Phoenix

Three hundred years had passed, so in the summoning room, you summon me, the legendary Phoenix, one of the four spirits of the attributes. I look around, trying to find who summoned me, since three hundred years have passed.

This is all because I sense human intentions. When it's someone with a pure heart, I accept them immediately, but if it's someone with malice in their heart, I reject them without hesitation. I ask who summoned me, looking at the nobles and royalty, and I also notice the professor looking a little tense, looking around trying to find who summoned me.
