Well, I asked YandereDev on Twitter about it. Senpai doesn't even have a name! Since his name won't be mentioned anywhere in the game (since he can be male or female.), the character simply gets a title; Senpai. In other words, Senpai is the best and most popular student in school which is why everyone calls him Senpai.
