Episode Summary: Gagumber and Memempu are a father-daughter pair who are constantly at odds with one-another. Despite being a kid, Memempu is extremely precocious and a genius inventor; it’s her goal to become a Marker – an adventurer who explores the underground labyrinth connecting the various remaining human colonies that exist beneath the planet’s surface. Gagumber, despite being a bit of a goofball, still has his fatherly responsibilities to think about, and he doesn’t want his only child to run off and be needlessly killed by one of the terrifying kaiju roaming outside their city’s protective dome. The result of this is that the two consistently find themselves butting heads.
But Memempu has been seeing a mysterious place in her dreams, a white tower above the surface surrounded by beautiful fields. During a visit from Lynda and her father, both current Markers, Memempu receives a mysterious package that suggests her dream might be real. As she begs her father to let her go on a journey to find this place, the city is attacked by kaiju breaking in from outside. Despite the terror of the situation, Memempu still longs to explore. Gagumber decides that there’s only one thing for a father (and retired Marker) to do – go along on his daughter’s journey in order to protect her.
