What Are Light Novels and Why Do They Matter for Anime?

Anime vs Light Novel: Should You Watch or Read?

Once you fall in love with these anime, you might wonder if you should also read the light novels. Here are some simple points.

When anime is enough

• If you only want the main story and key emotional moments
• If you prefer visuals, voice acting, and music
• If the anime covers most of the important arcs, like Toradora! or Spice and Wolf (season 1 and 2)

When the light novel is worth it

• If the anime ends before the story is complete, like Re:Zero or Overlord
• If you want more inner thoughts and side stories, like in Oregairu
• If you want to see planned events that did not fit in the anime

Both versions are valid. It depends on how deep you want to go into a series. Starting with anime is usually easier. If it becomes a favourite, the light novel can give you the “full version” of that world.
