Ewan Amano

Yuu Amano (天野ユウ) is Nene Amano's younger brother, and revealed to be a major villain in the season 6.

Description
When Taiki confrontes Nene in the Forest Zone and demands to know why she is working with the evil DarkKnightmon, she reveals that she is looking for Yuu, and will do anything to save him, even "following the devil himself." For his own part, DarkKnightmon had promised her that he would recover Yuu for her and send the two of them home if she helped him revive the Darkness Loader. Later, when Sparrowmon finds Xros Heart in the Dust Zone, he explains that Yuu is being held hostage by DarkKnightmon himself.

When Taiki returned to the Digital World, Yuu is seen with DarKnightmon as partners, while he wishes to battle Taiki.
