Hmm... On paper, there's a lot of stories like these. Fantasy stories featuring an OP young man with his trusted X, wandering the realm and meeting new people. This story certainly doesn't aim to reinvent the wheel. There's also a potential romance that hasn't bloomed but I'm already somewhat icky about. It's between the MC, a 3000-something years old young-looking man, and a young girl he met in his first town. The story takes its time letting the FL grow, but... the MC has known her since they're a child. It's a bit difficult to forget that part. But at the same time, I enjoyed reading thisa lot, more than a lot of their peers.

Part of it is the flow. The story controls its pacing really well, trimming the excess fat and making sure that only the most interesting and meaningful events are portrayed. Sometimes a couple chapters is spent for a single day. Other times months or even years passed in a single chapter. The story slows down and rushes up as much as the narrative demands, and that makes for a story arc that is never boring.

Second is the characters. While none of the characters in this story are particularly unique or inventive, they are pretty fleshed out and nuanced. The protagonist, for example, resembles many stereotypical slacker college-aged manga protagonist in both appearance and mindset and personality. His dynamic with the dog, meanwhile, follows a specific subgenre of "A boy and his X" stories where the X in question is more of a bickering partner than it is a cutesy mascot.

But by borrowing from other genres, this story gets to add some weight to the characters. By sticking to its college-aged mindset, the protagonist becomes decently fleshed out beyond your usual fantasy / isekai protagonist. Meanwhile his interaction with the dog keeps him grounded and makes his OPness less apparent.

And when they inevitably interact with typical fantasy elements (like magic runes), the interaction results in something refreshing.

Side characters are also pretty enjoyable here. They aren't just brain dead set dressing for MC to show his OPness; they are each their own individuals, possessing a separate strengths and weaknesses and growths. Some of them are even capable of challenging and overcoming MC in different ways.

Most importantly, the side characters are friendly and human. They react to MC in different ways. Even the ones who are saved by MC are treating him with gratitude and friendliness, but not blind worship.

All of this combination keeps the story grounded. The story isn't too dark but neither is it shallow. The creator takes all of these well-worn tropes of other genres and used it wholeheartedly here and they all do their jobs pretty damn well.

Again, I deeply enjoyed it.
