I Decided to Become a Demon King and Become a Student First.

Suddenly one day, Su Mo was bound by a system that claimed to cultivate the devil. It said that it would cultivate Su Mo into the strongest demon king in history! So he took Su Mo through the dimensional wall and came to the second dimension that thousands of otakus dream of. But tell me what you mean by asking me to be a student, and what it has to do with the devil. Also, I can still understand the appearance of Kasumigaoka Shiha, Yukinoshita Yukino, Gogeng Ruri, and Shiina Mashiro. However, what the hell is Fuyuki City? The co-author is still a hodgepodge of Type Moon and daily series. It seems that I, Su Mo, will no longer be bored on my journey to dominate the Nine Heavens as the Demon King...
