I'm not really understanding the mechanics of the flames and the trail in general. Why do the flames burn mc? What makes this trail difficult? Want are the upper limits of what main character do? Why is there a trail for 3 when only 1 actually does all the work? I feel like the mangaka/author could have done a better job explaining this.
why the time flows so damn fast, before you know it the "5 years passed" comes up. They don't even show anything, they show only small pieces of time and then 2 years later. I never thought that I would dislike when the time flows too fast because usually in mangas the time flows slow
