Hiro

Over the time spent together he began to reproduce feelings of romance with Zero Two, and when their relationship as partners began to take a turn and slowly crumble, he reawakened his previous feelings during childhood with her, along with his current feelings of love. The two eventually began a relationship together before their demise. Although motivated to fulfil his duty as a parasite, he later makes it his purpose in life to free all the parasites from APE’s control and he selflessly sacrifices his own life to protect his friends and the planet.
