Fire Force Omnibus 3 (Vol. 7-9)

Company 8 has been slowly working to expand their team,
but they’re still missing an engineer! They set out to recruit an
exceptionally talented machinist named Vulcan, but they may
have their work cut out for them when the recruitment effort
goes sideways and fighting breaks out. In an unexpected twist,
Shinra comes face to face with his long-lost brother, but the
family reunion isn’t a happy one—Shō has a hidden agenda
to fulfil that will test Shinra’s heroic resolve. Meanwhile, the
rest of Company 8 will each face their own trials.
