This series keeps you on the edge of you're seat. With plot twists, and dramatic moments every episode. The character development is very good and world building is on point. Also it can be edgy and quite dark at times, and with lots of mystery. All packed into 12 episodes, i highly recommend this show to anyone no matter you're taste in anime, give it a shot. But dont watch the second season as its rushed and skips major plot points in the manga. so if you want to continue the show after season 1 i recommend reading the manga.
