MitsuKoko

MitsuKoko is the het ship between Mitsuru and Kokoro from the DARLING in the FRANXX fandom.

Canon
Mitsuru and Kokoro were in different FRANXX pairings at the start of DARLING in the FRANXX. They barely interacted with each other as they had little need to and shared no common interests.

After Mitsuru got traumatised by piloting with Zero Two, Kokoro started showing concern for Mitsuru's wellbeing, which Mitsuru brushed off as acts of pity. When Squad 13 was rewarded with a short getaway at the beach, Mitsuru found the remains of an abandoned city and wanted to do some exploration. Kokoro voiced her fears of the place, to which Mitsuru coldly told her she didn't need to come if she was afraid and added that he couldn't guarantee anyone's safety. However, Mitsuru managed to save Kokoro from getting crushed by a falling bookcase in an old clinic later, implying he had been following her closely. He also noticed Kokoro had picked up a book about childbirth and reproduction - banned information but chose not to mention it. Following the getaway, Mitsuru later finds out Kokoro kept the book despite it undoubtedly being against regulation.

Fanon
It is a highly popular ship in the fandom, having reached first place in weekly anime popularity charts. It rivals FutoKoko.

Children
Series' finale shows Mitsuru and Kokoro have three children plus one on the way. Only one of them has their revealed name for now:

Ai
Ai is the firstborn daughter of Mitsuru and Kokoro. She is also the first naturally born child to the Parasites after APE's departure.

Ai is the Japanese word for "love" (愛). Mitsuru and Kokoro named her after this in honor of Hiro and Zero Two's relationship.
