Iruma's season 2 keeps everything you love about the first season, and comes into its own. Even if you've read the manga and think you dont need to watch the anime, watch it. A bunch of great tiny bits are added to make the story flow better and add more depth to characters/tease stuff earlier. More characters are introduced and kept, and almost all of them are as interesting and unique as the main trio. If you haven't watched season 1 yet, watch it. This show is fucking great. Also, there's an especially SPICY arc, a fan favourite. It is being done justice. Enjoy.
