Help with anime gift 🎄

Hi guys, my 14 year old daughter is really into anime. I know absolutely nothing about the genre! I do know that her favorite character is Suguru Geto from Jujutsu Kaisen. I would like to get her some Christmas gifts related to what she loves. I have found a funko pop of him, and a t shirt so far. She loves watching so many different shows on CrunchyRoll. She reads a lot of Japanese horror books (manga?) as well. Any ideas that are a little more inspired than just a Barnes and Noble gift card?
