Ryuusuke Yamino

闇野竜介, Megane, Jormungand
Loki039s second son takes the form of a polite bespectacled boy in his late teens and serves as his housekeeper cook and assistant. He enjoys cooking cleaning and other domestic activities and in the anime he also has an amusing addiction to ordering useless items from mailorder catalogs. His real name is Jormungand also known as the Midgard serpent since his true form is that of a giant serpent that encircles the Earth. Loki rescued Yamino from the bottom of the sea by casting a spell on him thus giving him a human form so that he could accompany his father on Earth for this he is eternally grateful. The revelation of Yamino039s true identity occurs earlier in the manga than the anime and seems to play more of a part in his characterization for the first manga series. He probably wears glasses as a reference to the Indian cobra meganehebi or quotglasses snakequot in Japanese. Source: Wikipedia
