Kuchel Iegu

She is a well-known eccentric magician in the Principality of Mefi, who is only interested in studying the ecology of monsters. Her suspicious appearance and selfish behavior make her shunned by others, but the purpose of her research is to find a way to communicate with hostile monsters, develop magic for that purpose, and spread the magic she has developed. Her dream is noble, but in reality, she is only interested in learning about the ecology of monster girls and is strongly attached to seeing the reaction of different species to sexual intercourse, which is not normally possible. However, she believes that making unnecessary sacrifices would be detrimental to her future research, so she asks Avaro, who is an "apostle of God" and can maintain an absolute advantage over any monster, for help.
