Fate/stay night: Unlimited Blade Works 2nd Season, Re:Zero kara Hajimeru Isekai Seikatsu Recommendations
Fate Stay Night is originally a visual novel with three routes in which the hero will make different choices in favor of one of the heroines. (Saber / Rin / Sakura)
Like Re Zero, there will be several scenarios.
Both animes have a fantasy world where the use of magic predominates.
Although Re Zero appears initially as a series rather comic, later the series turns out to be more serious and psychological as much as Fate Stay Night.
