Himekawa needs more power to fight against the tri-headed dragon that caused her so much trauma in her past.  But the pleasure of the Climax Hybrid goes against the strict and disciplined life that she's forced on herself after she failed to protect the people boarding the Tokyo megafloat.  It's up to Kizuna to break down the walls she's built up for herself, and teach her to enjoy the ecstasy she needs to defeat the enemy.
I can't believe anybody but me could 
do a Climax Hybrid with Kizuna.
Dass noch jemand außer mir
mit Kizuna Peak Hybrid durchführen kann …
Kizuna no pudo hacer un Climax
Hybrid con alguien más.
Kizuna no pudo hacer un Climax
Hybrid con otra persona.
Je suis la seule à avoir réussi 
une transfosexion ultime avec Kizuna !
Impossibile, sono l'unica a poter raggiungere 
il culmine dell'Hybrid con Kizuna!
Eu não acredito que a Hayuru 
faria Climax Hybrid com alguém.
