Nisu no Meo-Eryutoron

The youngest sister, she is very apologetic. In the first fight, she uses her ship's shield as a battering ram, not unlike Madoka's usage of shields. However, she is seen to be apologizing throughout the fight. She pilots the Red Snapper Extra. She is comparable to Ayano, however Ayano seems to be more proactive than Erytron. Like the other Red Snappers, her name is an allusion to the color red. Her name is probably a Japanization of erythron, an element of the blood-forming system involved in the production of red blood cells. (Source: Wikipedia)
