Leo is an ordinary 17 year-old young man who has a rather short height for his age. Despite this, he possesses an extraordinary ability called the "All-Seeing Eyes of God", which are covered by his eyelids that are usually closed. He tends to express his emotions openly, whether they be excitement at something new and enjoyable, fear of the insanity and dangers of Hellsalem's lot or annoyance. Despite having the powers of the All-seeing God's eyes, he refuses to abuse it.
