1Rm’s Gigant Rider

reincarnated as a nameless commoner on raniakea, the continent of magic and steel, with memories of 21st century earth. to escape the life of a commoner, who is almost like a slave, he must lift the 'magic stone' and become a giant rider. ‘straighten your back!’ ‘tighten your belly!’ ‘take a deep breath into the bottom of your abdomen!’. he uses knowledge from his previous life as a trainer to accumulate magical power as if he were exercising, and climbs the ladder of the social hierarchy.
