Yeah, I have to admit that that part is highly amusing. The rest shows a few interesting details, although it needs a translation, really. Rider's summoning involving Sakura invoking a large snake is an interesting touch, and actually showing how the summoning ceremony occurred is also interesting (I'm wondering why Sakura is naked, but I suspect that is just standard practice for when she's down in that basement...), and I'm interested to see what's going on with Rider and Sakura at the end.
