I remember it being a story on ao3. Harry makes a friend during muggle school who is japanese and the friend starts bringing him bentonite boxes. The friend has to leave tho after a while. The friends family is some kind of bird creature from Japan. Harry gets sorted to slytherin and Daphne helps him do his hair. The father of his friend gives him a feather he wears in his hair. The friend has 2 or 3 more brothers (not sure if its 2 or 3). At the end of the 1st year at hogwarts the family takes him to japan. Ohh and they give harry some sort of box through which they can pass letters to each other.

Please help me find this fic. I have been searching for a very long time.
