Arobrine Tree

An ARBORINE TREE is the only thing that survives and keeps things surviving in the Lightless Realm. It is the reason why the kids and Tsugumi survived in the realm. 


The Arborince Tree's seeds also help people survive in the Lightless Realm as long as the person holds it. Though, the fruit can only survive in the Lightless Realm, as they wither away when outside the Lightless Realm itself.
