When Nagi went into the onsen, she had a drunk-like behavior which was probably due to the affect of the onsen. Hayate went to save her but despite the fact she was naked, Hayate had a very calm demeanor which upset Nagi. She met an alien and from a far distant, something came towards them. Nagi was helping the alien find Maya, the spaceship when something happened…On other matters, Hinagiku and Nishizawa-san were developing a deeper relationship at the onsen. We’ll fully understand the real reason why Nagi went to Shimoda which will conclude this Izu-Shimoda episode!
If you keep that up, she won't stop at aliens next time.
Si sigues con eso, la próxima vez 
habrá más que extraterrestres.
Se continuar com isso, na próxima vez ela 
vai mandar algo mais que alienígenas.
