Kakegurui××

- Both anime deal with protagonists who are young people addicted to gambling. - Both shows are psychological in nature and have a survival game feel to them. - They all gamble with their lives,freedom and bodyparts and you constantly get to see the terror going on inside their heads when stuff isnt going their way. - both shows are full of powerhungry psychopaths and show the worst of humanity. 

These two anime are very similar for following reasons: -Both are extremely over-the-top, and indulge in insanity. -Both have very solid sound, visuals, and outlandish characters -Both have very strong emphasis on certain ideologies (for Hellsing the honor, and for Kakegurui the thrill of the gamble) -Both have an unstoppable main protagonist, who is at the very depths of madness. -Both could care less about plot -While Hellsing is very heavy on violence, Kakegurui has a very sexual nature to it, with a tinge more insanity than Hellsing. The turn off for most people is the plot, but if you are looking for an entertaining thriller, then this is for you.  

Both anime involve gambling of sorts and each episode keeps you in suspense, wondering what will happen next. Both also contain a psychological element associated with taking high risks that keeps you interested. Basically, if you liked this Kakegurui, I highly recommend that you try Dorei-ku The Animation. 

Both anime involve games with very high stakes... Both anime also uncover a character’s true personality while participating in the gamble/games.
