Is Chokotto Sister coming back?

Chokotto Sister ended on December 20, 2006, on Chiba TV.

It was a Japanese anime series that aired in 2006, centered around the story of Haruma Kawagoe, an only child who longed for a sibling after his mother miscarried a baby. The series explored themes of family, hope, and the magic of Christmas as Haruma received an unexpected gift — a little sister named Choko — on Christmas Eve, fulfilling a childhood prayer he had nearly forgotten.

The show was a drama and anime hybrid that depicted Haruma's emotional journey and the special bond formed with his new sister. It was based on a heartfelt premise where a young boy's wish was granted in an unusual and touching way, set against the backdrop of the holiday season.
