Naofumi’s arrival in another another world doesn’t turn out at all like I’d thought. Instead of being a fish out of water in Glass & Co’s backyard, he ends up in a prison with just Rishia. Both their levels have been reset to 1. Later, Raphtalia jumps out of a pile of hay, revealing that she’s reverted to her previous smaller self. The three may have been tanks in their isekai, but this place seems to follow an entirely different set of rules.
That said, the cell they’re in is unlocked and they still have their weapons (Raph’s sword is way too heavy for her), so they start exploring. They soon find a portal of light that takes them to an isolated island. The sea stretches to the horizon, where it glitches in and out. Instead they head into the jungle, where they slowly start to level up by defeating easy lesser monsters. There’s a refreshing feeling to this, like just starting out on a new JPRG.
When they find a body of fresh water and are attacked by a kappa that’s way too strong for any of them, it looks like they’re about to suffer an ignominious defeat and end up God-knows-where, but they’re saved, by none other than the “Hunting” Hero, Kazayama Kizuna. She’s voiced by Tomita Miyu, who along with Penkin makes this a welcome Abyss reunion.
Before Naofumi, Raph, and Rishia arrived, Kizuna was all alone in this place, which she calls the Infinite Labyrinth. She says she was trapped there by a hostile country, and has long since lost count of how many years it’s been. At one point she even considered suicide, but that was long enough ago that she can talk about it in a cheerful tone. For someone who’s been a alone so long, she’s remarkably well-adjusted and “normal”.
Naofumi proceeds to make an absolute mockery of the untold years she spent here, as the moment she shows them what she believes to be the edge of the Labyrinth, he comes up with a plan to bust them all out. He has her cultivate a Bio Plant Seed, which he then detonates right next to the portal none of them can move through.
The plant starts to grow, and with it the portal grows. I suppose this has the effect of thinning out whatever barrier kept them out of it, because once it reaches a certain size everyone is able to go through it. Naofumi, Raph, and Rishia call out to Kizuna to come with them, and she snags them with her fishing wire, hitching a ride through the infinite.
The four are spat out in a place Kizuna recognizes as the world where she was originally summoned, and as soon as she realizes she’s finally free of the Labyrinth, she leaps on Naofumi and spins around in giddy elation.
While the Labyrinth crisis was solved way too quickly and easily, I still enjoyed this trippy, slightly unnerving, yet fun bridge between the Tortoise arc and whatever’s to come. Similarly, while Kizuna was rapidly introduced and had to spout a lot of exposition (much of it rendered moot by their escape) Tomita made her effortlessly charming and rootable throughout.
