He is 1 meter 88 tall. Milk brown hair. Moss green eyes. Wearing luxurious glasses. An outstanding genius of the Guillaume family. After the death of his twin sister, he became a foolish fool who liked to dress up as a clown and play mischief. He pretends to be foolish in order to hide his true self and secretly learn about his elder sister's death. Always suspicious and wary of everything around him, even when he is pretending to be stupid and naive.
