Mango is a Nekovalkyrja, Type 33 sprite created by the YSS Sakura as a cook. She tends to threaten anyone who enters her kitchen besides Hanako (and formerly, Kimura Bonichi). Recently (during Mission 4), Mango was added to the crew of the YSS Eucharis as the night cook. She handles midnight meal and breakfast. Despite her usually-friendly nature, Mango is a bloodthirsty killer eager to increase her body count in battle with the Star Army's enemies.
