And the protagonist of “Kay reacts to the Hakuoki anime 10″ is... Keisuke Sannan!
I think this scene (that I don’t remember going like this in the game) is veeeery important to understand Sannan’s character (and his route even though it was added after the anime adaptation aired). We see in his expression that he’s genuinely worried for Chizuru (maybe even feels guilty), didn’t want to lose control to his Fury self, and that he’s scared and truly sorry for it. Also, he manages to regain control by himself, something to be expected from the Shinsengumi’s colonel!
Even though his methods are not really the best, I think that he chose the only solution he saw viable to stop feeling useless and continue fighting for the Shogun with his comrades, and always tried to do what he considered best for everyone.
I’m sad that we mostly get to see the Fury side of him and because of that we really sleep on the fact that he was the Shinsegumi’s colonel for a reason and that he’s been with everyone since the Shiei Hall days.
TL;DR: Thank you Hakuoki anime for giving us this scene/animating it and not leaving it as a 2-seconds thing so we get to see a bit more of Sannan’s struggle!
