In their late year of elementary school, Chiyuri started dating Takumu causing Haruyuki to become more distant. At night, he will often get dinner at Chiyuri's place with her mother Momoe cooking for them before going back to his empty house. Haruyuki spends most of his times after his parent's divorce playing with Takumu and Chiyuri.

After his parent's divorce, his custody was given to Saya. As a child, he was friends with Takumu Mayuzumi and Chiyuri Kurashima. This is implied to be the reason why his duel avatar is a metal colour. In the light novel it was stated that it was about neither of them wanting Haruyuki. It had been hinted that Haruyuki overheard his parent's conversation before their divorce. They then divorced when Haruyuki was seven. Haruyuki is the child of Saya Arita who met and married Haruyuki's father while studying for a Master's degree in Tokyo. However, as Silver Crow, he is more confident and rather crafty to the point that it was comparable to Yellow Radio. Haruyuki is also rather indecisive and often doubts himself. He is also very determined to keep his friendship with Taku and Chiyu after the many problems between them and because of that determination, he strives for the best. Later on in the course of the plot, he begins to admit that beyond helping her with her goal of reaching level 10 and knowing the purpose of Brain Burst, little by little he discovers that his dream is in fact, to always be by her side for Kuroyukihime is the person he loves the most even though he does not have the courage to tell her, despite knowing that she also loves him unconditionally. However, after meeting Kuroyukihime and receiving Brain Burst, he can stand up for himself and help Kuroyukihime in achieving her dreams.

Haru is rather timid at first due to Araya bullying him.
