Nyarko is usually happy and hyper, but she's caught a cold and is stuck in bed. Nyarko is smitten by Mahiro, who's being a little nicer than usual. It's then that they get a report that an intruder has shown up at the North Pole. They leave Nyarko behind to recover and find that Mi-go was waiting for them...

Ahora que lo pienso mejor, 
¿era necesario que viniese?
Ahora que lo pienso, ¿de verdad tenía que venir yo?
Pensando bem, teria sido 
melhor se eu não tivesse vindo.
