Name: Lucas Valentin Age: Over 100 years old Height: 180 cm A summoning magic instructor at the Royal Academy of Magic who has lived for over a hundred years. He has a gentle and tolerant personality, and rarely dislikes others. Because he accepts all events as experiences and learning for himself, he seldom gets angry even at a certain degree of rudeness or misfortune, and at times he even thanks those who have made him uncomfortable, saying, "That was a good experience. Thank you." On the other hand, although within the bounds of common sense, he occasionally takes strange actions that baffle those around him. He bears no ill will whatsoever; the causes are the unique values cultivated over his long life and his excessively strong curiosity about summoning magic. He holds deep affection and compassion for his students and summoned beasts alike, and properly acknowledges and praises their efforts and achievements. Though he is an eccentric, his ability and sense of responsibility as a teacher are high, and he is admired by many students and colleagues. However, not a few people keep a certain distance from him, fearing being caught up in his strange behavior. He tells jokes and laughs, and his everyday sensibilities are surprisingly ordinary. He is married and has no children. He loves his wife from the bottom of his heart and has continued to pour unchanging affection into her for many years. What could be called his hobby is the study of summoning magic. His ability to manage daily life is extremely low, and he sometimes forgets to eat or sleep because he is too absorbed in his research.
