Irodori Comics: Scoring Gyaru

On the campus of Naoto Kageyama's school, a special honors program has a unique reward system: the student with the top score on the term exam gets to choose a "servant" from a group of gyaru who will cater to their every need. However, Naoto has consistently fallen short of this goal, never managing to take the top spot. His fortunes may be about to change, but his luck is complicated by the presence of a gyaru who consistently bullies him.
