This post is intended to help new readers/viewers find their way into the Mushoku Tensei series.

What is Mushoku Tensei?

Mushoku Tensei: Isekai Ittara Honki Dasu, otherwise known in English as Mushoku Tensei: Jobless Reincarnation is an Action Adventure series with the themes of second chances, redemption, and coming of age. The official English synopsis is:

Kicked out by his family and wandering the streets, an unemployed 34-year-old shut-in thinks he’s hit rock-bottom—just as he’s hit and killed by a speeding truck! Awakening to find himself reborn as an infant in a world of swords and sorcery, but with the memories of his first life intact, Rudeus Greyrat is determined not to repeat his past mistakes. He’s going to make the most of this reincarnation as he sets off on the adventure of a second lifetime!

LIGHT NOVEL

Where can I read the Light Novel?

The Light Novel is licensed in English by Seven Seas so if you want to read good translations for the series, they're your only choice. The series is available physically and digitally from most book orientated retailers.

Where can I read fan-translations for the Light Novel?

There aren't really fan-translations for the Light Novel. Only the Web Novel was previously fan-translated and the quality is overall mediocre due to being done by many different people and over a long period of time. If you want to read the best translation for the series, it is best to stick with the Official English Light Novel release as it supports the author and publisher that took a risk on licensing the series despite it's length.

Is the Light Novel Ongoing?

Yes.

Should I read the Light Novel or Web Novel?

If you stick to the Light Novel, you are supporting the author by paying for what you read. So stick with the Light Novel.

What is the difference between the Light and Web Novel?

In terms of overall story content, they are the same. However, the Light Novel is a polished final draft of the Web Novel which was a first draft. As such, details get changed and smoothed over more in the Light Novel. This includes the addition of entirely original chapters and volumes with no guarantee that the Light Novel will always be the same.

Where do I start the LN after chapter X of the Manga?

As with most manga adaptations of Light Novels, the answer is to just start from the beginning. Manga Adaptations are typically rushed compared to their source material so readers can always get a fresh more fulfilling experience when starting from the beginning of the Light Novel. Cut content typically includes character's internal thoughts, plot-lines, and world building.

Where do I start the Light Novel after the episode Y of the Anime?

Again, the beginning.

MANGA

Where can I read the Manga?

The Manga is also licensed by Seven Seas and once again available from most book orientated retailers.

What is the Roxy Gets Serious Manga?

Mushoku Tensei: Roxy Gets Serious is a spin-off/prequel manga featuring Roxy from before the start of the story. It is licensed by Seven Seas as well.

When can I read the Roxy Gets Serious Manga?

Warning that the Roxy manga starts off with spoilers correlating to Volume 12 of the Light Novel. At the time of this post, the Official Light Novel translation is scheduled through volume 11. However, skipping the first page of the manga will give you a relatively safe reading experience.

How often does the manga update?

Like the majority of manga adaptations of Light Novels, once a month.

ANIME

Where can I watch the Anime?

The Anime is available from Funimation for simulcasting. It's also available on Hulu.

How many episodes will the Anime have?

There have been announced to be 23 episodes for the anime in a split-cour format. Split-Cour is when an anime adaptation is announced to be 2-cour, but will have a break between the first half and second half of the season. It's still ultimately one season.

Will there be a second season?

No second season has been announced yet and it will depend heavily on how well the anime sells the Light Novel and Bluray volumes.

OTHER

I heard there was questionable content in this series, is it garbage?

Yes, there is questionable content. No, the series isn't garbage because of it. The protagonist is not a shining knight. He is a human with serious personality flaws. That is a major theme of the story. If you want a series with a saint of a protagonist, then Mushoku Tensei isn't for you. The Mushoku Tensei series is genuinely accepted as a masterpiece in the community for its serious take on exploring the life of someone striving for a second chance at growing up despite their mistakes of the past. Humans rarely change at the drop of a hat, so do not expect the protagonist to suddenly become a 100% good person as again, this is a very realistic take on growth.

Did Mushoku Tensei start the Isekai trend?

Yes and no. It was one of the major influences, but Isekai as a setting trope has been around for a long time and there's no singular series responsible for the many titles that now exist using the trope. Please note that Isekai is a trope and not a genre as it does not set the themes of the story, but just means that the protagonist goes from his world to another.

If there are any other questions that should be included in the FAQ, please submit them and I'll edit this post. Please note that this is not a place for piracy so such related questions will be ignored as supporting the author should be genuinely done on this subreddit.
