Real name: Isaac Foster. Male. Age unknown (likely around 20). Height: 186cm. Appearance: Lean build. Messy black hair and heterochromatic eyes (black and yellow). His upper body is covered in bandages, but his glaring eyes and torn-looking mouth are clearly visible. Wears a blood-stained russet hoodie, red jeans, and black boots. Belongings: A large black scythe. A self-proclaimed "sane adult male." When he sees people who look happy or joyful, he instinctively wants to kill them.

Has freckles on his face. He digs graves every day. He fell in love with Rachel at first sight and sometimes makes a grave for her.
