In a change of pace both neat and foreboding, Girls’ Last Tour ditches its usual cute OP in favor of giving us a couple more minutes of “Life.” Chito and Yuuri enter another vast, city-sized facility, and while they assume they’re the only ones Alive for miles around, the facility is still “alive” with a lowecase “a” due to the lights, fans, pumps, and other various machines still working, even after the civilization that built them fell.
They also find a fellow “living thing” in a single, solitary fish, the last fish in a facility that probably churned them out in the billions in its prime. That single fish is kept alive by the one maintenance robot still functioning, much like the robot in Castle in the Sky, many of its not-so-lucky robot colleagues were not so lucky. Last tank, last fish, last maintenance robot voiced by Kamiya Hiroshi (I think?), and two of the last girls…it’s like a last convention, complete with pool facilities.
Free spirit Yuuri is all too comfortable skinny dipping, but Chito keeps her skivvies on in the presence of the robot, even though his “empathy” is just sophisticated software. But being in the presence of such complex electronic and mechanical systems that still function have Chito and Yuuri constantly wondering what “life” really is. That’s driven home by an effective fast-paced montage of all of the various patterns of sound that emulate the functions of organic life forms.
The fact that evolution bred from rebirth and change is required for life is also explored, with the only other robot at the facility being responsible for constructing or deconstructing parts of the facility as its programming dictates. When that includes the aquarium where the last fish lives, Yuuri spearheads an effort to stop the giant ‘bot.
While there was an early running joke of Yuuri constantly saying they should just eat the damn fish, she gradually develops empathy for it, to the point she’s pulling some Mission Impossible-type shit to strap explosives to the giant robot, bringing it down.
In doing so, Yuuri may have saved the fish and its attendant for now, but without the giant robot the facility will no longer change or evolve. The last robot will cease functioning, the last fish will die, and one by one the last functioning systems in the facility will shut down, in time. And since everything is the last of its kind, that will be all she wrote; no more “life.”
It’s a stirringly bittersweet close, as Yuuri and Chito themselves serve as “mutations” in a system that looked poised to self-destruct anyway (when the giant robot destroyed the fish’s home) before continuing their tour. They mostly agree that “life” means something that has an end…which this episode does with a classic credit roll with a haunting new piece of music.
