Got to love the whole theres an extremely low chance of Ichigo not being allowed to come back but dont worry heres soul society tickets to go and see him whenever you want lol.
i find that curious because if Ichigo is dangerous to the point of not being allowed to go to human world ever again then ...
If they go to SS, their body would adapt better to the abundance of reiatsu.
Maybe if Ichigo come back, everyone who can feel reaitsu would be overwhelmed...
Didn't reall think about it, but maybe it's something like this.
