Out of so many isekai/fantasy out there, I think this one gets Tolkien the most. And unlike its contemporaries, this manga plays with Tolkien tropes and adds its own flair.
For instance, Menel means 'skies/firmaments' in Sindarin. An apt name, considering his epithet (Swift Wings).
The choice of Half-Elves to be mortal or immortal is a callback to the Half-Elven twins in The Legendarium, in which one chose immortality (Elrond) and while another become mortal progenitor of kings (Elros).
The guardians of the forest are also mainstays in Tolkien myths: Old Man Willow, Treebeard, and Melian of Doriath.
I'm curious how this manga will flesh out the Dwarves.
