Kikaijikake no Saishuu Yuusha
機械仕掛けの最終勇者
A young goddess resembling an android selects Teruhisa Kusaba and reincarnates him into a fantasy world as a hero. He possesses an unusual cheat ability that allows him to overpower enemies and advance through battles he barely understands. As he struggles with the intensity of these conflicts, he discovers that this power is the very force he sought to use against the Overlord. The world he inhabits has cycled through more than 60,000 loops, and his strength may finally break the pattern.
