Serani Poji

 is an indie Japanese music unit by video game music composer Sasaki Tomoko.

It was founded in 1999 as part of the soundtrack for the SEGA Dreamcast game ROOMMANIA#203. "Serani Poji" was the name of a fictional singer in the game. However, the album released before the game came out, and it became quite popular, so it continued on as an unrelated project afterwards. Releases were fairly regular until 2004 when the band went on extended hiatus. In 2009, Sasaki announced that she would be releasing a self produced album under the band's name on her MySpace, and it was released in 2010. After another long period of inactivity, Sasaki announced that she was working on new music in 2017.

Originally, Fukutomi Yukihiro was the producer, but he left the project in 1999, passing it onto Sasaki, who now is the sole member and producer.
