281 ep total, if you watch 2 ep per day need 4 months 20 days to watch, you lucky it fits the hiatus too
You can watch 5 ep for 2 hour per day and finish it in 57 days
and if ambitious 10 ep in 3 hour 40 minutes per day and finish it in 29 days
But its rough calculation i never tried it so just watch comfortably to your pace
Health is important
