Chapter 110

How It Began (それが始まり) is the one hundredth and tenth chapter of Oshi no Ko manga series. It is written by Aka Akasaka and Illustrated by Mengo Yokoyari.

Summary
During the filming of That Was the Start, Ai approached Gotanda to film a B-Komachi documentary. He was reluctant at first but ended up agreeing to it. Most of the footage were filmed, with the final segment being the dome performance, but since Ai was murdered, the documentary was never completed.

Aqua and Gotanda tried to get people on board for the 15 Year Lie movie with the script in hand, and Kaburagi was one of those who was sweet-talked into joining the team.

The provisional cast list consists of:
 * Ai, played by Akane.
 * B-Komachi members, played by Ruby, Mem and Kana.
 * President of Strawberry Productions, played by Melt.
 * The manager Miyako, played by Frill.
 * Lalalai's headliner/Biodad, played by Himekawa

Later, Aqua visits Ai's grave and tells her "I'll fulfill your actual wish."
