In the eyes of most Lenneth appears to be just a normal girl. However that is how she is in public places, when in private and allowed freedom to do as she pleases she is shown to be a very perverted girl for her age. With fondness for getting blushes out of people she can at the most random times say perverted statements and is also rumored to even go as far as touching and groping if it means getting the blush out.
No one really knows why it is she likes to get people blushing or at what point it started. Part is of is stated is because that she is often hyper and seems to have never ending energy especially when she consumes a lot of candy.
When she's not being perverted and hyper she can be a somewhat well mannered and nice girl. It is widely known by friends and family on how clumsy she is which can be bad since Lenneth is part angel and has powers that center around it. She has a lot of strength and weight that doesn't show on vision alone but one trip and even trees will sink trying to support the combination of her surprising weight and power.
To prevent this Lenneth keeps her powers in check by focusing on limiting herself so that it doesn't happen so often. She is a 12 year old girl by nature with the ability to change her age at will. So she can be as young as 2 or as old as 50 if she so chooses. Lenneth does not use this power often so she is normally always seen in her 12 year old form. She can also change her appearance between two looks, pink hair and blue eyes or silver like hair and gold eyes.
Lenneth keeps hidden within her hair as an attachment a gem of which when brought out with only her magic can expand and become a magical spear which is actually the majority of her weight when it is equipped on her. The spear cannot be broken by normal means and it contains power of the Valkyrie making it a very powerful weapon that hits much harder than Lenneth herself could possibly hit. Knowing this Lenneth does not openly use the weapon out of fear of damaging the world itself on one wrong heavy swing.
She has not used her power to it's full extent and does not plan to try.
