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, when DarkKnightmon opened a portal to the Digital World for Yuu, and claimed to be taking him to a world where nothing really dies or gets hurt, Yuu revealed his true persona. With the excuse that the suffering he causes isn't real, this 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.

Yuu 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.

Eventually, when the Xros Heart United Army arrives to Bright Land, Yuu offers Twilight's assistance to Whispered in eliminating them with Hell's Field. But as Kiriha holds off their enemies, Taiki infiltrates the black castle where Yuu is before finding himself in a sword fight with the boy. After learning how he and DarkKnightmon met, Taiki reveals to Yuu that what DarkKnightmon have told him about this war being a game was a lie. Refusing to accept it, Yuu Digixroses Tuwarmon into DeadlyTuwarmon Hell Mode before Shoutmon x7 defeats him. But as Tuwarmon spirits a horrified Yuu from the site, the boy asks him if what Taiki said is the truth.
