Retsuko - Head Desk Slam

Character: Aggressive Retsuko
Franchise: Sanrio

Information: Aggressive Retsuko is a red panda who is a cubicle worker. Outside, she's calm and cute but becomes a metal head when raged. 
She's always internally screaming because the everyday obstacles in life such as irritating co-workers, getting out of bed, and trying to rip off that label on a newly bought product can make her go bonkers.

If you want to know me on a personal level, I believe this is the animal you'll find that I strongly relate to.
You should definitely watch the series, each of them are 5 minutes long and quite enjoyable.
