After the elves Iris and Aegis, Ursula, the head of the dragon, moved in.
A powerful race, the dragon Ursula, was a problem child who looked down on other races on a case-by-case basis.
Ursula made a disturbing call to his teacher, who was scolding Ursula as a teacher.
He responded to the call and was locked in Ursula in a closed room alone.
