Command Rebirth: The Greatest Commander's Second Chance

When the greatest commander died, instead of passing on to the afterlife, he was reincarnated in a fantasy world. Knowing nothing but cold logic, how will he cope in a realm that defies logic itself? This will be a tale about how a man, who lived covering not himself, but others in blood, living a life full of regret, tries his best not to make the same mistakes that led to his downfall. Though, for someone who is more experienced at reading emotion rather than feeling it, it might be difficult.
