A Record of Ash & Ruin: The Grieving Lands - Chapter 38Book 2: : Straight Shooter

Finding himself in an Last Airbender without an airbender around, a transmigrator waterbender goes on an adventure to stop the worst from happening to him.

Amamiya Hiroto is unlucky. His life consisted of misfortune after misfortune, culminating in an unlucky death during an incident on a school boat trip, trying to save a girl he barely knew. After death, he met a god of reincarnation who requested that the hundred or so dead passengers—one of them being the girl he tried in vain to save—be reincarnated into another world.

Growing up in a place where the rule of the jungle is law, the simple yet cunning Shaar is thrown into the chaotic world of war and political turbulence. After a chance meeting with a mysterious young girl, his destiny is forever changed as he embarks on a journey, joining the Byzantine army and climbing its ranks. With his bizarre beauty standards, will he ever return the affection of the girls that will follow him? Will he ever learn about his real parents? What lies ahead of him is a journey of strange humor and adventure.

I cut from south to north,

I cut from white to black,

I will cut down the thousand mountains and the ten thousand waters,

I want the world to know who I am!

I am Gu Zhan,

Gu Zhan who wants the whole world to surrender!
