Ep. 19: Lala Builds a Drill to Find Hot Springs While Rito Faces Yami's Test

19

Lala watches a commercial for Tsumata Misami Hot Springs and demands her own, prompting Rito to fetch a drink. On the way, Yami attacks him as a test, but he reveals Lala is building something, causing her to depart. Rito returns to find Lala has constructed a large drill to dig for a spring. Mio, Risa, Ryouko, Yami, Haruna, and Saruyama join the excavation. The group discovers Tokugawa's treasure and Atlantis, which Lala ignores due to the lack of hot springs. They eventually locate the Seven Colored Hot Springs. The girls enjoy the spacious waters, while Saruyama and Rito are confined to a cramped spring. Saruyama attempts to harass the girls, leading to a chase involving Risa and Mio. Rito intervenes, and they encounter Ryouko and Yami, who attack them with hair for being ecchi. Lala tells Haruna to leave to find a spring for Rito's house. Rito and Haruna converse until Lala warns them of an accidental underground volcano strike. They encounter a mole civilization seeking to rule the surface, but the moles are killed by magma. Everyone returns safely to the surface.
