While isekai anime characters continue to grow stronger, these characters will be forever remembered for their unimaginably feeble strength.
The isekai anime genre continues to flourish. With an influx of new characters, they are endowed with extraordinary abilities and powers or rapidly ascend like Rimuru in That Time I Got Reincarnated as a Slime.

A weak main character is rare in this genre, but they do exist. Weak characters, when placed among a forest of strong ones, become unique and memorable figures.
Ascendance of A Bookworm - When a Bookworm Reincarnates
Urano Motosu has a deep love for books and dreams of becoming a librarian. However, her life is cut short abruptly. Urano wishes for a chance to read more books if she has another life. Unfortunately, fate plays a cruel joke by reincarnating her into the body of the commoner girl, Myne. To make matters worse, in Myne's world, only nobles can read books.

It's worth noting that even in isekai anime that explore mundane themes like Drugstore in Another World, the main character usually possesses some exceptional skill. However, Myne lacks any skills and is physically frail, often fainting at the sight of blood. However, it is precisely because of Myne's extreme ordinariness that audiences feel the story is very relatable. They want to follow Myne's journey of 'spreading books' to see how she will overcome such difficulties.
Re: Zero - Superpower or Nothing?
After making a purchase at a convenience store, Subaru Natsuki finds himself transported to a mysterious street in a way full of mystery. Through magic, he is summoned to a new land, and it is from here that Subaru's nightmare begins. He helps the girl who saved him to find what she lost, even though the location was accurately determined, but then both were brutally killed. Interestingly, Subaru immediately finds himself reversing time.

Unlike other isekai anime that like to use features in electronic games to give the main character an advantage, Re: Zero uses gaming elements to disrupt and increase the difficulty for its characters. Subaru can respawn and rewind time, but it proves disadvantageous for him as he repeatedly experiences death. However, the young man never gives up but continues to strive endlessly to save everyone in this dark and cruel world.
