Being the younger brother, Birch is always getting into mischief. Whether this be playing tricks on others, or being clumsy enough he falls and breaks his antlers - Birch is always up to something. He is constantly seeking to prove himself to his older brother, who he admires greatly. They have a competitive relationship, to which Birch seeks out validation and attention - sometimes not in the best of ways. But their brotherly love is a bond like no other.

The foliage on his antlers change with the seasons, and fall away completely in winter. Perhaps because of this mutation, he has influence over plant growth - or is it just a trick of the eye?

Birch's luck influences others, helping them to achieve the best versions of themselves.
