This is a very generic and inoffensive manga. There's nothing impressive about this, but there's nothing atrocious either.
The story is a very standard Isekai. The setup is so generic that some kind of A.I. could have written it. The MC is a Final Fantasy superfan that lands a job in at Square Enix, but he finds himself far-removed from the games themselves. He's then hit by a truck and sent to a Final Fantasy world with his little sister. There they meet a group of adventurers and learn about the rules of this world. From then on, it's mostly a series of setpieces with
a flimsy overarching mcguffin the characters are searching for. The M.C. does grow throughout the story, which is better thank most other throwaway wish-fulfillment Isekai manga.
The art is actually fairly well done. Kind of busy and overwhelming, but it's nice to look at and very detailed. The character designs are great. They are very reminiscent of other FF properties while maintaining a unique fantasy aesthetic. This holds true for most characters except for a few.
The villains are just stick-figured women with two melons attached to their chests. They are LAUGHABLY bad. Like, holy hell they are goofy.
I know I ragged on this a lot, but it's a fun read for Final Fantasy fans with a lot of fanservice and FF references (especially FFXIV.) It's not something to prioritize or think too hard about, but it's a good read when you want to read manga with your brain off.
