"OSway" stands for "Old-school way" - this build is meant to clear the Underworld (in either hard or normal mode) in the absence of a Speed Clear team that can split into multiple tasks at once. It is fairly simple to run and should make for a guaranteed success if used properly. It was designed as a derivation of Kabeway (HM Heroway) using a full-player team for Non-SC runs by the FATE Alliance.
