Kūne, alias Cthugha, is a Cthugan extraterrestrial and cousin of Kūko, mirroring his humanoid form with a taller, more statuesque build and accentuated proportions. Posing as a Galactic Defense Force agent assigned to surveil Kūko’s Earth activities, her true agenda revolves around obsessive collection of otaku goods.

Driven by unwavering infatuation toward Kūko, she emulates his persistent pursuit of Nyaruko through similarly tenacious advances. Kūko’s fabricated betrothal to Mahiro Yasaka as a deterrent plunges her into turmoil, fueling contempt for Mahiro’s perceived frailty compared to cosmic entities and inherited animosity toward Nyaruko, rooted in ancient enmity between Nyarlathotepians and Cthughans.

Brash and confrontational, her abrasive candor frequently sparks conflict, yet she forges an unlikely alliance with Luhy Distone—a Cthulhi alien employed by a competing entertainment conglomerate—defying inter-corporate tensions. Kūne’s chaotic interventions inject comedic friction into group dynamics, juxtaposing unreciprocated romantic endeavors with interstellar rivalries.

Her narrative contributions remain confined to core series events, with no documented expansions into supplementary media.
