Looks like Berserker has thought up a most cruel vengeance. And then he was a matchmaker.

...for once I would like to read a fanfic. About THIS.

Uhhh, I'm pretty sure he thinks Kariya is Saber because they both have an ahoge. Which is going to really suck for Kariya in just a moment. They do say Berzerkers always end up killing their Masters!

Sad that Kariya has to die because of his ahoge =____=
