Just read the first volume, good story but crappy title. I think the title is longer than Hyse's journey from dead weight to weapon master. I also don't feel like he is really an S rank adventurer, he just has an OP ability with no downsides, unlike say the prince, Cless. Sasha is kinda similar, plus it was way to convenient that she just suddenly evolved and awakened an even stronger ability.
Besides the title, I was looking forward to an actual journey, not thrilled with the use of weapon master as the name of his ability. Weapon master implies the ability to use any weapons, but he is only able to use the "modern day" weapons from his little book. Feels like something else would be more appropriate, like Arsenal Master. I wonder if this is a translation issue or a cultural one, with Japanese weapons like katana being viewed as something special rather than a type of sword. Otherwise, what are all adventurers arming themselves with if not "weapons", where they should know what that word is even if they don't understand the ability itself.
Final gripe, adventuring should primarily be a male profession, even with the abundance of capable female characters. So why is the princess assigned to the male S rank rather than the female S rank?
