Ewan Amano (天野 ユウ Amano Yuu?) is Nene Amano's younger brother, and the reason that she is in the Digital World. Some time ago, Ewan was tempted into the Digital World by AxeKnightmon, who told him that no one could get hurt in the Digital World, and without knowing about his role in Ewan's disappearance, Nene later accepted AxeKnightmon's offer to serve him in exchange for his help rescuing her brother. It is soon revealed that Ewan is actually a true partner to AxeKnightmon, and the true General of the Midnight army.
Ewan is a short blond boy with gray eyes. He wears black suspenders with plaid maroon-purple shorts with a pocket on each side. He also wears a grey shirt with a red tie, white socks, and black shoes. According to Nene, his eyes are very similar to Mikey's.
One year later, Ewan is quite a bit taller, and usually wears a yellow button-up shirt with white pants, and gray and green sneakers with white soles.
Like Mikey, Ewan is an excellent strategist, able to come up with good battle actions on the spot. Before Ewan came to the Digital World, he is quiet, compassionate, and above all emphatic to all life. When he was young as he accidentally kill a butterfly before, an young Samuel Nakaoka the Second appears which used his revival powers to heal the butterfly. After reviving a butterfly, Ewan decides to follows him much as Samuel Nakaoka's annoyance due to his shyness and clever behavior as he ran off only Ewan continues to follows.
