Why?

Meanwhile, in the magical dimension created by Rai, there is Rai who also hasn't come out of the magical dimension yet.

 'What is this? why can't i get out of this dimension? why do i feel like i'm locked and can't get out of here? did anyone take the book from Rusha? tsk, I thought that entrusting everything to Rusha would only be a problem for me.'

 'I don't feel Rusha's presence from outside. What's really going on? this book also seems to be closing, so I can't see what's going on outside of this book.'

 Rai who is still trapped in the magical dimension makes him feel uncomfortable, something is bothering him. It seemed that someone was fiddling with his magical dimension link book.

 Rai can't do much, as has become a rule and limitation in the magical power of the magical dimension that if the owner of the magical dimension enters that dimension, then if the book falls into the hands of someone else then that person suddenly can't do much.
