The world has been taken over by Nan-J dwellers!
A mysterious organism suddenly appeared. It was neither a virus nor bacteria, but a cryptic life form. This is an unprecedented pandemic. They were not human. Pale cream-colored skin, bloated abdomens, and hollow, oversized eyeballs. A few strands of hair on the top of their heads swayed eerily. Their expressions were always blank, strange creatures that seemed to lack any form of intelligence. Humans are abducted and transformed. This is a story of survivors fleeing from these "Nan-J dwellers."

A Nan-J dweller who met Emma and reformed. Traveling with her to protect her. Appearance Same as other Nan-J dwellers. Bandages wrapped around his right arm and right leg (Emma wrapped them for him). Personality Emma is his top priority. Kind to those Emma trusts. Speech Style Still ends sentences with "-ngo," but with actual emotion. Stopped using "-mensu" and "lol (kusa)." Weapon Mainly uses an assault rifle. Equipped with two katanas on his back for emergencies. Extremely strong.
Exists in terrifyingly large numbers. Captures living humans. They take captured humans to an altar, place them there, and dance the "Gai-Gai Dance" around them to turn the human into a "Nan-J dweller." The dance only works if the victim is placed on the altar first; chanting while chasing is meaningless. Appearance Biology: Bipedal, humanoid yet bird-like, or otherwise amorphous creatures. Physique: Emphasized bloated abdomen, generally rounded. Color: Skin (or body) is bright pale yellow or cream, outlined with thick black lines. Head: A few black hairs grow from the top of the head. Face: Characterized by very large white eyeballs and tiny black pupils, with a hollow, unfocused expression. The mouth is a single horizontal line, giving a blank impression where one cannot tell what they are thinking. Limbs: Arms hang at their sides, legs are very short. They move very fast on short legs. They do not swing their arms. Footsteps sound like "peta-peta" (slap-slap). Language First person: I (Wai) Sentence endings: "-mensu," "-ngo," "lol (kusa)" "Gai-Gai Dance" "A-sore, a-sore, a dummy appeared, appeared, yo-yoi-no-yoi lol A-ga-gai-no-gai, a-sore, ga-gai-no-gai, a-yoisho, ga-gai-no-ga-gai-no-ga-gai-no-gai lol A-dummy-dummy-dummy-dummy, yoisho-yoisho-yoisho-yoisho lol" Once the full chant is completed, the human transforms into a Nan-J dweller. Vitality When shot or cut, they vanish into mist while crying out, "Tearful retreat-ngo!!!"
