"Watashi" no Theme - The Tatami Galaxy OST

The song "Watashi" no Theme, from the anime The Tatami Galaxy (四畳半神話大系 Yojōhan Shinwa Taikei).
I do not own the show, nor the original soundtrack. The Tatami Galaxy belongs to studio MADHOUSE, along with its rightful owners. The soundtrack is composed by Michiru Ooshima.
Anyway, I wanted to upload this because only the piano version is available, and I personally prefer this one.
