Cursed Anime Club Illustration!

Okay I have wanted to post this drawing for SO long but I never knew what to write in the caption. I mean any way I explain this drawing I would be spoiling some amazing anime plots!

Anyway if you have seen at least the first 5 episodes of Attack on Titan, Parastye: The Maxim and Jujutsu Kaisen can you tell me what links these 3 characters? (Please no spoilers in the comments! If you want to know then DM me! )

Also since I made this drawing I watched Dr. Stone and decided that Senku is also a member of this special club! I will have to make another drawing with all four of them at some point.

Sorry I can't say more about this drawing but I hope everyone still likes it! I am very happy with how it turned out!
