Keito is mostly reserved, but becomes outspoken when something he’s passionate about comes up. Keito is relatively tall with short dark green hair and yellow green eyes. He wears silver framed glasses and loves glasses. As a vampire, he has pale skin and sharp fangs. He tends to give lectures that drone on.
