, the owner of Sofi and co-owner of Erron and Molly.
Erron and Molly's grandfather would always gift the two siblings with lovely Japanese clothing to embrace part of their heritage. Being heirs to a martial artist and having been taught Karate by their father at a young age, Rush's father decided to spoil his beloved grandchildren with lovely gifts, such as clothes and accessories. Though Erron would also love to train with his grandpa, he still gladly accepted the clothes, but is super sensitive because of his sister's teasing. Nevertheless, Sofi compliments her handsome little man as Rush scolds Molly a bit for teasing her brother so.
