My point is i'm not convinced that the rain in that last panel wasn't caused by the MitD but for it to only affect the area around O-Chul, (i.e. not be planet wide), it would have to be targeted on him. Which means that the MitD must somehow have been able to track him down despite the Cloister supposedly blocking all that stuff.

Now obviously the MitD isn't aware he's done this, so he's not consciously tracked him down, (i..e it's another case of achievements in ignorance for our cute little monster san) or whatever but i'm still not clear on weather there's anything besides epic magic than could track him through Cloister.
