Yes, we did. It was fairly well-known, in fact.

[ Assassin's pretty sure that Caster was banging her Master in part for that reason, so he's seen at least its effects first hand. He doesn't know how common it is though, and that would probably shock even Kojirou. ]

It's difficult to say, although I must admit I feel at least a lot more energetic.

[ Where, though? ]

So I suppose I could fight a little while more.
