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 ends up following the smell of Baracocha fruit emitted by an Amakagame and ends up falling in its feeding opening. Riko is able to cut her way out of it by using a small dagger. [Anime only]

Riko manages to get to a more open spot, suffering the 3rd layer's strains of ascent in the progress, 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. [Anime only]

The resulting chain of explosions from the hit [Blaze Reap isn't used in the manga] cause the Crimson Splitjaw to fall off the edge into the shaft.

Afterwards, Reg and Riko continue onwards and soon can see the scenery of the 4th layer.
