Bill Randa and Dr. Keiko Miura are where that story really begins. In the 1950s, Bill is a cryptozoologist trying to prove that giant creatures are real, while Keiko studies Titans, or MUTOs, as part of the natural world. Together they help shape Monarch’s original mission, which ties the family to every investigation, cover-up, and discovery that comes later. Their son Hiroshi grows into a major Monarch figure, one far more focused on control. After Hiroshi’s presumed death, the show opens up his double life: one family in the United States, another in Japan. That split pulls Cate, a San Francisco schoolteacher, and Kentaro, a Tokyo artist who don’t know each other at first, into a reluctant search through Hiroshi’s past and Monarch’s secrets.

If you follow the Monsterverse regularly, there’s plenty here to grab onto. Bill sees Titans as a mystery to solve. Keiko sees them as part of nature. Hiroshi sees danger. Cate sees trauma, and Kentaro gets the chaos of it all up close. That’s what gives the series its emotional spine: legacy, secrecy, grief, inherited trauma, and a US-Japan divide running through the center of the story. You can stream Monarch: Legacy of Monsters on Apple TV+, where season 2 premiered on February 27, 2026, according to Apple TV+.
