College student Christine Minato is very popular on social media with over a million followers. She uploads photos and videos that make everyone around her jealous. But a man from the Jomon era that Ratman has brought to the city begins to threaten her position. Chris asks Kitaro for help, but he declines because it isn't a youkai. Panicked, She tries all kinds of things to battle the Jomon man. Her actions go too far, causing a societal issue. Those around her start distancing themselves. Having lost her friends, her money, even her standing in social media, Chris' hatred towards the Jomon man grows...!?
A new, no, primitive man like this
will disappear in no time.
رجل جديد، لا بل بدائي مثله
.سيختفي بسرعة
Ein Neuling? Nein, Steinzeit-Kerl wie er
wird im Nu wieder verschwinden.
Este novato… No, este cavernícola 
desaparecerá enseguida.
Este novato… No, este cavernícola
desaparecerá enseguida.
Un type aussi primitif,
limite primate, disparaîtra vite.
È un principiante da due soldi, anzi, un campagnolo 
primitivo, sparirà appena arrivato in città!
Um novato... Não, um homem primitivo
desses vai desaparecer em pouco tempo.
Новый человек... то есть примитивный, 
мигом пропадёт с радаров.
