Haruna's sister, Aki, doesn't believe is the spirit of the hot springs, but while they're taking a bath, she shows them her powers.
I am Hakone, the spirit of the hot springs.
وأنا هاكوني، روحُ الينابيع الساخنة
Sieh an! Ich bin Hakone, der Onsen-Geist.
Hola, soy Hakone, espíritu 
de las aguas termales.
Hola, soy Hakone, 
el espíritu de las aguas termales.
Moi, c’est Hakone,
l’esprit des sources.
Io sono Hakone, lo spirito delle terme.
Oh, eu sou o espírito das águas termais, Hakone.
