Trivia
• In the WN, Velzard became the owner of this skill but it was indicated that Shion was supposed to get it. It was indicated by Veldora when he began to wander why the envy in Shion's heart suddenly disappeared. Unbeknownst to them, because of Velda's influence the envy of Velzard's heart became the ultimate skill Leviathan. Thus, Shion became unable to enquire it.
