Bom Cornwall (ボム・コーンウォール) is the owner of the Gnome's General Store.
Bom is a Gnome with white hair and brown eyes. He wears old gray-blue clothing and a red pointed hat.
Bom used to buy Lili's stolen goods even though he knew that she changed her appearance using Cinder Ella and didn't report her. He later showed his kindness again when he agreed to hide Lili from the Soma Familia.
- Bom's appearance resembles that of a garden gnome.
