Fate/stay night [Unlimited Blade Works]

Shirou and the others fight off Kuzuki and Caster. However, Shirou loses all feeling in the left half of his body as a result of forcibly using too much mana. Rin visits him at home the following day under the pretext that he missed their regular check-in, but she then stays the night for some reason. And then, when Archer sees Shirou’s condition, he says that he has seen such symptoms before. (Source: Official Site)
