Chacha joins HXEROS as a new member and starts living with the team in the same dormitory. Chacha enters Retto’s consciousness to find the source of his H-energy. While still merged with Retto’s consciousness, she visits the rooms of Maihime, Momoka, and Sora and stimulates their H-energy. She ends up taking a bath with Kirara, which makes Retto antsy. Chacha’s powers are too much for Kirara, who faints from the heat. Chacha realizes that Retto is in love with Kirara and takes control over his body while whispering to him that now is his chance.
I've never seen beings before
that can become sexually excited
Noch nie habe ich Lebewesen gesehen,
die ihren Geschlechtstrieb zur Fortpflanzung
Nunca antes había visto a seres
que pudieran excitarse sexualmente…
Je n’avais jamais vu
d’êtres qui s’excitent
Nunca vi seres que ficassem
sexualmente excitados
