Berry Oz is a character from the television anime Shin Bikkuriman. Within the story, he serves as the guardian angel of the Time Castle, a location that holds a vast collection of sacred boxes, each capable of reflecting different moments in time.

His background is tied to the legacy of a previous figure from the larger Bikkuriman series. Berry Oz is established as a descendant of the angel known as Corner King. This lineage becomes a significant part of his identity, especially when he encounters the characters Head Rococo and others. A key moment in his personal journey occurs in an area called the Rubicon Area, where he learns a shocking truth about his own nature: he is not a pure angel. Instead, he belongs to the same era or generation as characters like Marco and Cocky. The revelation of this fact causes him great distress.

Regarding his role and abilities, Berry Oz is primarily defined by his duty as the protector of the Time Castle, indicating a position of significant responsibility. His primary motivation appears to be tied to his identity and his understanding of his own existence. The shock he experiences upon discovering his true lineage suggests a personality that values purity and a clear sense of self, making the realization about his origins a profound and challenging turning point in his development. His key relationships are connected to this past, particularly his link to his ancestor, Corner King, and his interactions with Head Rococo and the others who help uncover the truth about his generation.
