Celestiel

What Celestiel says

This was where the stadium of the empirical era stood. Even today... Don't you think it'd be a good place to hold a battle? Like a Summoner's duel, for instance... Ah, excuse me for my late introduction. I am Celestiel the Summoner. And that is my comrade Phantasm, the unicorn. Please try not to stir him up since he is quite an ill-tempered boy.
