The Student Council is a powerful club at North High. It includes the club administration committee, which can allow the creation of new clubs and promote them to research society status. Its discipline and clean-up squad ensure that students are dressed properly.
The Student Council President is an operative of the 'Agency', whereas his secretary, Emiri Kimidori, is actually a humanoid interface, using her memory-altering abilities to make it appear as if she has always been a second-year student at North High.
The 'Agency' stole an election for the president, putting him into the role of a "villain" (due to his appearance). His job includes abusing his position to create obstacles to the SOS Brigade, entertaining Haruhi Suzumiya when she overcomes these obstacles.
