Ewan Amano

Yuu Amano (天野ユウ) is Nene Amano's younger brother, who was said to be held hostage by DarkKnightmon; however, DarkKnightmon was actually his Digimon partner. He eventually reveals himself as being DarkKnightmon's willing partner, and the possessor of the original Darkness Loader.

Personality
Yuu is quite sadistic, and enjoys tormenting Digimon as if they were his playthings. He will even force DigiXroses on his own allies, with little purpose than to toy with them.

Description
When Taiki confronts 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.

As Taiki returns to the Digital World, Yuu watches from the Pandæmonium with DarkKnightmon, and states his wish to battle Taiki.

In Honey Land, Kiriha spots Yuu in the Forest, and he's later seen after the battle against Zamielmon. Kiriha talks about the mysterious kid with blonde hair to Taiki and Nene, which is when Nene starts suspecting that her brother is nearby.
