The Kernel (カーネル, Kāneru), also known as "Heaven" (天界, Tenkai) and "Realm of God" (神の領域, Kami no Ryōiki), is the core of the Digital World's universe as well as being God's domain. This place exists in a higher dimension to that of the Digital World itself and all Angel Digimon come from here. It is the primary duty of the Three Great Angels to protect this place and lead God's Army. Rasielmon possesses the mysterious power to foresee everything in the world from there.
Bagramon brought up to Yggdrasill his concern after noticing the human feelings of despair were releasing more dark Digimon and affecting the balance of the Digital World, being eventually banished from the Realm of God.
When Ofanimon (X-Antibody) and Cherubimon (Virtue) (X-Antibody) joined the battle between the Royal Knights and the Seven Great Demon Lords, Seraphimon stayed behind to protect the Kernel. During the final showdown against Ogudomon X-Antibody, Alphamon: Ouryuken, Omegamon X-Antibody, Koufa and Yuuji traveled to the Kernel of the New Digital World, the Realm of God, where they used their own data to stabilize the Old Digital World.
