Shorts center on red panda who releases stress by singing death metal at karaoke

Sanrio began streaming a video introducing a new anime short titled Aggressive Retsuko on Friday. The video introduces the character, and reveals that the short will premiere on April 2 within the Ō-sama no Brunch TBS Saturday morning program.

The show centers on Retsuko, a 25-year old red panda who works in her dream company's accounting department. But it turns out that she is forced to keep doing more and more impossible tasks by her superiors and co-workers. She doesn't talk back to them, but she still has to let off steam, so she ends up going to karaoke by herself and singing death metal.
