Namiko is the sister of The Emperor and helps your character from the beginning of the game. In the Story, she offers to help your character if you help her find The Emperor. The reason for this is unknown at the beginning but throughout the Story, Namiko reveals that The Emperor is her brother and she wants to find him. You help Namiko reunite with her brother by defeating him, which in turn gives you the title of The Emperor.
Namiko appears in Boss Battle and Battle Royal Events, rewarding a Small Gas Tank if she is defeated. Her name is often mispronounced as 'Naviko' in the Story by your character and other characters.
