I'm currently watching Mob Psycho 100, the last episode of season 2 was Mob fighting Keiji Mogami. Which chapters of the manga do the season 1 and 2 of the Mob Psycho 100 anime cover?
Season 1 covers Volume 1 through 6. Season 2 will most likely cover Volume 6 through 16.
Season One ends on Chapter 50 ("No Changes") but also includes an omake chapter ("Romance and Impulse".) at the end of the episode.**
Season Two is most definitely going to cover Chapter 51-101 which is the ending of the series.
