Good Bye, My Secret Friend
Synopsis
Based on Saibara Rieko's manga, Ike-chan to Boku (a.k.a. Good Bye My Secret Friend) tells the heartfelt story of a young boy named Toshio and his imaginary friend Ike-chan. Toshio's floating blob of a friend has two big eyes and a mouth, and changes colors and sizes depending on the mood. When Toshio is sad, she turns small. When Toshio makes friend with a girl, she turns bright red from anger. Ike-chan stays by Toshio's side as he grows older, but the day he finds his first love, Ike-chan disappears from his life. Child actor Fukasawa Arashi (Helen the Baby Fox) takes the leading role in this affecting fable about childhood, friendship, and growing up from director Ohoka Toshihiko. Popular actress Aoi Yu voices Ike-chan.

How many hands made this film
The scale of the collaboration
Principal cast & crew: 15
These are the principals we have on file — the full crew ran to the hundreds. Every film this size was made by far more hands than any credits list ever names.
Why a floor?
This is a minimum, not a total. We only count the credits we’ve captured so far, and coverage is uneven — a blockbuster might show a few hundred names while another of the same size shows a couple dozen. The real crews all ran into the thousands. The number here only grows as full credits are enriched — so we frame it as a floor, never a headcount.
