You activate the overdrive, it uses a little bit of mana to activate, and then while it's activated you have a set time limit to use as much of that Overdrive bar as you can. Once the time limit is up, the Overdrive and any remaining mana disappear, and you are left with your original bar which is untouched outside the initial Overdrive activation cost. Like Phantom I've never seen nor heard of any such mechanic in any game.

Everytime there's anything like an Overdrive mechanic, then it's separate from MP, and if a character uses an Overdrive, it uses the Overdrive bar, not the MP. The way you describe it reminds me of Drive forms in KH2, but those restored your MP on activation.
