As a part of the Otome training, Arika's Coral class begins a 100 km hiking trip through Aries. With randomly chosen pairs, the students enter into wilderness, when things start to go wrong for Arika and her partner Erstin. A snake bites Erstin, the nanomachines within her fail, and the bracelets used to call for help break down. A mysterious figure attacks Arika. (Source: Wikipedia)
