Personality
Blue Planet is described as a nature lover. He is shown as a warm and gentle person, who loves to look at the night sky. He enjoyed spending most of his time on the sixth floor, creating his own ideal world.

Background
Apparently, Blue Planet began playing YGGDRASIL with a goal in mind which is to re-create the gorgeous natural scenery that had been lost in the World of 2138 due to environmental pollution. At some point in time while playing the game, Blue Planet joined a guild by the name of Ainz Ooal Gown and conquered the Great Tomb of Nazarick. Moreover, later on spending most of his time crafting and redesigning the 6th floor within their guild base was for that sole reason he came to YGGDRASIL in the first place.

The Undead King Arc
Blue Planet's name was mentioned by Momonga after he went outside of the tomb. He wished that Blue Planet could see the beautiful night sky of the New World as he designed the fake sky on the 6th floor.
