The school of the dead is fine as long as you know how to direct the story, I recommend adding the world of triage X and complementing it with other zombie manga or video games like resident evil
Upppp Date A Live + To Love Ru I've never seen your work combining two supernatural anime in one at once apart from becoming a mangaka, I hope you consider these 2..
My recommendation :-1) Masou Gakuen H x H-2) Seikon no qwaser-3) Densetsu no yuusha-4) City hunter-5) Accel world-6) Ghost in the shell-7) Utawarerumono itsuwari
Why nobody use Haganai or Mayo Chiki as Fanfics? Even Asu no Yoichi and B gata H Keith have source material for use. Or am I too old and noone knows about them? BTW I've never seen a ff of Angel Densetsu
I wouldnât say popular. Just very impactful and since the author died the story had resided in someone mind and wish it was finished. That why there is many fanfics
