The resonating Echo of the sword changes the boy's fear into rage.
Ok so this manga is so BADASS, so the story is basically that the mc was a survivor of a massacre, got PTSD (post traumatic stress disorder), got a sword that i think blocks souls or has souls in them or something, and then he gets revenge (i think) on the people who caused the massacre and some other trash (He killed a fucking (not really) super hero i don't know if he was bad(the hero)), the art is full color and pleasant to the eyes, the characters are fairly good (i like the badass mc's), so basically this is a manga with a bunch sword badassery with EXPLOOOOSIONS, i like this manga, fairly short (24 chapters, i think).
The appeal of this manhwa is seeing Yujin slice things in half. Like, doing that thing where feir sword sends a flying slash through the air which cuts everything cleanly in its path. The artwork carries all the weight, with several of the fights being pretty aesthetically intense and the characters being pleasing to the eye. That said, I don't actually really care for the "slide method" of showing peoples' bodies getting cut in half. It's supposed to show the speed with which fe's cutting, but it just seems like a digital shortcut. Fe fights against people with various weapons and superpowers. The story is that there's a secret organization connected to ability users who sometimes ask people the question "Do you believe in god?" while massacring them. Apparently on a whim, Yujin had been allowed to live after seeing all feir friends massacred and being asked that question, and is now getting revenge. It's, um, how do you say, a weakass premise. It was apparently either cancelled or dropped after Season One, meaning there's no sense of resolution.
