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.

Appearance
Yuu is a blonde, short boy. He wears black suspenders with plaid maroon-purple shorts. His shirt is grey with a red tie, and his shoes are black with white socks. His eyes, as Nene says, are very similar to Taiki's.

Personality
Before Yuu came to the Digital World, he appeared quiet and compassionate. He cared greatly for even the smallest forms of life, like a butterfly, and hated bringing anyone to harm.

However, as soon as DarkKnightmon opened a portal to the Digital World for Yuu, he revealed his true persona. This Yuu is quite sadistic, and enjoys tormenting Digimon as if they were his playthings, while still maintaining a facade of childlike innocence. He will even force DigiXroses on his own allies, with little purpose than to toy with them. He is an excellent strategist, able to come up with good battle actions on the spot, something which even DarkKnightmon praises him for.

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. She runs off to find him, but is shocked to discover the cruel monster he has become. Yuu tortures her using Doumon's illusions, and despite Xros Heart showing up to rescue her, they are only able to drive off Yuu and his allies, rather than defeat him.
