Oshi no Ko Vol. 4 — Manga Raw / Buy Official

When a castmate is nearly swallowed by a chain of online abuse, Aqua saves them with a reckless gambit that puts himself in the line of fire. The incident showcases his cunning and nerve in the industry and brings him closer to the network that leads to the truth of his mother's death. His growing bond with Kana Arima and his connection to MEM-cho become key pieces on the board. Ruby, meanwhile, starts searching for like-minded partners, and the dream of forming a new idol group begins to move. The twins each pursue the stage their mother once lit—avenger and heir, two paths crossing as the story races into its next chapter.
