Birdug

Birdug is a bird themed superhero and the imaginary friend of Kamigawa Ucheniki, who used his manifestation powers to bring him into existence. He is mainly known for his outrageous costume, and his fun loving personality. He appears in Volumes 3 through 9 of Desune Academy School 14, and has a minor villain arc in Volumes 3 and 4, when he becomes jealous of Kamigawa's Harem.

Introduction:

Birdug is introduced to us first through a series of flashbacks in the first episode of Volume 3, to Kamigawa's childhood, showing him playing with his imaginary friend. Then he is properly brought into the series when Kamigawa manifests him in Volume 3 Episode 2. He starts the series off happy to be alive, and proves himself to be a wacky and fun sidekick.

Villain Arc:

He however quickly becomes jealous of the attention Kamigawa is receiving from their female classmates, and turns on him. This doesn't last long however, as he is quickly defeated in battle, and sent to the reflection beach for most of Volume 4, where he learns to become a better person and makes up with Kamigawa. He only has minor appearances in Volumes 5, 6, and 7, which are largely devoted to the dynamic between Kamigawa and Villain-san.

Academy Arc and Death:

Birdug returns to the spotlight in Volumes 8 and 9, when he helps Kamigawa create Desune Academy School 14, the school for superheros, and enlists as a teacher to Villain-son, Dool Noodle and Kawaii Bandana. When Villain-son's treachery is revealed at the end of Volume 8, he quickly joins Kamigawa in an attempt to protect the school, but after the long battle that starts off Volume 9, is tragically killed by Villain-son, who strikes him on the head with the not yet sentient body of UwU-Chan. Every character previously introduced shows up at his funeral, and his death eventually drives Kamigawa to his murderous revenge rage in Volume 10.
