um have you tried reading Tokyo Revengers if not I would recommend it.
read the light novels! They're amazing and they delve a little deeper into their relationships with each other. The anime touches on some of the light novel content (like Dazais entrance exam and Chuuya and Dazai when they were 15). They're available to purchase in english on amazon :)
also Dead Apple just got translated and published, so if you want to read where it was originally created then thats also a plus!
thank you!!! I'll definitely look into it! <3
hellooo i really like this manga and the anime adaption as well, are there any other manga/light novels that i should read concerning bungou stray dogs? would appreciate some help w this ♂
