There’s other funny moments with the pair as well, like Reigen coming up with a new excuse every damn time he wants Mob to take out a spirit in his place, and the gullible Mob enthusiastically does it.
But on their adventures, the pair do have bonding moments. Mob grows in power and realizes his true potential. Reigen deep down grows to care about Kageyama time and time again and goes out of his way to make sure he’s ok despite his selfish intentions.
Season one nicely sets up the school & suburban setting and slowly introduces the vast amount of colorful characters that make an appearance throughout the show, friends and foes alike.
The opening song (OP) is so catchy and unique to the anime, composed by the ‘Mob Quire’, with bright colors and plenty of images splashed in every frame. The music “[1 mob 2 mob 3 mob 4]” plays off of Mob’s emotional buildup that happens from time to time that makes his inner psyche explode with power.
