Useless Knight? My Mounts Conquered Every Era

A once-celebrated academy prodigy is branded the most useless class after awakening as a Knight, and his girlfriend abandons him at once for a corporate heir while onlookers jeer. Hidden beneath that label is his true calling as Chronicle Knight, heir to the Throne of Mounts, able to summon legendary steeds drawn from every age of history. As he calls forth mounts and machines from different eras, he turns the people who mocked him into enemies who beg for mercy. A threat from beyond time now looms over the kingdom, and he must hold the line alone.
