Destroys a Shed by opening one of Shirou's circuits

Having located what looks like the highest quality one of the bunch-the more he has to work with, the more he'll learn after all-you proceed to try and direct your Od into flowing through that one Circuit...only for it to get wicked away instantly as well. "Oh this is just getting annoying." You mutter. Finally fed up with this nonsense, you open up your Magic Core at full blast, flood the area around Shirou with Od, and then use just a tiny bit of that flood to open up that one Circuit.

Well, the good news was that it worked.

The bad news was that the shed exploded.

Both you and Shirou emerge from a cloud of smoke coughing and holding each other, and you frown at the strange cuts on your hand. You didn't think the explosion was that strong...
