The story is a rewrite of the Kaixa Gear arc of the Kamen Rider 555 TV series.
Chapter 2 can be seen as equivalent to Episode 5, where Mari visited Smart Brain and encountered the Squid Orphnoch. However, the ending was changed as Masato transformed and saved Mari, revealing his identity and the story then directly jumps into the Kaixa Gear Arc.
The manga was first announced in September 13th, 2019, which is a meme holiday many Kamen Rider fans on the internet partake to celebrate Masato Kusaka's character called "Kaixa Day", based on the Kaixa Phone's transformation key code (9-1-3).
