Have you tried watching the future diary? Also danganronpa is not a yandere anime but I high suggest with katekyo hitman reborn. They are really good in my opinion
Good Morning short-story-fanatic Thank you for adding Last Refuge of Humanity to your reading list :) I really appreciate it and hope you enjoy reading Elisha's tale.
Omg, I just have to do a call out to @newfiebear's story "The Loner Girl"! It is such a good story, great plot line and just amazing! If you ever get the chance I would highly suggest reading it!
