Bungou Stray Dogs 2nd season is the my favorite season in Bungou Stray Dogs series.
In my opinion, the first season mainly focuses on Armed Detective Agency and Port Mafia, the main character and people around him, introduces each side character with their ability/crazy personality in each episode.
When you know the relationships of each character, like basic knowledge (but also enjoyable), then you can understand the sequel seasons.
The first 3 episodes of 2nd season focuses on Osamu Dazai and the dark era of him, introduced the importance/badass new character in Port Mafia gang.
Many secret in the first episode will be clear in this season. So I
suggest to watch 1st season first.
I love the first 3 episodes of this season the most. (They can make you easily love personality of Dazai lol). But if you prefer the main character, our tiger Atsushi, more than Dazai, don’t worry. This season will shows you the
improvement (and action seen) of our tiger.
The art and action seen are not that remarkable but the character development and relationship between them are the best of this show. (and hair/cloth of each characters is very unique, I love their designs.)
I personally love that they keep how opening with letters like in 1st season.
I personally like opening and ending of this season more than other season.
