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.
My skin's smooth just from 
being in it for a moment.
أصبحَتْ بشرتي ناعمة بمجرّد بقائي فيه قليلاً
¡Esto me pone la piel muy suave!
¡Esto me deja la piel muy suave!
À son contact,
ma peau est devenue toute lisse.
La mia pelle è diventata
subito morbida e liscia.
Bastou tocá-la e a minha pele ficou lisinha!
