I'll quickly recreate my review for the novel, however keep in mind that the manga differs quite early:
Pretty straightforward comedic reincarnation fantasy, of the sub-genre Unusual Reincarnation, this time as a Sword of OP +10.
The weakest part is the beginning, filled with the usual dreary supergrinding and superfast leveling. Even if the MC is a floating sword, it gets tiresome how easily he mows down mobs and bosses just like that. The OP-ness of the story comes from the sword's capability to just absorb enemy skills, and then share it with someone wielding the sword. Thankfully, we soon come across our REAL main character, Fran, the kemonomimi child who then becomes the focal point of the story as she cutely OPs everything in sight with her sword and climbs the ranks of the Adventurer's Guild.
OPness levels: mid-high, ridiculously fast rise, but not yet able to destroy everyone; main strength comes from skill diversity and having access to a ridiculous sampling of skills
RPGosity: mid-high, the usual Scan/Appraisal skill things, status screens up the wazoo, Skills being a discrete Thing that you can absorb, stats and damage; all of this is integrated and alluded to by everyone in the story
Cutidity: so cute
Story?: yes, some
Characters?: characters!
The manga, edited and worked on by professionals, takes the weak beginning of the story and improves it 560% by cutting the sword's solo grinding and starting right off the bat with the meeting between the sword and Fran (possibly putting the sword's grind into a flashback, hopefully short). The action scene is more exciting and expanded upon to give everyone more character, including the slavers. Everything is just better.
And this is just chapter 1!
