1179: Theory on Imus Health and Leaving Pangaea

Two things are clear

1. The elders dont want Imu to leave Pangaea, they are all aware of some consequence

2. As soon as Imu leaves, he becomes sick, even coughing up blood

My conclusion from this is that Imu loses his immortality whenever he leaves an area.

This backs up that Imu could've been the person to recieve immortality from the Ope Ope no Mi...

HOWEVER

It only maintains effect, in the origonal room it was cast in.
