I have 2 questions!

1. Which volume is it that Issei gets sick and the gremory team takes care of him in the human world? I really want to re-read that part which made me laugh when i first read it but i forgot which volume that was from.

2. Which volume states that the birth rate of the devils are low compared to the others such as humans and angels?

Arigatou!
