Full Metal Panic Fumoffu is the sequel that followed the original series that was released in 2002. Bonta-kun: Best. Mascot. Ever. OK, maybe not best, he can be second place after Nyako Sensei. I watch this much later because my watch order was Full Metal Panic!, Full Metal Panic! The Second Raid (TV and OAV), and this. I did not know this existed till later, so that is the order I went with.
