Two stories are told in this episode of 3G, which have thesis statements of their own, but tie into the central idea that Rei and the Kawamoto sisters aren’t in a one-sided deal. He’s not the only one getting something out of this. And he’s well aware he’s getting something out of this.
The first begins with the not-surprising realization that Rei has shoji buddies with far more forceful personalities, which he’s nonetheless able to coexist with on his own terms. Nishioka has made Rei his personal rival, and Matsumoto wants to beat him so he can appear on TV for his ill grandpa who taught him.
Matsumoto and his longtime friend Smith are also nice guys, so when they go out to celebrate at the hostess club where Akari works, they’re nothing but respectful (and appropriately in awe) of the stunning Akari, and don’t make their 17-year-old Kohei drink liquor. Akari confides to Rei that these are the kind of guys to hang out with.
It hearkens to the first time Akari and Rei met: when some not-so-nice guys did make Rei drink himself into a stupor (which probably didn’t take much, considering his size and complete lack of tolerance). It was Rei at his most vulnerable, and he had no way to hide it.
That didn’t matter at all to Akari, who took him into her home and took care of him. It’s a pretty good chance he got alcohol poisoning that night, so when he couldn’t force himself to vomit some of it up to ease his pain, she showed him how. Concerned, gentle, caring: both the Akari at home and Akari the Hostess are equally amazing and beautiful to Rei.
Before he met Akari, Rina, and Momo, Rei saw the new town he lived in in monochrome, as if walking through a dream. But from the moment Akari welcomed him in their lives and told him he could come by anytime (and meaning it), color returned to his life, and with it, a measure of joy.
The second half, “the other side of the bridge”, marks the difference between the cold industrial/commercial side where he lives (akin to Ayanami Rei’s memorable digs) and the warm, homey, comfortable side where all the Kawamoto sisters are, as well as the food.
Rei can never refuse Akari, and he doesn’t when she invites him to join them for Obon. Because he knows, the Kawamotos have suffered profound loss just as he did. He helps fill the void in their lives so it doesn’t fill with grief, and they restore color to his. It’s a nice arrangement, and watching it play out is enough to melt the hardest heart.
