Sonny Boy’s finale begins boldly, with what amounts to a stirring five-minute music video. We follow Nagara, who has slipped right back into his usual existence. Things are so normal, he sometimes wonders if he was ever really adrift in the first place.
Notably absent from Nagara’s high school is Mizuho, whom Nagara looks up and waits outside her school’s gates, only for her to not have any idea who he is. You and I know how much Nagara grew while adrift with Mizuho, Nozomi, and Asakaze, and yet this world seems almost cruelly intent on keeping him isolated and alone.
His present existence back in his original world lies in stark contrast to the surreal, beautiful, and fantastical journey he and Mizuho undertake to get back to a world they’re certain hasn’t changed, even if they have. They tie themselves together, run out of the space elevator, and keep running, even when God tries to stop them. Asakaze bids them farewell, unable to follow even though there’s nothing left for him there.
The flashback to Nagara and Mizuho’s escape serves as a bridge between Nagara’s post-return life and Mizuho’s. Mizuho notes that “everything is gone” from the two-years-plus they were drifting. While Nagara has a part-time job, Mizuho spends her evenings sneaking into their old school and breaking a glass. But a cat doesn’t come delivering a new one; it just stays broken. That’s as it should be…so why is it so sad?
At least we learn that Mizuho was simply messing with Nagara when she pretended not to know him; maybe it was just that seeing him again got her old defenses up. And yet these two people who suddenly find themselves strangers in a simultaneously recognizable and unrecognizable world can’t help but spend time together, basking in both that contradiction and in the knowledge that the two of them are different from everyone else in terms of where they’ve been and what they’ve seen.
There’s a elegiac quality to their interaction, like they were the last surviving members of their unit in some long-finished war. Yet Nagara can’t help but worry that one day he’ll forget what he and Mizuho are feeling right now, and go adrift all over again. Before they part, possibly for good, Mizuho tells him as long as a part of him is still on that island, he’ll be fine. They’ll both be fine.
The episode ends with a third music video, focusing on Nozomi, but wordlessly, until we cut to Nagara preparing to inspect a bird’s nest at the station, only to find Nozomi has already rescued a surviving chick. Nozomi recognizes Nagara from middle school, but unlike him and Mizuho seems to have no other memories of their time in those other dimensions.
Ultimately, Nagara seems fine with that, and fine with the fact Nozomi quickly runs to another guy who I believe is Asakaze. It would seem that by dying in that world, Nozomi’s existence transferred to this one…or something. No matter; I too am glad she’s still alive, bringing light and energy to dark and sullen places.
What I’m not glad about is that this spells the end of Sonny Boy…or at least it should. This just felt like such a wonderfully self-contained and authoritative twelve episodes, my urge for a sequel is tempered. Like Nagara back in his home dimension, everything that should happen will happen.
