don't forget the Red target locks go as well, really fun for fighting against ATC Vader or the V1 Inquisitor
I think that's definitely the RAI, but RAW I'm not so sure:
If an effect removes a blue or red target lock token from a ship, the matching red or blue target lock token is also removed (unless the blue target lock is assigned to another ship).
There's an exception for moving a blue token, but not for red tokens.
So you move the tokens, but as soon as the red ones are removed from Manaroo, those locks are broken.
As soon as any red target lock tokens are moved, Manaroo doesn't have to worry about them. But they're not broken, just transferred to some unlucky schmuck that happened to be flying with Manaroo. Remember target locks are an elastic thing. Once you've got a ship locked, extending the range can't break that lock.
But because there's no range stipulated on who receives the transferred tokens, the smart move would be to assign them to a friendly ship that's out of range of the ship with the blue target lock token.
