Poporon is an angel who appears as a supporting character in the anime Dropkick on My Devil! She was originally a subordinate of the higher-ranking angel Pekora in Heaven. When Pekora fell to Earth, Poporon was promoted to take over her position. Later, the demon Jashin-chan ate Poporon's halo, which left her unable to return to Heaven and confined her to the human world. Because of this, she believes she must kill Pekora so that Pekora cannot come back to Heaven and reclaim the post, and she also wants to kill Jashin-chan for the loss of her halo.

While living on Earth, Poporon goes by the pseudonym Amatsuka Noel. She supports herself through multiple part-time jobs, working as a waitress at the Genesis Ramen restaurant and pursuing a career as an idol singer. Among the people in her circle, Jashin-chan is the only one who continues to call her by her human alias even after learning of her true angelic identity.

In appearance, Poporon is a teenage girl with long blonde hair and green eyes. Her sweet, angelic looks contrast with a more calculating side. She has a sharp tongue, tends to make selfish decisions, and is willing to scheme against others when it serves her goals. At the same time, she has shown genuine acts of kindness, such as helping injured friends and supporting charity events. She is also unsettled by Yurine, whose harsh treatment of Jashin-chan frightens her, and she dislikes Pino, a feeling that goes back to their time together in Heaven.

As an angel, Poporon has supernatural abilities. Using her angelic powers, she can manifest war weapons such as a rocket launcher, and like Pekora, she is able to survive a lethal hit from a demon. Throughout the story she remains a recurring supporting figure, and her character is shaped by the tension between her self-serving ambitions and her occasional good-hearted actions.
