PLOT
[HELIOS] After the 13th class entrance ceremony, the newly appointed rookie "Heroes," Junior and Faith, are assigned to the West Sector. However, the team they're assigned to is unusual, with only one mentor, as per the wishes of Mentor Leader Brad. Furthermore, Mentor Keith has no desire to teach, and leaves the two rookies to their own devices. Frustrated by the lackluster team atmosphere, Junior asks to be transferred, while Faith remains apathetic. Far from improving teamwork, the rift only widens. Meanwhile, an incident caused by [Eclipse] sets the gears in motion that connect the past and the present. It all began four years ago, at [Lost Zero]. --The death of a certain "Hero."
