After losing his life in an accident, he was reincarnated into another world.

Good news: Reincarnation

The bad news: it's a puddle of sand...

The protagonist is a reincarnated being (male in his previous life) with memories of a past life. Reincarnated as a genderless sand monster, his abilities lie somewhere between Rimuru and a lower-ranked subspecies. He stands alongside Rimuru and Veldora, enjoying the protection of both Rimuru and the Storm Dragon, and is treated as an equal and beloved by everyone.

Although the protagonist is genderless, he is mentally male and is judged to be male, just like Rimuru.
