This is just my guess, but I think maybe Info-chan's true identity differs each time you play, that is, a random student (except for rivals) becomes "Info-chan" each time you begin a new game.

This only makes sense if Info-chan is indeed the final boss. She wants to eliminate you in the final week, but you don't even know what student she is! So you must investigate her real name, house, etc. before confronting her, or else you'll inevntably be defeated by her.
