Attack on Titan: No Regrets

A shoujo manga offshoot delves into the past of Levi and Erwin. In their youth, Erwin Smith was already making rapid strides in the Survey Corps, the last bastion of humanity in the fight against Titans, the cannibalistic beasts. Erwin was focused, pragmatic, and unfeeling, with a head full of stratagems and plots. Meanwhile, beneath him lay a hidden world of destitution and poverty known as the Underground, where people are born and die amidst the trash discarded by the Capital. The sly and nimble Levi survived here through his quick thinking and agility. Yet, their paths cross, and the two competitive and driven men are pitted against each other, but who will emerge victorious?
