Dekao Oyama (Dex) Dekao is Netto's best friend, and favourite sparring partner when it comes to Navi net battles. Dekao's Net Navi is called Gutsman, who seems to fit Dekao's fisique perfectly. Dekao is a fairly good net battler, more often using his strength head on rather than strategy. Dekao has a huge crush on his friend Meiru, and often gets jealous when she pays Netto more mind than him. ^_^;

Dekao's hair is rather strange, poor kid is so young and almost already bald. ^_^;
