Nara

You may be looking for the Mystverse stone called nara, or for the fangirl from OFUMREDURE.

Nara is an Agent that occasionally visits Tirsaer and Ryni, usually for no other reason than to annoy them. An apparently indestructible shapeshifter, Nara has a few strange quirks of habit, including usually wearing the shape of whoever happens to be closest at the time. Combined with an unfortunate tendency to wander off at inopportune times without notice, it's understandable why Nara has a difficult time keeping partners, despite the rather useful ability to lure in Mary Sues by taking the shape of their Lust Objects.

As of yet, Nara has no recorded missions, but is occasionally mentioned in the mission reports of RC #5719.
