Mitsuru

Mitsuru (ミツル) is one of the main characters in DARLING in the FRANXX series. He's a Parasite with codename "326" of Thirteenth Plantation, where he's partnered in boy-girl pair with Ikuno to pilot a FRANXX called Chlorophytum.

Appearance
Mitsuru is a very clean and proper student with sharp features. He has slicked back brown hair and piercing deep green eyes.

Personality
Mitsuru is full of pride and a strong cynical personality. He finds Hiro a rival.

History
One of the orphans of the Garden, he was raised along with the others and watched as Hiro slowly lost his ability to pilot. During the events of Episode 3, he and his partner had trouble getting Chlorophytum to move and so he volunteered to ride with Zero Two in an effort to contribute while showing up Hiro. This act ends up costing him as he was unable to handle the strain and suffered injuries as a result.

Hiro
In the past, Mitsuru seemed to have admired Hiro and his ability, citing that they thought he would be the one to lead them and thought strongly of Hiro as a rival. However, as the years went by and his abilities decrease, Hiro's image in his eyes deteriorated to the point where he found himself unable to stand the sight of it.

In Episode 03, when Delphinium, Argentea and Genista are in need of assistance fighting klaxosaurs, he asks Zero Two to pilot Strelizia with him, because he believes he can pilot it because Hiro did. After successfully connecting Strelizia and piloting it, Mitsuru boasted about how he could pilot it without fainting, unlike Hiro, and tried to take over as her official partner until he gets injured and passes out by the end of their mission.

Ikuno
Mitsuru doesn't seem to have the same affinity with her as his partner that the others do with their counterparts. He blames her for their connection failing in Episode 3, telling her not to even bother when they couldn't get Cholorophytum to function and then attempting to trade up to Strelizia with Zero Two without regards for her feeling.

Etymology
Mitsuru's nickname may use some of the numeral's readings from his real name "Code:326": mi from 3, tsu from 2 (ツー) and ru from 6.
