Actually the "Second line of defense" also checks whether you've modified any other student to look like Osana and trigger "her" - but that specific check has a bug and doesn't work (at least as of the Jan 4th build) - So yes, it works for now, but don't expect it to work in the future. Currently the only way of adding the real Osana, along with her daily routine (and the task that you can perform for her) is to modify game code. Not too difficult if you know what you're doing, though I think it's immoral to distribute that information after Yanderedev's explicitly said it's against his wishes.
