Ginga Patrol Jako

Retired researcher Omori’s quiet life on a remote island is interrupted when Jaco, a Galactic Patrolman, crash-lands there and moves in with him. Omori has been living alone while continuing his research into time travel. Jaco is a first-class space officer, but his habits can make him difficult to live with. The two must get along long enough for Jaco to protect Earth from a dangerous threat.
