Made in Abyss Episode 09

Synopsis
Riko and Reg descend through the 3rd layer, the Great Fault, which features a long, vertical shaft. The trip is made more dangerous by the Madokajack constantly seeking prey. Fortunately, there are plenty of Neritantan who make nests in holes along the shaft. Riko uses them as distractions to draw the predators away. Riko and Reg run into the very same Crimson Splitjaw that Reg saved Riko from previously. Reg recalls Ozen's warning: using the Incinerator causes Reg to pass out within ten minutes, and for two hours afterward, it is impossible to wake him up. This would leave Riko completely unprotected.

The two decide to retreat by using a close cave system. In doing so they accidentally stumble into a nest of a Madokajack and with no other choice, due to being in an enclosed space, Reg uses his Incinerator to kill the creature. After he passes out Riko drags him along with her, in order to create more distance between them and the Crimson Splitjaw. During Riko's journey, through the cave system, she gets swallowed by an Amakagame but is able to cut her way out of it by using a small dagger.

Riko manages to get to a more open spot, from which she and Reg will be able to descend to the 4th layer. Moments later, the Crimson Splitjaw shows up again, due to having tracked their scent. Riko gets ready to fight it with the Blaze Reap, but luckily Reg wakes up and, after seeing the situation, leaps forward and hits the Crimson Splitjaw with the Blaze Reap. The Crimson Splitjaw falls off the edge into the shaft, where it is attacked by several Madokajack.

Riko and Reg descend to the 4th layer, which consists of a series of platforms filled with hot water. As they travel, Reg becomes aware of something watching them, that also moves when they talk. He thinks it may be a Delver, but not a White Whistle Delver, though he is concerned that he hasn't been able to locate it yet. Suddenly, an Orb Piercer appears behind them.

Trivia

 * The Anime adaptation of this episode is quite different from the Manga (extended Anime adaptation) because the animators wanted to show the independencies between Riko and Reg, since they had been in survival training, and how they work together in difficult situations.
