Zero Unit

The Zero Unit is a mysterious symbol that is often identified with the mythological "Keter" of the Sephirot. It appears on Calumon, Sakkakumon, and Gallantmon's Aegis. The symbol takes the shape of one giant triangle formed from four smalkler ones. Interestingly, the Zero Unit also bears resemblance the The Legend of Zelda's Triforce, which is said to posess the power of the gods. It also resembles the Mitsu uroko of the Japansese Hoji Clan.
