Reincarnation isn't original by any means, but being an inanimate object is a first for me. Unfortunately the sword has no goals beyond getting generically stronger and finding a wielder. While this is to be expected from a sword, stories based on the premise of fighting and getting stronger rely on such goals so that the MC as well as the reader can determine if MC is still a ways off from the end or if MC begins to close in on what they seek.
The author attempted to balance slice of life with action/adventure and in my opinion failed horribly. Personally I'm a fan of both SoL and action/adventure novels, but some authors get over ambitious and try to do both at the same time and end up not making it flow together very well. This story doesn't weave SoL into predominantly action oriented segments, nor does the story try to weave adventure into SoL segments. It gets to the point where I feel like I'm reading two separate novels with the same characters, one where the characters go on adventures and risk their lives, and one where they wander around having a good time with friends. Also, there is far too much emphasis on cooking and food, I get that Japanese novels like to say that Japanese food is the best food that has ever existed on any world, but there's no reason to let that ideology bog down the story.
The main character group, consisting of a reincarnated sword, a former slave cat girl, and a monster wolf all have traits consistent with personality without a real glimpse of personality itself. The sword is a reincarnated Japanese man who dies and one day wakes up as a magic sword. Throughout the story he exhibits traits of being a gamer type nerd, but he doesn't actually seem to understand how typical RPG games actually function (blame the author on this I guess). He is also perhaps one of the biggest Gary Stues I've come across in novels. Obtaining skills from monster cores he's absorbed, leveling up himself as a sword through "eating monster's' magic stones" which allows him to increase his damage, makes him more durable, increases his ability to be amplified with magic, gives him skill points he can use to level up any of his skills he wants, equipping an increasing number of the skills he has, all while being able to share every single one of his equipped skills with his wielder. I should also mention the inconsistency of the author in making the sword as intelligent or perceptive or oblivious as the situation demands for plot reasons.
The female lead is a typical taciturn loli girl named Fran who's primary traits are that she enjoys eating, beating up on people that look down on her, wanting to get stronger to prove a point, and her obsession with her sword whom she affectionately calls "Master". There are many points in the novel where her brusque way of speaking and overall attitude towards most people are silly and fun to read, but the author goes out of his way to talk about how intelligent "Master" is or how intuitive Fran can be, yet he chooses to solve basically every problem with brute force, because that's literally always the best solution to every problem they face. The wolf is basically just a non-speaking copy of Fran, not much to talk about with that one.
The side characters are what really shine in this novel. Each feels like they could be the MC of their own story. They have various backgrounds, have different ambitions or goals and things that are important to them. They are actually allowed to have both strengths and weaknesses shown throughout the novel without having to immediately rid themselves of whatever weaknesses were shown. It also seems like rather than being given plot armor, the side characters that seemed to have it earned it. Overall, I like many of the side characters more than the main characters
