Shinra Kusakabe is generally understood to have a son with Iris and a daughter with Inca in the Fire Force ending.

Quick Scoop

The final manga chapter is the main source people point to, and it strongly suggests those two children, even though the story does not fully spell out every relationship detail.

What fans debate

  • Some readers think Iris is the primary partner because of the son.
  • Others point to Inca because the ending implies a daughter with her.
  • There’s still some fan debate about whether the panels confirm marriage versus just parenthood.
