also can someone add Tohno, Shiki from Shingetsutan Tsukihime to the list? he can't remember anything that happened before his accident
Edit: Also add Archer from Fate/Stay Night forgot about him x,x he wasnt summoned by a powerful wizard i think so he couldnt remember anything
Edit 2: Ikaros from Sora no Otoshimono idk if this counts but her memories and emotions were locked up until later in the story
Morimiya, Yorito from Sola
Tennouzu, Kagura from Speed Grapher
Kusaka, Yuu from Ayakashi
Kasugano, Midori from Midori no Hibi
Casshern from Casshern Sins
Sogoru, Kyo from Zegapain
Misaki, Shizuno from Zegapain
Komori, Tarou from Ghost Hound
Almost all the character in Higurashi no Naku Koro ni except Furude, Rika because they are all living in an unending cycle...
What about Cloud Strife from FFVII: Last Order OVA?
And Nigihayami "Haku" Kohakunushi from Spirited Away?
I think we could also add Watanuki from xxxHolic (after all he paid a part of his memories in order to have his wish granted, no?)
