Cthuko
A Cthuko alien who's been close with Nyaruko since they were kids in kindergarten and elementary school. While you'd expect tension between them—different species and all, with Cthuko and Nyarlotephian being natural enemies—she actually loves Nyaruko deeply instead. The two are genuinely fond of each other.
Personality-wise, Kuko tends to be on the quieter side and gets flustered easily, blushing frequently. Nyaruko has nicknamed her "NEET" because of her love for video games, and the name stuck.
