Hah! Were Johto of a harsher taste, I would feel quite at home. Sadly, yet fortunately, this realm is free from that strife, so cowering behind your Servant class is needless here.

[ Not a Saber class Servant? Or do his words hide something else... Certainly no Beserker, so that rules one class out. Rider? There seemed to be no transport he could have summoned, and if he was, why not summon that instead of swords? There goes another one. His first reaction to her presence was summoning swords... well, he certainly didn't seem as agile as a Lancer. And, well, he's making no attempt to not be seen and she could clearly sense him a mile away, so... nope on Assassin.

So that'd leave... Saber (if he was still trying to evade on that), Archer, or Caster. ]
