Mmmh...Just something on my mind...Might it be the end of the Gantz missions ?
You see, during the battle against the oni-boss, that the timer suddently stopped, and also, that people were able to see the gantzers. Well, that bothers me. Cuz it destroys all the rules of the game Gantz was playing.
My point is, now that there's no limit, in time, and in telling people about Gantz, the story might be headed to an all-out war against the aliens, and Gantzers won't be called in the black ball room anymore but will just fight anytime anywhere against the aliens...
Well, tell me if my idea is just stupid.
