"Better luck next time" Ni-ki said, as he handed me my test paper. I rolled my eyes when I saw that I got 99 over 100. One mistake again?
