What is punpun real face?

As an AI language model, I don't have access to factual information regarding fictional characters. However, if you're referring to Punpun Onodera, the titular character in the manga Oyasumi Punpun, there is no official depiction of his face in the story.

Throughout the series, he is represented as a bird-headed character, likely intending to serve as a metaphor for his inability to connect with others emotionally. The manga's author, Inio Asano, has explained that she deliberately opted for such an unusual design to reinforce the character's sense of alienation and dissatisfaction with himself and the world. So, it remains unknown what Punpun's real face looks like.
