[RED-UGUISU (Yakuwa Ken)] Regu Regu Wan-wan (Made in Abyss)

Reg, a cat‑eared boy with mechanical limbs, shouts "REG!" as his fluffy dog companion presses against him and attempts to fuse, pulling his tail and invading his body. The frantic dialogue reveals his shock at a sudden prostate and broken pee‑pee while he wrestles with the dog’s eager attempts to share its feelings. After a tense "30 MINUTES LATER" card marks the passage of time, he resigns to the bizarre intimacy, accepting the dog’s affection as the scene fades.
