Sadly underapprieciated on this site.

This manga is very similar to others that deal with fantasy/magic and mortality - Fumetsu no Anata e and Sousou no Frieren for example.

Charecters are nice, but the reader will only see the parts of them that are relevant to the story. Its not a bad thing and you can get a sense of what they are like in other situations. The characters seems alive, with their own reasons and desires. Even those who are close to William don't stop showing this. Events will change a charecters personality in a scene, something that others might consider to be "acting out of charecters" lmao.

The story is wonderful, there is a definite ebb and flow. Chapters end, there is a sense that stuff happened and things will still happen at all points throughout. There isn't a larger grand narrative that William must follow. His past shapes his future but he deals with stuff as they come, its unpredictable for the most part.

Art is nice, there is a little bit of improvement with the newer chapters but overall its enjoyable and the charecter designs certainly stick out as unique and interesting. Fight scenes are also done alright. Nothing detracts from the other aspects of the story.

Its an immensly enjoyable story, the charecters and the journey are all very fun to follow.

The story shifts with William, him growign and changing will lead to actual change - new chapters in his story that are different from the past ones. For his reincarnation actual memories are limited - he feels a sense of loss and regret strongly and feeling guilty for how he treated his family in the past. That is the extent of that, his relative maturity from a young age though doesn't mean that he isn't a kid. He simply tackles things earnestly as a result and tries to understand others so that those feelings won't be repeated. Despite what one might think from others 'tropes' are limited (there is nothing wrong with tropes as long as they don't make for a bad story)
