Luft Lamprogue

Eldest son of the Lamprogue family. The next candidate for the head of the Lamprogue family. He has a personality completely opposite to Gly, and when monsters appeared at his residence, he calmly gave instructions to the maids. He has been concerned about Seika from a young age, but as a brother, he didn't know how to interact properly, and time passed. Even so, after Seika grew up, he taught her the sword skills he learned, and on her birthday, he was the only family member to give her a glass pen as a gift, showing he is a kind and caring older brother. Seika also affectionately calls him "Brother Luft."
