This is a controversial but vital point of "rawness." The original 2004 release of Heaven's Feel included explicit sex scenes (infamously referred to as "mana transfer" via dragon dreams). The later Realta Nua (PS2/PS Vita) censored these scenes, replacing them with violent, abstract nightmares (blood drinking, neck biting).

The Heaven’s Feel movie trilogy (ufotable) is a visual masterpiece. But it’s filtered raw:

In Fate and Unlimited Blade Works, Shirou’s ideals are challenged intellectually. In Heaven’s Feel, they are shattered physically and emotionally.
